(1) Sauropods, known today as the largest dinosaurs, were long-necked giants.(2) Their fossils have baffled scientists for decades.(3) These animals were so large that scientists did not know how they were able to support their own weight—unless they lived entirely in the water.(4) Scientists also argued that these overgrown creatures were not well suited for survival and likely became extinct after only a few generations.(5 ) However, the fossil evidence suggested that sauropods had existed, on land, for quite a long time.(6) 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.(7) As a result, scientists have had to rethink many of their previous assumptions about these creatures.(8) By studying these fossils, they are starting to gain a better understanding of how sauropods lived and adapted to the changing environment around them.(9) One area of particular interest involves the growth rates of the creatures.( 10) Because sauropods are reptiles, most early dinosaur researchers estimated sauropod growth rates based on the growth rates of modern reptiles.(11)By those calculations, it would have taken sauropods a century to reach their full size.(12)A different perspective developed when scientists began to more closely examine various features of sauropod bones.(13)It was determined that the animals' growth rates would actually have been faster than those of modern reptiles and closer to those of large-bodied mammals.
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.

Which is the best way to revise and combine sentences 3 and 4 (reproduced below)? Lorca was the oldest son of a wealthy landowner. He studied literature and law at the University of Granada before turning to writing full-time.
- A. Lorca was the oldest son of a wealthy landowner, studied literature and law at the University of Granada before turning to writing full-time.
- B. The oldest son of a wealthy landowner, Lorca studied literature and law at the University of Granada before turning to writing full-time.
- C. Lorca, the oldest son of a wealthy landowner, studying literature and law at the University of Granada before turning to writing full-time.
- D. The oldest son of a wealthy landowner who studied literature and law at the University of Granada, Lorca then turning to writing full-time.
Correct Answer & Rationale
Correct Answer: B
Option B effectively combines the two sentences by placing the subject, Lorca, at the beginning and clearly linking his identity to his actions. This structure maintains clarity and coherence, allowing readers to easily follow the progression of ideas. Option A lacks a conjunction, resulting in a sentence fragment that does not convey a complete thought. Option C incorrectly uses "studying," which creates a grammatical error by failing to connect the clauses properly. Option D introduces unnecessary complexity with "who studied," and the phrase "Lorca then turning" is awkward and grammatically incorrect. Thus, option B stands out as the most coherent and grammatically sound choice.

The writer is considering adding the following sentence to the end of the fourth paragraph: 'Surprisingly, according to The Economist, there were 1.6 million commercial farms in Brazil in 2010.' Should the writer make this addition here?
- A. Yes, because it emphasizes the paragraph's focus on the economic power of large farms.
- B. Yes, because it uses concrete data to provide context about local farms and commercial farms.
- C. No, because it is unrelated to the economic challenges small farms may face.
- D. No, because it fails to show a clear connection to the paragraph's focus on supporting local farms.
Correct Answer & Rationale
Correct Answer: B
Adding the sentence enhances the paragraph by providing concrete data, which helps contextualize the discussion about local and commercial farms. It bridges the gap between the economic landscape and the realities faced by different types of farms, enriching the reader's understanding. Option A misinterprets the focus; while large farms are mentioned, the emphasis is on the economic challenges faced by smaller farms. Option C incorrectly suggests that the data is unrelated; understanding the number of commercial farms is essential to discussing the economic landscape. Option D overlooks that the data can indeed support a broader discussion about local farms by contrasting them with commercial operations.

Which is the best version of the underlined portion of sentence 5 (reproduced below)? However, the fossil evidence suggested that sauropods will have existed, on land, for quite a long time.
- A. (as it is now)
- B. exist,
- C. existed,
- D. will exist.
Correct Answer & Rationale
Correct Answer: C
The choice "existed" accurately reflects the past tense required by the context, indicating that the fossil evidence pertains to a time when sauropods were already present on Earth. Option A, retaining the original phrasing, incorrectly uses "will have existed," which suggests a future perfect tense that does not align with the historical nature of fossil evidence. Option B, "exist," shifts to present tense, failing to convey the past timeframe relevant to the fossils. Option D, "will exist," also implies a future occurrence, which is inconsistent with the established fact that sauropods are known to have lived in the past.
