(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, where would the following sentence best be placed? How long did it take sauropods to grow to full adult size?
- A. After sentence 3
- B. After sentence 8
- C. After sentence 9
- D. After sentence 12
Correct Answer & Rationale
Correct Answer: C
Placing the question "How long did it take sauropods to grow to full adult size?" after sentence 9 is most effective as it follows a discussion about sauropod growth patterns, providing a logical transition into the specifics of their growth duration. Option A, after sentence 3, is too early as it lacks the necessary context about sauropod growth. Option B, after sentence 8, is close but doesn't fully prepare the reader for the specific inquiry about growth duration. Option D, after sentence 12, is too late, as it disrupts the flow by introducing a new question after concluding details about sauropods.

The passage indicates that ancient astronomers were 'baffled' because:
- A. Their observations disproved the poetic tales of early cosmologies
- B. They lacked the mathematical sophistication needed to calculate astronomical distances
- C. Their theories of planetary movements were more complicated than the movements themselves
- D. They could not reliably predict observable celestial phenomena
Correct Answer & Rationale
Correct Answer: D
Ancient astronomers were 'baffled' primarily because they struggled to reliably predict observable celestial phenomena. This unpredictability challenged their understanding and led to confusion in their astronomical models. Option A is incorrect as it implies a conflict with poetic tales, which was not the primary concern of astronomers. Option B misrepresents the issue; while mathematical sophistication was limited, the core problem was not solely about calculations. Option C inaccurately suggests that their theories were overly complex; rather, the issue lay in their inability to accurately forecast celestial events, which is the essence of their bafflement.

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.
- A. [as it is now]
- 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.

In context, the metaphor in the third sentence ('it was... years') chiefly serves to:
- A. Call attention to the age of the United States as a nation
- B. Question the literary value of the writings by Lewis and Clark
- C. Trivialize the accomplishments of the Lewis and Clark expedition
- D. Place the Lewis and Clark expedition into a broad context
Correct Answer & Rationale
Correct Answer: D
The metaphor in the third sentence effectively places the Lewis and Clark expedition within a broader historical and cultural context, emphasizing its significance in relation to the age of the nation and its development. Option A, while related to the age of the United States, does not capture the metaphor's broader implications. Option B misinterprets the metaphor, as it does not question literary value but rather highlights historical importance. Option C inaccurately suggests that the metaphor diminishes the expedition’s achievements, whereas it actually elevates their significance by situating them within a larger narrative.

Which choice best replaces the underlined portion in sentence 6 (reproduced below) to suggest that, for a time, people were completely caught up with news of the Leonid meteor shower? In the center of the quilt, the 'falling of the stars' illustrates the hours-long Leonid meteor shower that interested people on November 13, 1833.
- A. affected
- B. enthralled
- C. involved
- D. worried
Correct Answer & Rationale
Correct Answer: B
The term "enthralled" effectively conveys a sense of deep fascination and engagement, suggesting that people were completely captivated by the Leonid meteor shower. Option A, "affected," lacks the intensity and emotional connection implied in the context; it merely indicates a change rather than a strong interest. Option C, "involved," suggests participation but does not capture the sense of wonder that the meteor shower inspired. Option D, "worried," introduces an inappropriate negative connotation, as the context is one of excitement and awe, not concern.
