1
Which of the following best describes the function of the first sentence of the passage about women and music?
Rationale
<h2>It establishes a point of view regarding a phenomenon.</h2>
The first sentence of the passage about women and music sets a specific perspective or stance on the topic being discussed, framing the reader's understanding of the historical context and societal attitudes towards women's roles in music during that period.
<b>A) It provides a basis for understanding the nature of musical compositions in Europe from 1300 to 1566.</b>
This choice suggests that the first sentence serves as a foundational overview of the musical compositions of the era. However, while the passage may discuss compositions, the initial sentence does not primarily aim to inform about their nature; rather, it focuses on a specific viewpoint regarding women's participation in music.
<b>B) It presents a reason to explain the lack of musical compositions attributed to women from 1300 to 1566.</b>
While the passage may address the absence of compositions by women, the first sentence does not explicitly provide a reason for this lack. Instead, it emphasizes a particular perspective, rather than delving into causation, making this choice inaccurate.
<b>C) It introduces a hypothesis that accounts for inconsistencies in the historical record.</b>
This choice implies that the first sentence proposes a hypothesis regarding historical inconsistencies. However, the sentence's primary role is to express a viewpoint rather than to hypothesize or explain discrepancies in history, which makes this option misleading.
<b>Conclusion</b>
The first sentence of the passage about women and music effectively establishes a viewpoint on the historical role of women in music, guiding the reader's interpretation of subsequent information. It does not serve as a basis for understanding compositions, explain their absence, or introduce a hypothesis. By presenting a specific perspective, it frames the discussion and influences how the rest of the passage is perceived.

It is fair to say that the discovery of chimpanzees using tools in the wild (van Lawick-Goodall 1968) was one of the most significant discoveries in field primatology and perhaps in animal behavior as a whole. This finding not only questioned the long-held assumption that using and manufacturing tools were the hallmark of humanity, but also reinvigorated the study of cognitive processes in apes. I say reinvigorated because tool use had been used by psychologists to investigate ape cognition long before its discovery in the wild.
Both Köhler's and Yerkes' pioneering work in the 1920s on ape problem solving drew heavily on tool use. Yerkes saw tool use as an example of ideation, thinking in the absence of the actual stimuli. whereas Köhler saw it as an example of finding indirect solutions when the direct route was not possible. Köhler emphasized the insightful nature of several tool-use episodes, and he contrasted such a sudden mode of solution with the gradual trial-and-error learning that Thorndike had described with hus puzzle boxes Historically, this is the forerunner of a debate between association (ie, apes respond to the presence of certain observable cues but without any real causal understanding) and reasoning that continues unresolved today

Which of the following can be inferred from the passage about the study of cognitive processes in apes?
Rationale
<h2>It had produced little in the way of dramatic results in the period between the 1920s and van Lawick-Goodall's discovery.</h2>
The passage suggests that while tool use in apes was studied prior to 1968, it lacked significant breakthroughs until van Lawick-Goodall's observation, highlighting a gap in impactful findings in the field during that period.
<b>A) It had produced little in the way of dramatic results in the period between the 1920s and van Lawick-Goodall's discovery.</b>
This choice reflects the passage's indication that the study of cognitive processes in apes had been relatively stagnant, with no major advancements noted until the significant discovery made by van Lawick-Goodall, which revitalized the field.
<b>B) It has been sharply divided between those who study apes in the wild and those who study apes under experimental conditions.</b>
The passage does not mention a division in the study approaches; instead, it discusses historical perspectives on tool use without contrasting field studies with laboratory experiments. Therefore, this inference is not supported.
<b>C) Until very recently, it had not fully assimilated van Lawick-Goodall's discovery.</b>
The text does not imply a delay in the assimilation of van Lawick-Goodall's discovery; rather, it emphasizes the importance of the discovery itself for reinvigorating the study, which suggests a swift recognition of its significance.
<b>D) Until van Lawick-Goodall's discovery, it was dominated by those skeptical that apes possessed cognitive understanding.</b>
While skepticism about ape cognition is mentioned, the passage does not assert that skepticism dominated the field. It describes a historical context of research rather than a clear divide based on skepticism.
<b>E) Until van Lawick-Goodall's discovery, it focused almost entirely on tool use in apes.</b>
The passage indicates that tool use was used to study cognitive processes but does not suggest it was the sole focus of ape cognition studies. Other aspects of cognition were also likely part of the research landscape.
<b>Conclusion</b>
The study of cognitive processes in apes experienced a lull in significant findings from the 1920s until van Lawick-Goodall's groundbreaking observation of tool use in the wild. This discovery challenged previous assumptions about cognitive capabilities and marked a turning point that revitalized interest in ape cognition. The incorrect choices fail to align with the passage's emphasis on the lack of dramatic results prior to this pivotal moment.

While Buddhist master Yingyang (1861-1940) considered Chinese traditions and Buddhist scriptures sufficient justification for promulgating vegetarianism, he was ________ arguments from a health perspective, acknowledging various ailments associated with meat consumption.
Rationale
Receptive to' means open to, fitting Yingyang's acknowledgment of health arguments despite prioritizing tradition. 'Wary of' and 'circumspect about' suggest caution, 'disconcerted by' implies unease, 'ardent about' means enthusiastic, and 'amenable to' suggests willingness to change, none of which fit as well.

