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, adjusting capitalization as needed, which of the following would most appropriately be inserted at the beginning of sentence 10 (reproduced below)?
The jailbreaking rats might have only been trying to silence their cohorts' distressing alarm calls
It is true that:
- A. It is true that
- B. They point out that
- C. They claim it is obvious that
- D. It appears that
Correct Answer & Rationale
Correct Answer: B
Option B, "They point out that," effectively introduces the sentence by indicating that a specific viewpoint or observation is being made about the jailbreaking rats' behavior. This phrasing suggests a direct reference to a previous argument or evidence, enhancing the clarity of the statement. Option A, "It is true that," is too vague and does not connect to any preceding discussion, making it less effective. Option C, "They claim it is obvious that," implies a level of certainty that may not be warranted, potentially misrepresenting the argument's intent. Option D, "It appears that," introduces ambiguity and weakens the assertiveness needed in this context, making it less suitable than option B.

Which is the best version of the underlined portion of sentence 12 (reproduced below)? 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.
- A. (as it is now)
- B. altruism: namely
- C. altruism, namely,
- D. altruism-namely,
Correct Answer & Rationale
Correct Answer: C
Option C, "altruism, namely," correctly uses a comma before "namely" to set off the phrase that introduces an explanation or clarification. This punctuation aids in the clarity of the sentence, indicating that what follows elaborates on the previous statement. Option A, "as it is now," is incorrect because it does not provide the necessary clarification about altruism, failing to connect the ideas effectively. Option B, "altruism: namely," misuses the colon. A colon typically precedes a list or explanation but is not appropriate here as the phrase does not introduce a list. Option D, "altruism-namely," incorrectly uses a hyphen, which does not convey the intended pause or separation needed for 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

Correct Answer & Rationale
Correct Answer: B

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.

Which change is needed in the fourth paragraph?
- A. In sentence 15, change 'immanent' to 'eminent'
- B. In sentence 15, change 'dual' to 'duel'
- C. In sentence 16, change 'inspire' to 'aspire'
- D. In sentence 17, change 'proceeded' to 'preceded'
Correct Answer & Rationale
Correct Answer: A
Option A is necessary because "immanent" refers to something inherent or existing within, while "eminent" means distinguished or prominent, which fits the context of the paragraph. Option B is incorrect since "dual" refers to two parts, whereas "duel" signifies a contest between two individuals, which does not align with the intended meaning. Option C is not suitable because "inspire" means to motivate, while "aspire" means to aim for something. The original term correctly conveys the intended message. Option D is also wrong; "proceeded" indicates moving forward, while "preceded" means to come before, which is the intended meaning in this context.

Correct Answer & Rationale
Correct Answer: C
Option B effectively combines the sentences by using a relative clause, making it concise and clear. It maintains the original meaning while improving flow. Option A is less effective due to the awkward phrasing "and that’s where," which disrupts the sentence's rhythm and clarity. Option C introduces unnecessary complexity with "where I lived and grew up," making it wordy and repetitive. Option D, while grammatically correct, adds unnecessary phrases like "used to live," which complicate the sentence without enhancing its clarity or brevity. Overall, option B provides the best revision by succinctly merging the ideas.
