Bones found in South America reveal a bizarre new dinosaur Based on an ancestry that links it to Tyrannosaurus rock, this reptile should have been a meat eater. Instead, it preferred plants. Researchers described the new species in Nature. its genus name – Chilesaurus – reflects that it was found in what's now Chile. The team that discovered the fossils gave it a species name of diegosuarezi to honor Diego Suarez. While just 7 years old, Diego found the first dinosaur bones in the same general area of Chile, It's a place know as to Toqur Fomation C. diegosuarezi roamed South America around 150 million years ago. It measured about 3 meters (roughly 10 feet) from head to tail. Its sturdy back legs, thin body, and short, stout arms made it look a bit like T. rex. But it also had a long neck, small head, and a mouth full of leaf-shaped teeth. These features gave it a more Brontosaurus-like appearance. And like Brontosaurus, it would have eaten plants, making it an herbivore
When the author writes that Chilesaurus diegosuarezi “should have been a meat-eater,†she most likely means that the species:
- A. would have been healthier if it had eaten meat
- B. would have grown even larger if it had eaten meat
- C. had the head, neck, and teeth of a meat-eater
- D. had body features similar to those of its meat-eating relative
Correct Answer & Rationale
Correct Answer: D
The statement implies that Chilesaurus diegosuarezi possesses physical characteristics akin to those of carnivorous dinosaurs. Option D accurately reflects this by highlighting that its body features resemble those of its meat-eating relatives, suggesting an evolutionary expectation based on morphology. Option A incorrectly assumes a health benefit from a meat-based diet, which is not the focus of the author's observation. Option B speculates on size without evidence, as diet does not directly correlate with growth potential in this context. Option C, while partially true about its head and teeth, overlooks the broader comparison to body features, making D the most comprehensive choice.

Why does the author place quotation marks around the word 'patriotic' (sentence 2)?
- A. To attribute to postwar Americans the perception of Wrigley’s gum as patriotic
- B. To praise the patriotism the Wrigley Company demonstrated during wartime
- C. To show that American soldiers used the word 'patriotic' to describe Wrigley’s gum
- D. To reveal that the Wrigley Company changed the name of its gum to include the word 'patriotic'
Correct Answer & Rationale
Correct Answer: A
The use of quotation marks around 'patriotic' indicates that the term reflects the perception held by postwar Americans rather than the author's own endorsement. This suggests a distance from the term, highlighting it as a viewpoint rather than an absolute truth. Option B misinterprets the author's intent; the quotation marks do not imply praise for the Wrigley Company's actions. Option C inaccurately suggests that soldiers specifically coined the term in reference to the gum, which is not supported by the context. Option D incorrectly assumes that the company changed the product name, which is not indicated in the text.

In context, the statement that the woman is 'draped from brow to ankle in gold and wind-crushed linen' (sentence 10) primarily:
- A. reveals the narrator's assumptions about the woman's income
- B. explains why the woman might be uncomfortable in the cold weather
- C. shows how different the woman's clothing is from the narrator's clothing
- D. emphasizes how out of place the woman seems in the surrounding environment
Correct Answer & Rationale
Correct Answer: D
The description of the woman being "draped from brow to ankle in gold and wind-crushed linen" emphasizes her opulent attire, suggesting she is out of place in her surroundings. This stark contrast highlights her distinctiveness compared to the environment, reinforcing her isolation. Option A misinterprets the focus on income rather than the visual impact of her clothing. Option B incorrectly assumes discomfort from the cold, which is not the primary focus of the imagery. Option C, while noting a difference in clothing, fails to capture the broader context of the woman’s disconnection from her environment, which is central to the statement.

The author of Passage 2 would most likely respond to the statement in the fifth sentence of Passage 1 ('Environmentalists must face the fact that unless high-yield crop varieties, pesticides, and fertilizers are widely used in developing nations, the world's food supply will be outstripped by spiraling demand') by arguing that:
- A. industrialized nations pose a greater threat to the environment than do developing nations
- B. many fertilizers are organic substances that produce no ill effects in humans
- C. agricultural chemicals can be used on a small scale and still significantly improve crop yields
- D. the use of pesticides is unnecessary if high-yield crop varieties are adopted
Correct Answer & Rationale
Correct Answer: C
Option C aligns with the idea that improving crop yields can be achieved through targeted use of agricultural chemicals, suggesting a balanced approach rather than widespread reliance. This reflects the author's likely advocacy for sustainable practices that enhance productivity without overwhelming environmental concerns. Option A diverts the focus to industrialized nations, which may not directly address the statement's emphasis on developing nations' agricultural needs. Option B incorrectly implies that all fertilizers are harmless, overlooking potential environmental impacts. Option D dismisses the potential benefits of pesticides entirely, which may not align with the author's nuanced view on agricultural practices.

The author implies that the social sciences:
- A. are valued for their techniques
- B. can make no contribution to progress
- C. cannot deal with long-term issues
- D. may someday add to the world's knowledge
Correct Answer & Rationale
Correct Answer: D
The social sciences are portrayed as fields that hold potential for future contributions to global knowledge, indicating optimism about their evolving role. Option A suggests that their value lies solely in techniques, which limits their broader impact. Option B dismisses their potential entirely, contradicting the author's implication of future contributions. Option C incorrectly asserts that social sciences cannot address long-term issues, overlooking their capability to analyze historical trends and societal changes. Thus, the emphasis on future contributions aligns best with the text's implications.
