From the earliest times, the complications inherent in deciphering the movements of planets in the night sky must have seemed a curse to baffled astronomers. In the long run, though, they proved a blessing to the development of cosmology, the study of the physical universe. Had the celestial motions been simple, it might have been possible to explain them solely in terms of the simple, poetic tales that had characterized the early cosmologies. Instead, these motions proved to be so intricate and subtle that astronomers could not predict them accurately without eventually coming to terms with the physical reality of how and where the Sun, Moon, and planets actually move in real, three-dimensional space.
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.

Which choice best replaces the underlined portion of sentence 1 (reproduced below)? When selecting her ingredients, a chef has a seemingly small-but nonetheless consequential choice-she can patronize a conventional grocery store, or she can turn to a nearby farm.
- A. small but nonetheless consequential choice,
- B. small but nonetheless consequential choice:
- C. small-but nonetheless consequential choice;
- D. small but nonetheless, consequential choice,
Correct Answer & Rationale
Correct Answer: B
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.

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.

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.

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.
