1. 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.
2. What is the author's reason for writing the passage on the White Elephant?
- A. To inform readers about Thailand's historical customs.
- B. To entertain readers with the origins of the term 'white elephant.'
- C. To explain the tradition of giving white elephants.
- D. To criticize the tradition of giving white elephants as gifts.
Correct answer: C
Rationale: The correct answer is C: 'To explain the tradition of giving white elephants.' The passage provides historical context about the practice of giving white elephants as gifts in ancient Siam, now Thailand. It explains how white elephants were considered sacred, could not be put to work, and became a burden to the recipients. The author's purpose is to shed light on this tradition and its implications, not to inform readers about Thailand in general (choice A), entertain with fun facts (choice B), or criticize the tradition (choice D). Choices A and B are incorrect because the passage focuses specifically on the tradition of giving white elephants, not on broader aspects of Thailand or entertainment. Choice D is incorrect because the passage does not criticize the tradition but rather provides a factual account of its historical significance.
3. In this passage, which of the following is not mentioned as a role of HGH in the human body?
- A. Regulating the metabolism.
- B. Stimulating the immune system.
- C. Regulating leptin, an appetite-controlling hormone.
- D. Facilitating calcium retention.
Correct answer: C
Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.
4. What is the best summary of this passage?
- A. The heart regulates oxygen flow and waste disposal, with the kidneys aiding in salt and water absorption.
- B. The cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys.
- C. Baroreceptors send impulses to regulate blood pressure by affecting the heart, arteries, and veins.
- D. Chemoreceptors monitor oxygen levels to impact blood pressure.
Correct answer: B
Rationale: The correct answer is B because it provides a comprehensive summary of the passage, explaining how the cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys. Choice A is incorrect as it only focuses on the heart and kidneys without mentioning the broader cardiovascular system. Choice C is incorrect as it solely emphasizes the role of baroreceptors in regulating blood pressure. Choice D is incorrect as it oversimplifies the role of chemoreceptors in monitoring oxygen levels without mentioning their impact on blood pressure regulation.
5. What is the main idea of the passage about microbes?
- A. Recent discoveries are revealing the critical role of microorganisms in maintaining a properly functioning immune system.
- B. The human body is host to a staggering number of microorganisms.
- C. Bacteriotherapy reintroduces healthy bacteria into a colon lacking the capability to defend against pathogenic agents.
- D. Early research has shown remarkable discoveries in the possibilities of bacteriotherapy.
Correct answer: A
Rationale: The main idea of the passage is that recent discoveries are shedding light on the pivotal role of microorganisms in maintaining a properly functioning immune system. The passage discusses how the human body hosts a wide array of microorganisms, emphasizes the importance of these bacteria in the development of the immune system, and explores the potential applications of bacteriotherapy. Choice A is the correct answer because it accurately reflects the central theme discussed in the passage. Choices B, C, and D are incorrect because they focus on specific details or applications mentioned in the passage, rather than capturing the overarching theme of the critical role of microorganisms in immune system function.
