In context, which of the following is the best way to revise and combine sentences 1 and 2 (reproduced below)? Sauropods, known today as the largest dinosaurs, were long-necked giants. Their fossils have baffled scientists for decades.
- A. The fossils of sauropods, the long-necked giants who are known today as the largest dinosaurs, have baffled scientists for decades.
- B. Sauropods, long-necked giants, are known today as the largest dinosaurs whose fossils have baffled scientists for decades.
- C. Scientists have been baffled for decades by sauropod fossils; they are known today as the largest dinosaurs, being giants with long necks.
- D. Scientists studying fossils of the giant, long-necked dinosaurs called sauropods have been baffled by the largest dinosaurs known today for decades.
Correct Answer & Rationale
Correct Answer: A
Option A effectively combines the two sentences, maintaining clarity and coherence. It clearly identifies sauropods as long-necked giants and links them directly to their fossils, which have puzzled scientists, all in a single, fluid statement. Option B, while informative, awkwardly positions the phrase "whose fossils" and slightly disrupts the flow. Option C introduces unnecessary complexity with a semicolon and the phrase "being giants," which can confuse the reader. Option D is overly verbose and convoluted, making it less effective in conveying the main ideas succinctly.

In context, which word or phrase is best to insert at the beginning of sentence 11? Sentence 11: He spent most of his time writing poems in Spanish instead of studying English.
- A. In addition.
- B. For example.
- C. However.
- D. Indeed.
Correct Answer & Rationale
Correct Answer: C
The choice of "However" effectively contrasts the subject's choice to write poems in Spanish with the expectation that he should be studying English. This juxtaposition highlights a shift in focus, emphasizing the divergence from expected behavior. Option A, "In addition," suggests continuity rather than contrast, which does not align with the sentence's intent. Option B, "For example," implies that the sentence will provide an instance, which is not the case here. Option D, "Indeed," reinforces a statement rather than introducing a contrasting idea, making it unsuitable for the context.

In context, which of the following sentences would be best to insert between sentences 11 and 12 (reproduced below)? By those calculations, it would have taken sauropods a century to reach their full size. A different perspective developed when scientists began to more closely examine various features of sauropod bones.
- A. Like all dinosaurs, sauropods hatched from eggs.
- B. This rather implausible conclusion nonetheless persisted for years.
- C. For decades, sauropods were considered emblematic of the phenomenon of extinction.
- D. Sauropod fossils continue to be discovered in regions spread across the globe.
Correct Answer & Rationale
Correct Answer: B
Option B effectively bridges the gap between the two sentences by highlighting the skepticism surrounding the lengthy growth period of sauropods. It acknowledges the implausibility of the previous conclusion, setting the stage for the subsequent discussion about new scientific insights into sauropod bones. Option A is irrelevant, as it provides basic information about sauropod reproduction that does not relate to their growth or the scientific debate at hand. Option C introduces a different topic—extinction—diverting focus from the growth discussion. Option D, while factual, does not connect to the analysis of growth rates and their implications, making it less suitable for the context.

In context, which is the best version of sentence 1 (reproduced below)? Federico Garcia Lorca was 20th-century Spain’s most famous poet and playwright.

- B. Federico GarcÃa Lorca, was 20th-century Spain's most famous poet and playwright.
- C. Federico GarcÃa Lorca was, 20th-century Spain's, most famous poet and playwright.
- D. Federico GarcÃa Lorca was 20th-century Spain's, most famous poet and playwright.
Correct Answer & Rationale
Correct Answer: A
Option A maintains clarity and grammatical correctness without unnecessary punctuation. It presents Federico Garcia Lorca's identity straightforwardly, enhancing readability. Option B incorrectly places a comma after "García Lorca," which disrupts the flow of the sentence. Option C misuses commas, creating awkward pauses that confuse the reader and detract from the sentence's coherence. Option D also misplaces a comma after "Spain's," which incorrectly separates the subject from its complement, leading to a fragmented thought. Thus, option A stands out as the most effective choice.

Which is the best version of the underlined portion of sentence 6 (reproduced below)? More recent discoveries of sauropod fossils in locations around the world have confirmed that these resilient animals, did indeed walk the earth for millions of years.
- A. (as it is now)
- B. that, these resilient animals
- C. that these resilient animals.
- D. that these resilient animals
Correct Answer & Rationale
Correct Answer: D
Option D is the best choice as it eliminates unnecessary punctuation, creating a smooth and grammatically correct sentence. The phrase "that these resilient animals" flows naturally and maintains clarity. Option A retains the comma, which incorrectly separates the subject from the verb, leading to a fragmented structure. Option B includes an unnecessary comma after "that," disrupting the sentence's flow. Option C, while similar to D, incorrectly ends with a period, making it incomplete and affecting the overall coherence of the sentence.
