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.

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.

Which is the best version of the underlined portion of sentence 4 (reproduced below)? He knew that he was the first poet to participate in these prestigious ceremonies; therefore, he contemplated which poem would be appropriate for the occasion.
- A. (as it is now)
- B. ceremonies, therefore,
- C. ceremonies, therefore;
- D. ceremonies, therefore
Correct Answer & Rationale
Correct Answer: A
Option A maintains the original structure, effectively connecting the two independent clauses with a semicolon. This punctuation is appropriate as it separates related but distinct ideas: the poet's recognition and his subsequent contemplation. Option B incorrectly uses a comma before "therefore," which fails to properly separate the clauses and creates a comma splice. Option C introduces an unnecessary semicolon before "therefore," which disrupts the flow and is grammatically incorrect since "therefore" is not an independent clause. Option D lacks punctuation after "ceremonies," making it a run-on sentence and confusing the relationship between the ideas.

In context, which would be the most effective way to revise and combine sentences 3 and 4 (reproduced below)? He taught himself to juggle. He could juggle three balls perfectly by the age of six.
- A. to juggle and by the age of six could juggle three balls perfectly.
- B. to juggle: he juggles three balls perfectly by the age of six.
- C. to juggle three balls perfectly; they did it by the age of six.
- D. juggling, and they juggled three balls perfectly by the age of six.
Correct Answer & Rationale
Correct Answer: A
Option A effectively combines the two sentences by maintaining clarity and coherence. It emphasizes the subject's self-taught skill and seamlessly links the action of juggling with the achievement of juggling three balls perfectly by age six. Option B introduces a confusing shift in tense and subject, making it less clear who is performing the action. Option C inaccurately uses "they," which introduces ambiguity about the subject and detracts from the focus on the individual. Option D also employs "they," leading to confusion, and the structure fails to convey the timeline of learning and achievement clearly.

With four recent United States presidents being left-handed Ford, the elder Bush, Clinton and Obama the stigma associated with left-handedness largely vanishing
- A. left-handedness largely vanishing
- B. left-handedness has largely vanished
- C. left-handedness being largely vanished
- D. left-handedness and largely vanished
Correct Answer & Rationale
Correct Answer: B
Option B effectively conveys that left-handedness has significantly decreased in societal stigma. The present perfect tense ("has largely vanished") indicates a change that started in the past and continues to the present, aligning well with the context of the sentence. Option A uses "largely vanishing," which is awkward and suggests an ongoing process rather than a completed change. Option C's "being largely vanished" is grammatically incorrect, as "being" does not fit with the passive construction. Option D incorrectly combines "and" with "largely vanished," creating a fragment that lacks clarity and coherence.