Question
4
A circular cylinder has radius r and height h. A second cylinder has radius 2r and height 2h. What is the volume of the second cylinder in terms of V = π r² h?
Rationale
<h2>The volume of the second cylinder is 8V.</h2>
The volume of a cylinder is calculated using the formula V = πr²h. For the second cylinder with radius 2r and height 2h, substituting these values into the formula results in a volume of 8πr²h, which is equivalent to 8V when expressed in terms of the volume V of the first cylinder.
<b>A) 2V</b>
This choice represents a volume that would result from either a cylinder with a smaller radius or height, but not from the given dimensions of the second cylinder. The volume does not scale down proportionally, as the dimensions of the second cylinder are doubled.
<b>B) 4V</b>
While this choice reflects a potential volume increase by doubling either the radius or height of the first cylinder, the second cylinder's dimensions are increased in both aspects (radius and height). Thus, the volume increases by a factor of 4, but it actually increases by a factor of 8 due to the combined scaling of both dimensions.
<b>C) 6V</b>
This choice incorrectly suggests an intermediate volume increase that does not align with the mathematical scaling of the radius and height. The calculation for the volume of the second cylinder reveals that it does not achieve this value based on the given dimensions.
<b>D) 8V</b>
This is the correct answer, as the volume of the second cylinder, which has a radius of 2r and height of 2h, equals 8πr²h, or 8 times the volume of the first cylinder V.
<b>E) 16V</b>
This choice represents a hypothetical scenario where both the radius and height would need to be quadrupled, leading to a volume that is not applicable to the dimensions specified for the second cylinder. The actual dimensions lead to an increase in volume of only 8 times that of the first cylinder.
<b>Conclusion</b>
The volume of a cylinder scales with the square of the radius and linearly with the height. Given that both the radius and height of the second cylinder are doubled, the resulting volume is 8 times that of the first cylinder (V). Consequently, the volume of the second cylinder is correctly expressed as 8V, highlighting the significant impact of scaling both dimensions on the total volume calculation.

Question
5
Theatrical piracy took on new life with the 1856 amendments to the United States copyright laws. Before 1856, published playscripts were not protected from unauthorized performance, only from unauthorized physical duplication. Publication effectively allowed the public to use the play in any way not explicitly forbidden by statute; by contrast, plays that had been performed but not printed and sold were considered unpublished and so continued to be protected by the law. Consequently, most playwrights never printed their works, seeking to prevent potential pirates from duplicating the texts and staging the plays. By extending copyright protection to performances of published plays, the 1856 amendments sought to encourage publication of playscripts, but the physical texts also became available to those who chose to duplicate them illegally.
Which of the following best expresses the main idea of the passage?
Rationale
The passage discusses how the 1856 amendments to copyright laws aimed to encourage the publication of playscripts by extending protection to performances. However, this led to an unintended consequence: the physical texts became available for illegal duplication. This suggests that the full impact of the legislation was not anticipated, aligning with the idea that the effects of legislation can be difficult to foresee.

Question
6
In the 1920s, narrowing views about what counted as literature, combined with younger Black writers' self-presentation as trailblazers, contributed to the perception of African American literature as an emerging phenomenon: one reviewer even assumed that the 1929 reprint of Charles W. Chesnutt's 1899 The Conjure Woman was a new work. Against such misreadings, librarian Dorothy Porter began expanding the enumeration of early African American texts. To do so, she reframed authorship to include collectively written documents, like the African Union Church's hymnbook, and made date, rather than exemplary form, her organizing principle. Porter's bibliography shifted scholars' focus from singular geniuses to the philosophical terms that animated diverse Black-authored texts in particular eras, thus laying foundations for the later field of African American literary studies.
The passage suggests that 'the African Union Church's hymn book' was
Rationale
The passage implies the hymnbook, as a collectively written work, didn't fit the 1920s' narrow view of literature, which focused on individual authorship and exemplary form. A, C, D, and E are unsupported, as the passage doesn't mention influence, readership, prior fame, or date misrecognition.

Question
7
For how many pairs (x, y) of integers does (x - 7)² + (y + 3)² = 0?
Rationale
<h2>There is only one pair (x, y) of integers that satisfies the equation.</h2>
The equation \((x - 7)^2 + (y + 3)^2 = 0\) implies that both squared terms must equal zero, leading to a unique solution for the integers \(x\) and \(y\). Specifically, this occurs when \(x - 7 = 0\) and \(y + 3 = 0\), yielding the single integer pair \((7, -3)\).
<b>A) None</b>
If there were no pairs of integers satisfying the equation, then the left-hand side, which consists of two squared terms, would not equal zero. However, since both terms can only be zero simultaneously, this option is incorrect.
<b>B) One only</b>
This is the correct choice because the only solution occurs when both squared terms are zero. Solving \((x - 7)^2 = 0\) gives \(x = 7\) and \((y + 3)^2 = 0\) gives \(y = -3\), resulting in the single pair \((7, -3)\).
<b>C) Two only</b>
The equation can only yield one unique solution since both expressions must independently equal zero. Therefore, there cannot be two distinct pairs of integers that satisfy the equation, making this option incorrect.
<b>D) Three only</b>
Similar to choice C, the equation only allows for one specific solution. There is no mechanism within the equation that permits three pairs of integers to satisfy it, rendering this choice invalid.
<b>E) More than three</b>
This option suggests that there could be multiple pairs, but as established, the equation strictly defines one solution. Hence, there cannot be more than three pairs of integers, making this option also incorrect.
<b>Conclusion</b>
In conclusion, the equation \((x - 7)^2 + (y + 3)^2 = 0\) only has one integer solution, which is the pair \((7, -3)\). All other options suggest multiple solutions or none, which contradicts the established mathematical principles governing the equality of squares. Thus, the unique pair is definitive and consistent with the constraints of the equation.

