(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.

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.

The main idea of the passage is that some types of poison frogs:
- A. have developed the capacity to protect themselves from the poison they carry in their skin
- B. could eventually produce a natural pain relief option for people who suffer from headaches
- C. combine chemicals from their food to create a toxic substance that keeps them safe from predators
- D. can be grouped based on the changes they've made to their nicotinic acetylcholine receptors
Correct Answer & Rationale
Correct Answer: A
Option A highlights the unique adaptation of certain poison frogs, emphasizing their ability to protect themselves from their own toxins. This reflects a key aspect of their survival strategy. Option B, while interesting, suggests a potential human application of frog toxins that is not the main focus of the passage. Option C inaccurately attributes the creation of toxins solely to food sources, overlooking the frogs' inherent toxic traits. Option D focuses on a specific biological mechanism that, while relevant, does not encapsulate the broader theme of self-protection central to the passage.

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.

In the passage, the author refers to the photography technique of double exposure primarily to:
- A. Explain that Rodriguez frequently uses that technique to create eerie and distorted representations of city life
- B. Illustrate how Rodriguez's innovative use of double exposure inspired other photographers to do so as well
- C. Provide an example of how Rodriguez explored the tension between his identity as a photographer and as a scholar
- D. Set up a metaphor comparing that technique to the way Rodriguez's work depicts the duality of Los Angeles
Correct Answer & Rationale
Correct Answer: D
The reference to double exposure serves as a metaphor for the duality of Los Angeles, highlighting the complexity and contrasting elements within the city. This choice effectively encapsulates Rodriguez's artistic vision, illustrating how his work reflects both the vibrant and shadowy aspects of urban life. Option A inaccurately suggests a focus on Rodriguez's frequent use of the technique rather than its metaphorical significance. Option B misinterprets the intent, as the passage emphasizes Rodriguez's personal exploration rather than his influence on others. Option C, while relevant, does not capture the primary purpose of the metaphor, which centers on the depiction of duality rather than identity tension.
