(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.

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.

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.

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.

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.
