Text
Quasars—such as APM 08279+5255, located in the Lynx constellation—are extremely luminous galactic nuclei powered by supermassive black holes, some of which are known to have developed within the first billion years of the formation of the universe. Based on simulations they conducted, astrophysicists Daniel Whalen, Muhammad Latif, and colleagues concluded that these early quasars developed partly as a result of rare convergences of gases in space without the need for ultraviolet backgrounds or other extreme and implausible environmental conditions that models of the early universe have included to account for the presence of these quasars. If this conclusion is correct, it suggests that ______.
Which choice most logically completes the text?
A) future models of the early universe may not need to include conditions that explain early quasars since those quasars may not have actually existed at the time.
B) it may be possible to develop models of the early universe that rest on more credible assumptions than previous models have.
C) factors that previous models of the early universe assumed were necessary for the formation of quasars may have actually been consequences of the formation of quasars.
D) previous models of the early universe may have underemphasized the importance of ultraviolet backgrounds to quasar formation.
▶️ Answer/Explanation
Ans: B
The text explains that early quasars may have formed through rare gas convergences without requiring the extreme conditions previously assumed in models. This suggests that future models could be based on more plausible assumptions. Option B correctly captures this implication, while the other choices either contradict the passage (A, D) or introduce unsupported ideas (C).
Question
In her 2021 article “Throwaway History: Towards a Historiography of Ephemera,” scholar Anne Garner discusses John Johnson (1882–1956), a devoted collector of items intended to be discarded, including bus tickets and campaign pamphlets. Johnson recognized that scholarly institutions considered his expansive collection of ephemera to be worthless—indeed, it wasn’t until 1968, after Johnson’s death, that Oxford University’s Bodleian Library acquired the collection, having grasped the items’ potential value to historians and other researchers. Hence, the example of Johnson serves to ______
Which choice most logically completes the text?
A. demonstrate the difficulties faced by contemporary historians in conducting research at the Bodleian Library without access to ephemera.
B. represent the challenge of incorporating examples of ephemera into the collections of libraries and other scholarly institutions.
C. lend support to arguments by historians and other researchers who continue to assert that ephemera holds no value for scholars.
D. illustrate both the relatively low scholarly regard in which ephemera was once held and the later recognition of ephemera’s possible utility.
▶️Answer/Explanation
Ans. D
Correct Answer: D
Rationale
Choice D is the best answer. Johnson collected “ephemera,” or things that are meant to be thrown away. Scholars thought his collection was worthless to them, then later realized that it was potentially valuable. This suggests that scholars went from disregarding ephemera to recognizing their usefulness. Choice A is incorrect. This inference isn’t supported. The text tells us that the Bodleian Library acquired Johnson’s large collection of ephemera back in 1968, so we can assume that contemporary historians conducting research there do have access to that collection. Choice B is incorrect. This inference isn’t supported. The text tells us that “Oxford University’s Bodleian Library acquired the collection,” but it never suggests that it was a challenge to do so. Choice C is incorrect. This inference isn’t supported. The text actually suggests the opposite: the example of Johnson’s collection lends support to arguments that ephemera does hold value for scholars.
Question
Some businesses believe that when employees are interrupted while doing their work, they experience a decrease in energy and productivity. However, a team led by Harshad Puranik, who studies management, has found that interruptions by colleagues can have a social component that increases employees’ sense of belonging, resulting in greater job satisfaction that benefits employees and employers. Therefore, businesses should recognize that ______
Which choice most logically completes the text?
A. the interpersonal benefits of some interruptions in the workplace may offset the perceived negative effects.
B. in order to maximize productivity, employers should be willing to interrupt employees frequently throughout the day.
C. most employees avoid interrupting colleagues because they don’t appreciate being interrupted themselves.
D. in order to cultivate an ideal workplace environment, interruptions of work should be discouraged.
▶️Answer/Explanation
Ans. A
Correct Answer: A
Rationale
Choice A is the best answer because it most logically completes the text’s discussion of potential benefits of interruptions in the workplace. The text indicates that a common belief in business is that interruptions to working employees decrease energy and productivity levels. However, the text goes on to explain that a research team led by Harshad Puranik has found that there could be a social benefit to these interruptions. Since the team found that workplace interruptions can increase employees’ sense of belonging and job satisfaction, it follows that the interpersonal benefits of some interruptions can offset the perceived negative effects.
Choice B is incorrect. Although the text presents research findings that suggest some workplace interruptions can have a positive effect on employee job satisfaction, no further information is presented to suggest at what frequency these interruptions are ideal. Furthermore, the text doesn’t tie workplace interruptions to increased productivity, but rather links it to social benefits such as sense of belonging. Choice C is incorrect because the text doesn’t address employees’ motives for choosing not to interrupt their colleagues. The text presents research findings that suggest that there are some positive interpersonal effects of workplace interruptions that can increase employee job satisfaction. Choice D is incorrect because asking businesses to discourage workplace interruptions doesn’t follow from the team’s research about the benefits of workplace interruptions, nor does the text describe an ideal work environment. Instead, the text presents research suggesting that there may be positive aspects to workplace interruptions that haven’t previously been considered.