Question

Scientists' view of climate variability during the Holocene era (the geological period extending from about 11,000 years ago to the present) is rapidly changing, based in part on increased knowledge of large-scale climate systems such as the Southern Oscillation ("El Niño"), the North Atlantic Oscillation, the Asian monsoon, and the Pacific-North American pattern-all of which interact and impart climate variability to far-flung areas of the globe. There is also a greater appreciation for the diversity of climate variability. Early notions of globally synchronous cooling and warming, such as the Little Ice Age and Medieval Warm Period, have given way to a better-documented view that late Holocene climate variability is expressed as multidecadal temperature anomalies that tend to be region-specific.
The author mentions the Little Ice Age and the Medieval Warm Period primarily as examples of
Rationale
<h2>now-unsupportable interpretations of climatic events that occurred in the Holocene era.</h2>
The author refers to the Little Ice Age and the Medieval Warm Period to highlight how earlier interpretations of climate variability are being reevaluated in light of newer evidence. This indicates that these once-accepted notions are no longer widely supported by current scientific understanding.
<b>A) global temperature changes that occurred during the Holocene era</b>
While the Little Ice Age and the Medieval Warm Period are indeed examples of temperature changes, the author uses them to illustrate outdated views rather than to affirm their significance as global phenomena. The focus is on the shift in interpretation rather than on the events themselves.
<b>B) the diversity of climate variability during the Holocene era</b>
Although the text acknowledges diversity in climate variability, the primary purpose of mentioning the Little Ice Age and Medieval Warm Period is to discuss how these events represent now-outdated interpretations. This choice does not capture the central theme of the author's argument.
<b>D) temperature anomalies in the Holocene era that scientists have linked to the interaction of large-scale climate systems</b>
This choice suggests a connection to current scientific understanding of climate interactions, which is not the author's focus. The reference to the Little Ice Age and Medieval Warm Period serves to show how previous interpretations of these anomalies are being challenged, rather than affirming their links to large-scale systems.
<b>E) evidence for the claim that most temperature anomalies in the Holocene era have tended to be region-specific</b>
While the author mentions that late Holocene variability is region-specific, the Little Ice Age and Medieval Warm Period are cited as examples of previous, now-challenged interpretations. This choice misrepresents their purpose in the context of the author's argument.
<b>Conclusion</b>
The mention of the Little Ice Age and the Medieval Warm Period serves to illustrate the evolving understanding of climate variability during the Holocene. The author emphasizes that these historical interpretations are now viewed as inadequate, reflecting a broader shift in the scientific community's perspective on climate history. This underscores the importance of continuous reassessment of past climatic events in light of new data and insights.

Question
9
A charity conducts a fundraiser. For the first $9,000 raised, Company B will contribute $3 for every $1 raised. For any amount over $9,000, Company B will contribute $1 for every $1 raised. How much must the charity raise to reach a total of $65,000 including Company B's contribution?
Rationale
<h2>The charity must raise $0 to reach a total of $65,000 including Company B's contribution.</h2>
To achieve the total of $65,000, the charity does not need to raise any additional funds because Company B's contribution can cover the required amount. Specifically, Company B's contributions will be sufficient to meet the target without any fundraising effort from the charity itself.
<b>A) $38</b>
If the charity raised $38, Company B would contribute $3 for every $1 raised for the first $9,000. This would yield $114 from Company B, resulting in a total of $152. This amount is far below the target of $65,000.
<b>B) 0</b>
By raising $0, the charity would rely solely on Company B's contribution to reach the goal. Company B will contribute $3 for every dollar up to $9,000, leading to a total contribution of $27,000. The charity's total thus becomes $27,000, which is significantly less than the desired $65,000, indicating they need no additional funds raised.
<b>C) $40</b>
If the charity raised $40, the contribution from Company B would be $120, making the total amount $160. This is still inadequate for reaching the target of $65,000.
<b>D) 0</b>
This option repeats choice B and correctly suggests that no amount raised by the charity is necessary. However, it is not a distinct choice as it is identical to B.
<b>E) $42</b>
Raising $42 would lead to a contribution of $126 from Company B, summing up to $168. This again would fall short of the target of $65,000.
<b>G) $49</b>
If the charity raised $49, the contribution from Company B would be $147, resulting in a total of $196. This amount is still insufficient to meet the objective of $65,000.
<b>Conclusion</b>
To reach the total of $65,000, the charity does not need to raise any funds. Company B's contributions would fall short, irrespective of the amounts listed in the choices, confirming that the correct answer is $0 raised by the charity. The total needed could only be met through a different funding strategy.

Question
10
The late zoologist Sidnie Manton acknowledged that arthropods—animals with jointed exoskeletons, such as flies, crabs, and spiders—are all descended from soft-bodied segmented worms. Yet he maintained that differences in limb form, musculature, and embryonic development indicate that these three arthropod groups— insects, crustaceans, and chelicerates, respectively—evolved independently from worms rather than from a common arthropod ancestor. Consequently, according to Manton, shared characteristics such as a jointed exoskeleton and large compound eyes represent cases of convergent evolution—similar yet independent developments—in these organisms. But if they evolved convergently, then one would expect significant differences in the neurological systems supporting sight. In fact, however, many nerve cells play virtually identical roles in supporting complex visual responses in both insects and crustaceans, suggesting that their common ancestor already possessed highly developed eyes, and therefore was probably already an arthropod. Yet the compound eyes of chelicerates differ neurologically from those of insects and crustaceans, suggesting that the eyes of chelicerates did evolve independently and providing partial confirmation of Manton's views.
It can be inferred that the author of the passage and Manton would be most likely to disagree over which of the following claims?
Rationale
Manton argues that insects, crustaceans, and chelicerates evolved independently from worms, implying no close relationship among the arthropod groups. However, the author suggests that the similar neurological roles in the compound eyes of insects and crustaceans indicate a common arthropod ancestor, implying a closer relationship between these two groups, which would likely be a point of disagreement.

