What was the author’s primary purpose for writing this essay?

• A. To persuade the reader to conserve water
• B. To persuade the reader that runoff is not the best way to collect water
• C. To analyze different types of runoff
• D. To inform the reader about the stages of the water cycle

Correct Answer: D
Rationale: The correct answer is D. The author's primary purpose for writing the essay is to inform the reader about the stages of the water cycle. The essay discusses the various stages of the water cycle, including precipitation, runoff, evaporation, and condensation. Choices A, B, and C are incorrect because the essay focuses on explaining the water cycle stages rather than persuading the reader to conserve water, discussing the effectiveness of runoff, or analyzing different types of runoff.

Which statement would not be inferred by the reader in the passage about MRSA?

• A. Hospitals may soon limit the spread of infection with a new textile.
• B. MRSA begins by infecting the skin.
• C. You are most likely to contract MRSA in a crowded location.
• D. Used clothing stores may harbor MRSA.

Correct Answer: D
Rationale: The correct answer is D: 'Used clothing stores may harbor MRSA.' This statement is not supported by the passage. The passage mentions the spread of MRSA in hospitals, gyms, locker rooms, swimming pools, and other settings with frequent human contact, but it does not mention used clothing stores as a common location for MRSA. Therefore, it is an unlikely inference. Choice A is supported by the passage as it discusses the development of a new textile to halt the spread of hospital-associated MRSA. Choice B is also supported as the passage mentions MRSA as a skin infection. Choice C is supported by the passage as it states that MRSA has become ubiquitous in settings with frequent human contact.

Which statement could be inferred from the passage?

• A. The Georgia lab had conducted a previous study on the connection between exercise and energy.
• B. Exercise regimes are not recommended for patients with serious health problems.
• C. An increase in energy levels does not always correspond directly to a reduction in fatigue.
• D. There were fewer than 10 participants in each group in the Georgia study.

Correct Answer: A
Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before. Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions. Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue. Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.

Why was the roadway of the Golden Gate Bridge so dangerous to build?

• A. It was located above a fast-moving river.
• B. It had to be perfectly balanced to avoid collapse.
• C. The materials used were very unstable.
• D. It was built during bad weather.

Correct Answer: B
Rationale: The correct answer is B. The passage describes how the road had to be balanced during construction to avoid collapse into the bay. Choice A is incorrect as the Golden Gate Bridge crosses a strait, not a river. Choice C is incorrect as there is no mention of unstable materials. Choice D is incorrect as bad weather is not highlighted as a specific reason for the danger in building the roadway.
