(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 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.

Which choice best replaces the underlined portion of sentence 2 (reproduced below)? The pictorial quilts created by a former slave named Harriet Powers, in addition, were remarkable for their bold storytelling techniques and their unique subject matter.
- A. by contrast,
- B. for example,
- C. it so happens,
- D. moreover,
Correct Answer & Rationale
Correct Answer: D
The phrase "in addition" suggests that the following information will build on or add to the previous point. Option D, "moreover," effectively conveys this continuation of thought, emphasizing that Harriet Powers' quilts not only have a historical significance but also possess remarkable qualities. Option A, "by contrast," implies a comparison that highlights differences, which does not fit the context. Option B, "for example," indicates a specific illustration rather than adding information. Option C, "it so happens," is too vague and does not establish a clear connection to the preceding statement. Thus, "moreover" is the most suitable choice for enhancing the sentence's cohesiveness.

To make the third and fourth paragraphs most logical, sentence 12 should be placed:
- A. where it is now
- B. after sentence 8
- C. after sentence 9
- D. after sentence 13
Correct Answer & Rationale
Correct Answer: D
Placing sentence 12 after sentence 13 enhances the flow by effectively connecting the ideas presented in the preceding sentences. This positioning allows for a smooth transition, maintaining coherence in the narrative. Option A retains sentence 12 in its current position, disrupting the logical progression of the paragraphs. Option B, placing it after sentence 8, creates a gap in context, as the ideas would not align well. Option C, following sentence 9, also fails to provide the necessary linkage, leaving the reader confused about the relationship between the concepts. Thus, option D is the most logical choice for clarity and coherence.

Which sentence should be deleted because it contains irrelevant information?
- A. Sentence 6
- B. Sentence 7
- C. Sentence 9
- D. Sentence 14
Correct Answer & Rationale
Correct Answer: C
Sentence 9 introduces information that does not directly support the main argument or theme of the passage, making it irrelevant to the central discussion. In contrast, Sentence 6 provides context, Sentence 7 offers a critical example, and Sentence 14 concludes the argument effectively. Each of these sentences contributes meaningfully to the overall coherence and purpose of the text. Removing Sentence 9 enhances clarity by eliminating distractions, allowing the reader to focus on the essential points being made.

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.