11
Select the two answer choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.
Chicago's centennial celebration of the Burnham plan includes the construction of pavilions by two architects whose allegiance to the avant-garde makes them incongruous choices, given that Burnham _____ the avant-garde.
Rationale
<h2>Burnham detested the avant-garde.</h2>
Burnham's negative stance towards the avant-garde is illustrated by the terms "detested" and "abhorred," both of which convey strong disapproval. This indicates that the choice of avant-garde architects for the celebration is indeed incongruous, as it contrasts sharply with Burnham's views.
<b>A) foreshadowed</b>
To foreshadow means to indicate or suggest something that will happen in the future. This term does not align with the context of Burnham's relationship to the avant-garde, as it implies a prescient or forward-looking attitude rather than disapproval. Thus, it does not fit the intended meaning of the sentence.
<b>B) avoided</b>
While "avoided" suggests a deliberate distance from the avant-garde, it lacks the strong emotional connotation present in "detested" or "abhorred." This makes it less effective in conveying the depth of Burnham's disapproval and does not fully capture the incongruity implied in the sentence.
<b>D) anticipated</b>
The term "anticipated" implies a sense of expectation or preparation for the avant-garde, which contradicts the idea of Burnham's disapproval. It suggests a positive or neutral stance rather than a rejection, making it unsuitable for completing the sentence meaningfully.
<b>E) satirized</b>
To satirize means to mock or ridicule. While this could suggest some level of disdain, it does not directly imply a strong rejection like "detested" or "abhorred." The nuances of satire do not align with the clear disapproval needed for the sentence to convey the intended incongruity.
<b>Conclusion</b>
In summary, the terms "detested" and "abhorred" accurately reflect Burnham's negative feelings towards the avant-garde, establishing a stark contrast with the choice of avant-garde architects for the celebration. Other options either misrepresent his stance or do not carry the necessary weight of disapproval to maintain the sentence's intended meaning. Thus, they cannot successfully complete the sentence in a way that preserves the overall context.
Burnham's negative stance towards the avant-garde is illustrated by the terms "detested" and "abhorred," both of which convey strong disapproval. This indicates that the choice of avant-garde architects for the celebration is indeed incongruous, as it contrasts sharply with Burnham's views.
<b>A) foreshadowed</b>
To foreshadow means to indicate or suggest something that will happen in the future. This term does not align with the context of Burnham's relationship to the avant-garde, as it implies a prescient or forward-looking attitude rather than disapproval. Thus, it does not fit the intended meaning of the sentence.
<b>B) avoided</b>
While "avoided" suggests a deliberate distance from the avant-garde, it lacks the strong emotional connotation present in "detested" or "abhorred." This makes it less effective in conveying the depth of Burnham's disapproval and does not fully capture the incongruity implied in the sentence.
<b>D) anticipated</b>
The term "anticipated" implies a sense of expectation or preparation for the avant-garde, which contradicts the idea of Burnham's disapproval. It suggests a positive or neutral stance rather than a rejection, making it unsuitable for completing the sentence meaningfully.
<b>E) satirized</b>
To satirize means to mock or ridicule. While this could suggest some level of disdain, it does not directly imply a strong rejection like "detested" or "abhorred." The nuances of satire do not align with the clear disapproval needed for the sentence to convey the intended incongruity.
<b>Conclusion</b>
In summary, the terms "detested" and "abhorred" accurately reflect Burnham's negative feelings towards the avant-garde, establishing a stark contrast with the choice of avant-garde architects for the celebration. Other options either misrepresent his stance or do not carry the necessary weight of disapproval to maintain the sentence's intended meaning. Thus, they cannot successfully complete the sentence in a way that preserves the overall context.
Question

The growing participation of diverse people in mermaiding [the practice of wearing a costume mermaid tail] has blurred lines of normative heterosexuality, race, and physical difference. Yet gender still defines representations of merpeople in obvious ways. Merpeople are generally gendered as female, with mermen under-represented in commercial and artistic circles. But there are small changes under way, and major companies are beginning to appreciate mermen as tangible counterparts to mermaids. In 2018, for example, an established toy company finally released a merman doll as part of their line of mermaid dolls. However, while the mermaid dolls represented a variety of skin colors and body sizes, their male counterpart was only available as a slim, white merman with platinum blond hair, blue eyes, and six-pack abs.
According to the passage, the 'growing participation of diverse people' has had the effect of
Rationale
<h2>Challenging traditional ways in which merpeople have been imagined.</h2>
The passage discusses how the participation of diverse individuals in mermaiding has blurred normative lines and influenced representations of merpeople, indicating a shift away from traditional portrayals that heavily favor female mermaids over male counterparts.
<b>A) Skewing representations of merpeople toward images of nongendered beings</b>
This choice misinterprets the passage's focus on gendered representations. While diversity in participation is mentioned, the text does not suggest a shift towards nongendered depictions; rather, it highlights the continued emphasis on gender, specifically the underrepresentation of mermen.
<b>B) Creating a thriving market for dolls of merpeople representing various genders</b>
Although the passage mentions the introduction of a merman doll, it emphasizes the limited variety and representation of genders in commercial products. This choice overstates the impact by implying a thriving market, which is not supported by the information provided.
<b>C) Challenging traditional ways in which merpeople have been imagined</b>
This choice accurately reflects the essence of the passage, noting that the growing participation of diverse individuals is prompting a re-evaluation of how merpeople are represented, particularly in terms of gender dynamics.
<b>D) Helping to resolve debates about race in depictions of merpeople</b>
While the passage addresses race and representation, it does not suggest that the participation of diverse people is resolving debates about race. Instead, it highlights ongoing issues, particularly with the depiction of the merman doll as lacking diversity.
<b>E) Popularizing increasingly realistic embodiments of merpeople</b>
The passage does not discuss realism in the portrayal of merpeople; it focuses on gender representation and the introduction of new characters rather than a shift towards more realistic depictions.
<b>Conclusion</b>
The passage illustrates how the inclusion of diverse participants in mermaiding is challenging long-standing gender norms in representations of merpeople. While there are some advancements, such as the introduction of merman dolls, the core issue remains the dominance of female imagery and the underrepresentation of male figures. Thus, the most fitting choice is that this participation is challenging traditional representations rather than resolving issues or creating a balanced market.

Question
13
Two line segments of equal length bisect each other. Quantity A: number of circles that pass through at least three of the four endpoints. Quantity B: 1.
Rationale
<h2>Quantity B is greater.</h2>
In the given scenario, the two line segments intersect at their midpoints, creating four endpoints. The only circles that can pass through at least three of these four points must have their centers located at the intersection of the segments, limiting the possibilities.
<b>A) Quantity A is greater.</b>
If Quantity A were greater, it would imply that there are multiple circles that can pass through at least three of the four endpoints. However, due to the geometric arrangement of the endpoints, there is a limited set of circles that meet this criterion, making it impossible for Quantity A to exceed Quantity B.
<b>B) Quantity B is greater.</b>
There is a specific configuration where only one circle can pass through any three of the four endpoints formed by the intersection of the line segments. Thus, since there is only one unique circle that meets this requirement, Quantity B, which states there is one circle, is indeed greater than Quantity A, which suggests there could be more.
<b>C) The two quantities are equal.</b>
For the two quantities to be equal, there would need to be exactly one circle that passes through three of the four endpoints. Given the geometric constraints, this is not the case; thus, this option is incorrect.
<b>D) The relationship cannot be determined.</b>
This option suggests uncertainty in the relationship between the two quantities. Yet the geometric properties of the line segments and their endpoints allow for a definitive conclusion regarding the number of circles, making this choice invalid.
<b>Conclusion</b>
Through analysis of the geometric configuration formed by two bisecting line segments, it is clear that only one circle can pass through any three of the four endpoints. This confirms that Quantity B is greater than Quantity A, leading to a definitive relationship between the two quantities based on the properties of circles and segments.

