Passage
(1) Calling someone a rat may be complimentary. (2) In one experiment, University of Chicago neuroscientist Peggy Mason placed 30 pairs of rats in pens. (3) One rat was caged in the middle of the pen, while the other was free to run around. (4) Eventually, 23 of 30 rats liberated their peers by pushing the cage door open with their heads or leaning against the door until it tipped over.
(5) In another experiment, Mason gave rats access to two cages: in one cage was another rat, in the other was a pile of chocolate chips. (6) The rats eating the chocolate themselves. (7) Instead, most of the rodents opened both cages and shared the sweets. (8) "In rat land, that is big." Mason says, claiming that this study is the first to show altruistic behavior in rodents.
(9) Not all scientists agree with the conclusion Mason drew from the experiment, however. (10) The jailbreaking rats might have only been trying to silence their cohorts' distressing alarm calls. (11) Mason counters that the alarm calls from the caged rats were not frequent enough to motivate their peers, but both parties are speculating at this point.
(12) Mason's new study is one of many that are changing how scientists think about empathy and altruism, namely: that such characteristics are not limited to people, as they once thought. (13) It now seems that many animals have evolved instincts to help others.
In context, how should the underlined part of sentence 6 (reproduced below) be revised? The rats eating the chocolate themselves.
- A. would have eaten
- B. could have eaten
- C. had eaten
- D. have eaten
Correct Answer & Rationale
Correct Answer: D
The phrase "the rats eating the chocolate themselves" requires a revision to align with the present tense context of the sentence. Option D, "have eaten," effectively conveys a completed action relevant to the present, indicating that the rats have consumed the chocolate. Option A, "would have eaten," suggests a conditional scenario that does not fit the context. Option B, "could have eaten," implies potentiality rather than a completed action. Option C, "had eaten," indicates a past action that is no longer relevant to the present context. Thus, only option D maintains the intended meaning and tense consistency.

Correct Answer & Rationale
Correct Answer: C
Option C effectively maintains the parallel structure of the list, ensuring clarity and flow. The use of commas before "and" is appropriate in a series with three or more items, adhering to standard punctuation rules. Option A retains the original structure but lacks clarity due to the unnecessary comma after "light." Option B omits the comma before "and," which can lead to confusion in longer lists, making it less clear. Option D incorrectly adds a comma after "and," which is grammatically incorrect and disrupts the flow of the sentence. Thus, C is the most effective choice for clarity and correctness.

Which is the best version of the underlined portion of sentence 13 (reproduced below)?
It might result in fewer trips to the store, which could keep fuel and cut down on pollution
- A. (as it is now)
- B. protect
- C. conserve
- D. support
Correct Answer & Rationale
Correct Answer: C
The phrase "cut down on pollution" suggests reducing waste, making "conserve" the most suitable choice. It aligns with the idea of using fewer resources, such as fuel, to achieve environmental benefits. Option A retains the original wording, which lacks precision and clarity. Option B, "protect," implies safeguarding resources but does not directly convey the idea of reducing usage. Option D, "support," suggests encouragement or assistance, which is not relevant to the context of minimizing trips and their environmental impact. Thus, "conserve" effectively captures the intended meaning of reducing consumption and pollution.

The best placement for sentence 12 within the third paragraph would be
- A. where it is now
- B. before sentence 11
- C. after sentence 13
- D. after sentence 14
Correct Answer & Rationale
Correct Answer: C
Placing sentence 12 after sentence 13 allows for a logical flow of ideas, as it builds on the information presented in the preceding sentences, enhancing coherence. This positioning ensures that the reader receives a complete thought before transitioning to the next point. Option A retains the sentence in its current position, which disrupts the paragraph's flow. Option B places it too early, causing a disconnect with the context of sentence 11. Option D positions it too late, potentially losing the reader's engagement with the preceding content. Thus, option C optimally maintains the paragraph's structure and clarity.

Should sentence 15 (reproduced below) be kept in the fourth paragraph? Actually, there's not much about living here that intimidates me anymore, and I've even gotten used to the noise
- A. Yes, because it is appropriate to the paragraph's purpose of creating a feeling of being in a busy city.
- B. Yes, because it reinforces the paragraph's focus on the narrator's evolving perspective about the city.
- C. No, because it blurs the paragraph's focus on the uncommon experiences the narrator has had in the city

Correct Answer & Rationale
Correct Answer: B
Option B effectively highlights the evolving perspective of the narrator, emphasizing personal growth and adaptation to city life. This aligns with the paragraph’s theme of transformation and acceptance. Option A, while noting the busy city atmosphere, fails to capture the deeper significance of the narrator's emotional journey, which is central to the paragraph’s intent. Option C incorrectly suggests that the sentence detracts from the focus on unique experiences; instead, it complements the narrator's journey by showcasing a shift in perception. Option D misinterprets the relevance of the sentence, as it actually contributes to understanding the challenges faced in adapting to urban life.
