(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.

Option B effectively uses a colon to introduce the two alternatives, enhancing clarity. The colon indicates that what follows elaborates on the choice being discussed. Option A lacks proper punctuation to separate the phrases, making it less clear. Option C incorrectly uses a semicolon, which is inappropriate here as it suggests a stronger separation between clauses than intended. Option D misplaces the comma, creating an unnecessary pause that disrupts the flow of the sentence. Overall, option B best maintains the sentence's coherence while clearly presenting the alternatives.

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 version of the underlined portion of sentence 2 (reproduced below)? Supposing a store may provide benefits such as a broad range of options, a local farm can offer major advantages of its own.
- A. (as it is now)
- B. When a store supposes it
- C. Although a store
- D. A store though
Correct Answer & Rationale
Correct Answer: C
Option C, "Although a store," introduces a contrast between the benefits of a store and those of a local farm, enhancing the sentence's clarity. This structure effectively highlights the unique advantages of local farms, making the comparison more impactful. Option A maintains the original phrasing but lacks the contrast needed for a stronger argument. Option B, "When a store supposes it," introduces ambiguity and weakens the sentence by suggesting uncertainty rather than presenting a comparison. Option D, "A store though," is informal and does not establish a clear relationship between the two subjects, ultimately reducing the sentence's effectiveness.

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.