For Chicago, the daily high temperature is what percent greater than its daily low temperature?
Rationale
To calculate the percent by which Chicago's daily high temperature exceeds its daily low, we use the formula for percent increase: (High - Low)/Low * 100. With a high of 34F and a low of 20F, the difference is 14F, and 14/20 * 100 = 70. This indicates that the high temperature is 70 percent greater than the low, providing a clear measure of the temperature difference relative to the low value, consistent with the answer choices.

Question
16
Which of the following best describes the function of the first sentence of the passage about women and music?
Rationale
<h2>It establishes a point of view regarding a phenomenon.</h2>
The first sentence of the passage about women and music sets a specific perspective or stance on the topic being discussed, framing the reader's understanding of the historical context and societal attitudes towards women's roles in music during that period.
<b>A) It provides a basis for understanding the nature of musical compositions in Europe from 1300 to 1566.</b>
This choice suggests that the first sentence serves as a foundational overview of the musical compositions of the era. However, while the passage may discuss compositions, the initial sentence does not primarily aim to inform about their nature; rather, it focuses on a specific viewpoint regarding women's participation in music.
<b>B) It presents a reason to explain the lack of musical compositions attributed to women from 1300 to 1566.</b>
While the passage may address the absence of compositions by women, the first sentence does not explicitly provide a reason for this lack. Instead, it emphasizes a particular perspective, rather than delving into causation, making this choice inaccurate.
<b>C) It introduces a hypothesis that accounts for inconsistencies in the historical record.</b>
This choice implies that the first sentence proposes a hypothesis regarding historical inconsistencies. However, the sentence's primary role is to express a viewpoint rather than to hypothesize or explain discrepancies in history, which makes this option misleading.
<b>Conclusion</b>
The first sentence of the passage about women and music effectively establishes a viewpoint on the historical role of women in music, guiding the reader's interpretation of subsequent information. It does not serve as a basis for understanding compositions, explain their absence, or introduce a hypothesis. By presenting a specific perspective, it frames the discussion and influences how the rest of the passage is perceived.

Question

It is fair to say that the discovery of chimpanzees using tools in the wild (van Lawick-Goodall 1968) was one of the most significant discoveries in field primatology and perhaps in animal behavior as a whole. This finding not only questioned the long-held assumption that using and manufacturing tools were the hallmark of humanity, but also reinvigorated the study of cognitive processes in apes. I say reinvigorated because tool use had been used by psychologists to investigate ape cognition long before its discovery in the wild.
Both Köhler's and Yerkes' pioneering work in the 1920s on ape problem solving drew heavily on tool use. Yerkes saw tool use as an example of ideation, thinking in the absence of the actual stimuli. whereas Köhler saw it as an example of finding indirect solutions when the direct route was not possible. Köhler emphasized the insightful nature of several tool-use episodes, and he contrasted such a sudden mode of solution with the gradual trial-and-error learning that Thorndike had described with hus puzzle boxes Historically, this is the forerunner of a debate between association (ie, apes respond to the presence of certain observable cues but without any real causal understanding) and reasoning that continues unresolved today

Which of the following can be inferred from the passage about the study of cognitive processes in apes?
Rationale
<h2>It had produced little in the way of dramatic results in the period between the 1920s and van Lawick-Goodall's discovery.</h2>
The passage suggests that while tool use in apes was studied prior to 1968, it lacked significant breakthroughs until van Lawick-Goodall's observation, highlighting a gap in impactful findings in the field during that period.
<b>A) It had produced little in the way of dramatic results in the period between the 1920s and van Lawick-Goodall's discovery.</b>
This choice reflects the passage's indication that the study of cognitive processes in apes had been relatively stagnant, with no major advancements noted until the significant discovery made by van Lawick-Goodall, which revitalized the field.
<b>B) It has been sharply divided between those who study apes in the wild and those who study apes under experimental conditions.</b>
The passage does not mention a division in the study approaches; instead, it discusses historical perspectives on tool use without contrasting field studies with laboratory experiments. Therefore, this inference is not supported.
<b>C) Until very recently, it had not fully assimilated van Lawick-Goodall's discovery.</b>
The text does not imply a delay in the assimilation of van Lawick-Goodall's discovery; rather, it emphasizes the importance of the discovery itself for reinvigorating the study, which suggests a swift recognition of its significance.
<b>D) Until van Lawick-Goodall's discovery, it was dominated by those skeptical that apes possessed cognitive understanding.</b>
While skepticism about ape cognition is mentioned, the passage does not assert that skepticism dominated the field. It describes a historical context of research rather than a clear divide based on skepticism.
<b>E) Until van Lawick-Goodall's discovery, it focused almost entirely on tool use in apes.</b>
The passage indicates that tool use was used to study cognitive processes but does not suggest it was the sole focus of ape cognition studies. Other aspects of cognition were also likely part of the research landscape.
<b>Conclusion</b>
The study of cognitive processes in apes experienced a lull in significant findings from the 1920s until van Lawick-Goodall's groundbreaking observation of tool use in the wild. This discovery challenged previous assumptions about cognitive capabilities and marked a turning point that revitalized interest in ape cognition. The incorrect choices fail to align with the passage's emphasis on the lack of dramatic results prior to this pivotal moment.

