According to scientists, the seven separate continents of the world in the far distant past, one vast land mass
- A. the world, in the far distant past
- B. the world, being in the far distant past
- C. the world were, in the far distant past
- D. the world was, in the far distant past
Correct Answer & Rationale
Correct Answer: D
In this sentence, clarity and grammatical accuracy are essential. Option D accurately uses "was" to indicate that the continents once existed as a single land mass in the past, aligning with standard subject-verb agreement. Option A is incomplete, lacking a verb that connects the subject to the predicate. Option B incorrectly uses "being," which does not convey the past tense needed for this context. Option C uses "were," which is incorrect as it implies a plural subject, while "the world" is singular. Thus, D is the only option that correctly reflects the historical context and grammatical structure.

Which version of the underlined portion in sentence 14 (reproduced below) most effectively elaborates on the idea presented at the beginning of the sentence? In spite of his concern over time constraintsâ€â€the occasion was an important oneâ€â€he resolved to compose a relevant tribute.
- A. (as it is now)
- B. the event would be held in the nation's capital!â€â€
- C. only two days until the ceremony!â€â€

Correct Answer & Rationale
Correct Answer: A
Option A maintains the focus on the significance of the occasion while acknowledging the speaker's time constraints, creating a balanced perspective. It emphasizes the importance of the tribute without introducing unrelated details. Option B diverts attention to the location, which, while noteworthy, does not enhance the understanding of the speaker's internal conflict. Option C mentions the urgency but lacks context about the event's significance, making it less effective in elaborating on the initial idea. Option D highlights the audience but shifts focus away from the speaker's concerns, failing to connect back to the tribute's relevance.

Which of the following is the best version of the underlined portion of sentence 3 (reproduced below)? Agricultural activities can disrupt animal's natural habitats.
- A. (as it is now)
- B. animal's natural habitat's.
- C. animals' natural habitats.
- D. animals natural habitats
Correct Answer & Rationale
Correct Answer: C
Option C, "animals' natural habitats," is the best choice because it correctly uses the plural possessive form. Since multiple animals are affected, the apostrophe is placed after "animals" to indicate that the habitats belong to them. Option A retains the original error of using the singular possessive "animal's," which is incorrect when referring to multiple animals. Option B incorrectly adds an unnecessary apostrophe after "habitat," suggesting possession that does not apply here, leading to confusion. Option D lacks the necessary apostrophe to indicate possession, making it grammatically incorrect.

In context, where would the following sentence best be placed? Banana consumption surpassed that of apples only 20 years after they were first introduced to Americans.
- A. After sentence 3
- B. After sentence 4
- C. After sentence 6
- D. After sentence 7
Correct Answer & Rationale
Correct Answer: B
Placing the sentence after sentence 4 provides a logical flow, as it builds on the preceding discussion about the introduction of bananas to Americans and their rising popularity. This context allows readers to understand the significance of the banana's consumption surpassing apples. Option A is too early, as it lacks the necessary context about the introduction of bananas. Option C comes too late, as it may disrupt the narrative flow established earlier. Option D is also inappropriate, as it would place the information after a conclusion, making it feel disconnected from the main discussion.

In context, where would the following sentence best be placed? Because of this model, which gives residents an incentive to protect wildlife, important wildlife populations are increasing at record rates.
- A. After sentence 2
- B. After sentence 4
- C. After sentence 7
- D. After sentence 10
Correct Answer & Rationale
Correct Answer: C
Placing the sentence after sentence 7 is ideal as it follows a discussion about the benefits of the model, directly linking the incentive to the positive outcomes for wildlife populations. This placement emphasizes the cause-and-effect relationship effectively. Option A, after sentence 2, disrupts the flow, as earlier sentences may not yet establish the model's context. Option B, after sentence 4, is too early in the discussion, lacking sufficient background on the model's impact. Option D, after sentence 10, may dilute the sentence's significance, as it would be too far removed from the relevant context, making the connection less impactful.
