Read the following early draft of an essay and then choose the best answer to the question or the best completion of the statement
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.
Where would the following sentence best fit in the passage? The results of two new experiments suggest that rats are surprisingly selfless.
- A. After sentence 1
- B. After sentence 3
- C. After sentence 8
- D. After sentence 11
Correct Answer & Rationale
Correct Answer: C
Placing the sentence after sentence 8 effectively introduces the new findings about rats, enhancing the flow of information regarding their behavior. This position allows for a natural transition into discussing the implications of these experiments. Option A is too early in the passage, as it lacks context for the experiments. Option B, following sentence 3, interrupts the narrative progression and does not align with the preceding content. Option D, after sentence 11, is too late, as it would disrupt the conclusion by introducing new information that should precede it. Thus, option C is the most logical placement.

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.

In context, which of the following is the best version of the underlined portion of sentence 3 (reproduced below)? Dark shadows: streaks of bright light, and, off-balance compositions were all typical of the visual style.
- A. (as it is now)
- B. shadows, streaks of bright light and
- C. shadows, streaks of bright light, and
- D. shadows, streaks of bright light, and,
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 sentence should be deleted because it contains irrelevant information?
- A. Sentence 1
- B. Sentence 6
- C. Sentence 9
- D. Sentence 11
Correct Answer & Rationale
Correct Answer: D
Sentence 11 should be deleted as it introduces information that does not directly support the main topic of the paragraph. It diverges from the core argument, making it less relevant to the overall message. Sentence 1, 6, and 9, on the other hand, provide context or examples that enhance understanding of the main idea. Sentence 1 sets the stage, while sentences 6 and 9 contribute important details that are closely tied to the central theme. Removing sentence 11 helps maintain focus and clarity in the writing, ensuring that all remaining content is pertinent to the discussion.

- D. I'm a country kid from rural Texas, and I used to live on a ranch on the prairie where I grew up.
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.