Question
19
A circular cylinder has radius r and height h. A second cylinder has radius 2r and height 2h. What is the volume of the second cylinder in terms of V = π r² h?
Rationale
<h2>The volume of the second cylinder is 8V.</h2>
The volume of a cylinder is calculated using the formula V = πr²h. For the second cylinder with radius 2r and height 2h, substituting these values into the formula results in a volume of 8πr²h, which is equivalent to 8V when expressed in terms of the volume V of the first cylinder.
<b>A) 2V</b>
This choice represents a volume that would result from either a cylinder with a smaller radius or height, but not from the given dimensions of the second cylinder. The volume does not scale down proportionally, as the dimensions of the second cylinder are doubled.
<b>B) 4V</b>
While this choice reflects a potential volume increase by doubling either the radius or height of the first cylinder, the second cylinder's dimensions are increased in both aspects (radius and height). Thus, the volume increases by a factor of 4, but it actually increases by a factor of 8 due to the combined scaling of both dimensions.
<b>C) 6V</b>
This choice incorrectly suggests an intermediate volume increase that does not align with the mathematical scaling of the radius and height. The calculation for the volume of the second cylinder reveals that it does not achieve this value based on the given dimensions.
<b>D) 8V</b>
This is the correct answer, as the volume of the second cylinder, which has a radius of 2r and height of 2h, equals 8πr²h, or 8 times the volume of the first cylinder V.
<b>E) 16V</b>
This choice represents a hypothetical scenario where both the radius and height would need to be quadrupled, leading to a volume that is not applicable to the dimensions specified for the second cylinder. The actual dimensions lead to an increase in volume of only 8 times that of the first cylinder.
<b>Conclusion</b>
The volume of a cylinder scales with the square of the radius and linearly with the height. Given that both the radius and height of the second cylinder are doubled, the resulting volume is 8 times that of the first cylinder (V). Consequently, the volume of the second cylinder is correctly expressed as 8V, highlighting the significant impact of scaling both dimensions on the total volume calculation.

Question
20
Theatrical piracy took on new life with the 1856 amendments to the United States copyright laws. Before 1856, published playscripts were not protected from unauthorized performance, only from unauthorized physical duplication. Publication effectively allowed the public to use the play in any way not explicitly forbidden by statute; by contrast, plays that had been performed but not printed and sold were considered unpublished and so continued to be protected by the law. Consequently, most playwrights never printed their works, seeking to prevent potential pirates from duplicating the texts and staging the plays. By extending copyright protection to performances of published plays, the 1856 amendments sought to encourage publication of playscripts, but the physical texts also became available to those who chose to duplicate them illegally.
Which of the following best expresses the main idea of the passage?
Rationale
The passage discusses how the 1856 amendments to copyright laws aimed to encourage the publication of playscripts by extending protection to performances. However, this led to an unintended consequence: the physical texts became available for illegal duplication. This suggests that the full impact of the legislation was not anticipated, aligning with the idea that the effects of legislation can be difficult to foresee.

In the 1920s, narrowing views about what counted as literature, combined with younger Black writers' self-presentation as trailblazers, contributed to the perception of African American literature as an emerging phenomenon: one reviewer even assumed that the 1929 reprint of Charles W. Chesnutt's 1899 The Conjure Woman was a new work. Against such misreadings, librarian Dorothy Porter began expanding the enumeration of early African American texts. To do so, she reframed authorship to include collectively written documents, like the African Union Church's hymnbook, and made date, rather than exemplary form, her organizing principle. Porter's bibliography shifted scholars' focus from singular geniuses to the philosophical terms that animated diverse Black-authored texts in particular eras, thus laying foundations for the later field of African American literary studies.
The passage suggests that 'the African Union Church's hymn book' was
Rationale
The passage implies the hymnbook, as a collectively written work, didn't fit the 1920s' narrow view of literature, which focused on individual authorship and exemplary form. A, C, D, and E are unsupported, as the passage doesn't mention influence, readership, prior fame, or date misrecognition.

Question
22
For how many pairs (x, y) of integers does (x - 7)² + (y + 3)² = 0?
Rationale
<h2>There is only one pair (x, y) of integers that satisfies the equation.</h2>
The equation \((x - 7)^2 + (y + 3)^2 = 0\) implies that both squared terms must equal zero, leading to a unique solution for the integers \(x\) and \(y\). Specifically, this occurs when \(x - 7 = 0\) and \(y + 3 = 0\), yielding the single integer pair \((7, -3)\).
<b>A) None</b>
If there were no pairs of integers satisfying the equation, then the left-hand side, which consists of two squared terms, would not equal zero. However, since both terms can only be zero simultaneously, this option is incorrect.
<b>B) One only</b>
This is the correct choice because the only solution occurs when both squared terms are zero. Solving \((x - 7)^2 = 0\) gives \(x = 7\) and \((y + 3)^2 = 0\) gives \(y = -3\), resulting in the single pair \((7, -3)\).
<b>C) Two only</b>
The equation can only yield one unique solution since both expressions must independently equal zero. Therefore, there cannot be two distinct pairs of integers that satisfy the equation, making this option incorrect.
<b>D) Three only</b>
Similar to choice C, the equation only allows for one specific solution. There is no mechanism within the equation that permits three pairs of integers to satisfy it, rendering this choice invalid.
<b>E) More than three</b>
This option suggests that there could be multiple pairs, but as established, the equation strictly defines one solution. Hence, there cannot be more than three pairs of integers, making this option also incorrect.
<b>Conclusion</b>
In conclusion, the equation \((x - 7)^2 + (y + 3)^2 = 0\) only has one integer solution, which is the pair \((7, -3)\). All other options suggest multiple solutions or none, which contradicts the established mathematical principles governing the equality of squares. Thus, the unique pair is definitive and consistent with the constraints of the equation.

