1. Which claim from the passage best describes the benefits of nanotechnology?

Correct answer: D

Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.

2. The author suggests that persistent passivity and imperturbability may be a direct result of which of the following?

Correct answer: B

Rationale: The correct answer is B. The passage highlights that damage to the limbic system, specifically the amygdala, can lead to passivity and lack of aggression. This is supported by the statement that patients with trauma or damage to the amygdala exhibit a complete absence of aggression. Thus, a stroke causing severe tissue damage in the limbic system, including the amygdala, can result in persistent passivity and imperturbability. Choices A, C, and D are incorrect because they do not directly relate to damage in the limbic system, which is specifically mentioned in the passage as the cause of the described behaviors.

3. Choose the best summary of the passage.

Correct answer: A

Rationale: The best summary of the passage emphasizes the importance of certain fats, particularly unsaturated fats, for bodily function. It highlights that after years of negative publicity, experts now recognize the significance of consuming fats for overall health. The passage discusses how fat is essential for cell health, vitamin absorption, and various bodily functions. It also distinguishes between healthier unsaturated fats like olive oil and detrimental trans fats. Choice B is not the best summary as it focuses more on the choice between unsaturated and saturated fats rather than the overall importance of fats. Choice C is incorrect as the passage doesn't solely attribute functioning metabolisms to fat calories. Choice D is not the best summary as it only briefly mentions saturated fats and fried foods, missing the broader context provided in the passage.

4. Which is not mentioned as a possible result of being spanked in childhood?

Correct answer: D

Rationale: The correct answer is D: 'Incontinence.' The passage discusses the negative consequences of spanking in childhood, such as increased aggression, delinquent behavior, and future sexual problems like coercive sex. However, incontinence is not mentioned as a possible result of being spanked. Therefore, it is the correct choice. Choices A, B, and C are all supported by the passage, making them incorrect answers.

5. What is the meaning of the word composed in the first paragraph?

Correct answer: A

Rationale: The word 'composed' means to be made up of or to consist of something. In the provided extract, it describes how a single drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is 'To consist of.' Choice B, 'To break apart,' is incorrect as it is the opposite of 'composed.' Choice C, 'To mix with other elements,' is incorrect as 'composed' refers to being made up of specific components, not mixed with others. Choice D, 'To heat up,' is unrelated to the meaning of 'composed' in this context.