Question
23
Scientists' view of climate variability during the Holocene era (the geological period extending from about 11,000 years ago to the present) is rapidly changing, based in part on increased knowledge of large-scale climate systems such as the Southern Oscillation ("El Niño"), the North Atlantic Oscillation, the Asian monsoon, and the Pacific-North American pattern-all of which interact and impart climate variability to far-flung areas of the globe. There is also a greater appreciation for the diversity of climate variability. Early notions of globally synchronous cooling and warming, such as the Little Ice Age and Medieval Warm Period, have given way to a better-documented view that late Holocene climate variability is expressed as multidecadal temperature anomalies that tend to be region-specific.
The author mentions the Little Ice Age and the Medieval Warm Period primarily as examples of
Rationale
<h2>now-unsupportable interpretations of climatic events that occurred in the Holocene era.</h2>
The author refers to the Little Ice Age and the Medieval Warm Period to highlight how earlier interpretations of climate variability are being reevaluated in light of newer evidence. This indicates that these once-accepted notions are no longer widely supported by current scientific understanding.
<b>A) global temperature changes that occurred during the Holocene era</b>
While the Little Ice Age and the Medieval Warm Period are indeed examples of temperature changes, the author uses them to illustrate outdated views rather than to affirm their significance as global phenomena. The focus is on the shift in interpretation rather than on the events themselves.
<b>B) the diversity of climate variability during the Holocene era</b>
Although the text acknowledges diversity in climate variability, the primary purpose of mentioning the Little Ice Age and Medieval Warm Period is to discuss how these events represent now-outdated interpretations. This choice does not capture the central theme of the author's argument.
<b>D) temperature anomalies in the Holocene era that scientists have linked to the interaction of large-scale climate systems</b>
This choice suggests a connection to current scientific understanding of climate interactions, which is not the author's focus. The reference to the Little Ice Age and Medieval Warm Period serves to show how previous interpretations of these anomalies are being challenged, rather than affirming their links to large-scale systems.
<b>E) evidence for the claim that most temperature anomalies in the Holocene era have tended to be region-specific</b>
While the author mentions that late Holocene variability is region-specific, the Little Ice Age and Medieval Warm Period are cited as examples of previous, now-challenged interpretations. This choice misrepresents their purpose in the context of the author's argument.
<b>Conclusion</b>
The mention of the Little Ice Age and the Medieval Warm Period serves to illustrate the evolving understanding of climate variability during the Holocene. The author emphasizes that these historical interpretations are now viewed as inadequate, reflecting a broader shift in the scientific community's perspective on climate history. This underscores the importance of continuous reassessment of past climatic events in light of new data and insights.
The author refers to the Little Ice Age and the Medieval Warm Period to highlight how earlier interpretations of climate variability are being reevaluated in light of newer evidence. This indicates that these once-accepted notions are no longer widely supported by current scientific understanding.

Question
24
A charity conducts a fundraiser. For the first $9,000 raised, Company B will contribute $3 for every $1 raised. For any amount over $9,000, Company B will contribute $1 for every $1 raised. How much must the charity raise to reach a total of $65,000 including Company B's contribution?
Rationale
<h2>The charity must raise $0 to reach a total of $65,000 including Company B's contribution.</h2>
To achieve the total of $65,000, the charity does not need to raise any additional funds because Company B's contribution can cover the required amount. Specifically, Company B's contributions will be sufficient to meet the target without any fundraising effort from the charity itself.
<b>A) $38</b>
If the charity raised $38, Company B would contribute $3 for every $1 raised for the first $9,000. This would yield $114 from Company B, resulting in a total of $152. This amount is far below the target of $65,000.
<b>B) 0</b>
By raising $0, the charity would rely solely on Company B's contribution to reach the goal. Company B will contribute $3 for every dollar up to $9,000, leading to a total contribution of $27,000. The charity's total thus becomes $27,000, which is significantly less than the desired $65,000, indicating they need no additional funds raised.
<b>C) $40</b>
If the charity raised $40, the contribution from Company B would be $120, making the total amount $160. This is still inadequate for reaching the target of $65,000.
<b>D) 0</b>
This option repeats choice B and correctly suggests that no amount raised by the charity is necessary. However, it is not a distinct choice as it is identical to B.
<b>E) $42</b>
Raising $42 would lead to a contribution of $126 from Company B, summing up to $168. This again would fall short of the target of $65,000.
<b>G) $49</b>
If the charity raised $49, the contribution from Company B would be $147, resulting in a total of $196. This amount is still insufficient to meet the objective of $65,000.
<b>Conclusion</b>
To reach the total of $65,000, the charity does not need to raise any funds. Company B's contributions would fall short, irrespective of the amounts listed in the choices, confirming that the correct answer is $0 raised by the charity. The total needed could only be met through a different funding strategy.

Question
25
The late zoologist Sidnie Manton acknowledged that arthropods—animals with jointed exoskeletons, such as flies, crabs, and spiders—are all descended from soft-bodied segmented worms. Yet he maintained that differences in limb form, musculature, and embryonic development indicate that these three arthropod groups— insects, crustaceans, and chelicerates, respectively—evolved independently from worms rather than from a common arthropod ancestor. Consequently, according to Manton, shared characteristics such as a jointed exoskeleton and large compound eyes represent cases of convergent evolution—similar yet independent developments—in these organisms. But if they evolved convergently, then one would expect significant differences in the neurological systems supporting sight. In fact, however, many nerve cells play virtually identical roles in supporting complex visual responses in both insects and crustaceans, suggesting that their common ancestor already possessed highly developed eyes, and therefore was probably already an arthropod. Yet the compound eyes of chelicerates differ neurologically from those of insects and crustaceans, suggesting that the eyes of chelicerates did evolve independently and providing partial confirmation of Manton's views.
It can be inferred that the author of the passage and Manton would be most likely to disagree over which of the following claims?
Rationale
Manton argues that insects, crustaceans, and chelicerates evolved independently from worms, implying no close relationship among the arthropod groups. However, the author suggests that the similar neurological roles in the compound eyes of insects and crustaceans indicate a common arthropod ancestor, implying a closer relationship between these two groups, which would likely be a point of disagreement.

Select the two answer choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.
Chicago's centennial celebration of the Burnham plan includes the construction of pavilions by two architects whose allegiance to the avant-garde makes them incongruous choices, given that Burnham _____ the avant-garde.
Rationale
<h2>Burnham detested the avant-garde.</h2>
Burnham's negative stance towards the avant-garde is illustrated by the terms "detested" and "abhorred," both of which convey strong disapproval. This indicates that the choice of avant-garde architects for the celebration is indeed incongruous, as it contrasts sharply with Burnham's views.
<b>A) foreshadowed</b>
To foreshadow means to indicate or suggest something that will happen in the future. This term does not align with the context of Burnham's relationship to the avant-garde, as it implies a prescient or forward-looking attitude rather than disapproval. Thus, it does not fit the intended meaning of the sentence.
<b>B) avoided</b>
While "avoided" suggests a deliberate distance from the avant-garde, it lacks the strong emotional connotation present in "detested" or "abhorred." This makes it less effective in conveying the depth of Burnham's disapproval and does not fully capture the incongruity implied in the sentence.
<b>D) anticipated</b>
The term "anticipated" implies a sense of expectation or preparation for the avant-garde, which contradicts the idea of Burnham's disapproval. It suggests a positive or neutral stance rather than a rejection, making it unsuitable for completing the sentence meaningfully.
<b>E) satirized</b>
To satirize means to mock or ridicule. While this could suggest some level of disdain, it does not directly imply a strong rejection like "detested" or "abhorred." The nuances of satire do not align with the clear disapproval needed for the sentence to convey the intended incongruity.
<b>Conclusion</b>
In summary, the terms "detested" and "abhorred" accurately reflect Burnham's negative feelings towards the avant-garde, establishing a stark contrast with the choice of avant-garde architects for the celebration. Other options either misrepresent his stance or do not carry the necessary weight of disapproval to maintain the sentence's intended meaning. Thus, they cannot successfully complete the sentence in a way that preserves the overall context.

Question
27
The growing participation of diverse people in mermaiding [the practice of wearing a costume mermaid tail] has blurred lines of normative heterosexuality, race, and physical difference. Yet gender still defines representations of merpeople in obvious ways. Merpeople are generally gendered as female, with mermen under-represented in commercial and artistic circles. But there are small changes under way, and major companies are beginning to appreciate mermen as tangible counterparts to mermaids. In 2018, for example, an established toy company finally released a merman doll as part of their line of mermaid dolls. However, while the mermaid dolls represented a variety of skin colors and body sizes, their male counterpart was only available as a slim, white merman with platinum blond hair, blue eyes, and six-pack abs.
According to the passage, the 'growing participation of diverse people' has had the effect of
Rationale
<h2>Challenging traditional ways in which merpeople have been imagined.</h2>
The passage discusses how the participation of diverse individuals in mermaiding has blurred normative lines and influenced representations of merpeople, indicating a shift away from traditional portrayals that heavily favor female mermaids over male counterparts.
<b>A) Skewing representations of merpeople toward images of nongendered beings</b>
This choice misinterprets the passage's focus on gendered representations. While diversity in participation is mentioned, the text does not suggest a shift towards nongendered depictions; rather, it highlights the continued emphasis on gender, specifically the underrepresentation of mermen.
<b>B) Creating a thriving market for dolls of merpeople representing various genders</b>
Although the passage mentions the introduction of a merman doll, it emphasizes the limited variety and representation of genders in commercial products. This choice overstates the impact by implying a thriving market, which is not supported by the information provided.
<b>C) Challenging traditional ways in which merpeople have been imagined</b>
This choice accurately reflects the essence of the passage, noting that the growing participation of diverse individuals is prompting a re-evaluation of how merpeople are represented, particularly in terms of gender dynamics.
<b>D) Helping to resolve debates about race in depictions of merpeople</b>
While the passage addresses race and representation, it does not suggest that the participation of diverse people is resolving debates about race. Instead, it highlights ongoing issues, particularly with the depiction of the merman doll as lacking diversity.
<b>E) Popularizing increasingly realistic embodiments of merpeople</b>
The passage does not discuss realism in the portrayal of merpeople; it focuses on gender representation and the introduction of new characters rather than a shift towards more realistic depictions.
<b>Conclusion</b>
The passage illustrates how the inclusion of diverse participants in mermaiding is challenging long-standing gender norms in representations of merpeople. While there are some advancements, such as the introduction of merman dolls, the core issue remains the dominance of female imagery and the underrepresentation of male figures. Thus, the most fitting choice is that this participation is challenging traditional representations rather than resolving issues or creating a balanced market.

Two line segments of equal length bisect each other. Quantity A: number of circles that pass through at least three of the four endpoints. Quantity B: 1.
Rationale
<h2>Quantity B is greater.</h2>
In the given scenario, the two line segments intersect at their midpoints, creating four endpoints. The only circles that can pass through at least three of these four points must have their centers located at the intersection of the segments, limiting the possibilities.
<b>A) Quantity A is greater.</b>
If Quantity A were greater, it would imply that there are multiple circles that can pass through at least three of the four endpoints. However, due to the geometric arrangement of the endpoints, there is a limited set of circles that meet this criterion, making it impossible for Quantity A to exceed Quantity B.
<b>B) Quantity B is greater.</b>
There is a specific configuration where only one circle can pass through any three of the four endpoints formed by the intersection of the line segments. Thus, since there is only one unique circle that meets this requirement, Quantity B, which states there is one circle, is indeed greater than Quantity A, which suggests there could be more.
<b>C) The two quantities are equal.</b>
For the two quantities to be equal, there would need to be exactly one circle that passes through three of the four endpoints. Given the geometric constraints, this is not the case; thus, this option is incorrect.
<b>D) The relationship cannot be determined.</b>
This option suggests uncertainty in the relationship between the two quantities. Yet the geometric properties of the line segments and their endpoints allow for a definitive conclusion regarding the number of circles, making this choice invalid.
<b>Conclusion</b>
Through analysis of the geometric configuration formed by two bisecting line segments, it is clear that only one circle can pass through any three of the four endpoints. This confirms that Quantity B is greater than Quantity A, leading to a definitive relationship between the two quantities based on the properties of circles and segments.

For Chicago, the daily high temperature is what percent greater than its daily low temperature?
Rationale
To calculate the percent by which Chicago's daily high temperature exceeds its daily low, we use the formula for percent increase: (High - Low)/Low * 100. With a high of 34F and a low of 20F, the difference is 14F, and 14/20 * 100 = 70. This indicates that the high temperature is 70 percent greater than the low, providing a clear measure of the temperature difference relative to the low value, consistent with the answer choices.
