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

• A. Scientists can develop novel technologies and products.
• B. Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers.
• C. The different colors can be used in simple medical tests to indicate infection or disease.
• D. Unique properties of materials emerge.

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. What is the best definition of 'efficient' as used in the third paragraph?

• A. Slow but steady.
• B. Productive without waste.
• C. Wasteful and careless.
• D. Quick but sloppy.

Correct answer: B

Rationale: The correct definition of 'efficient' in the third paragraph is 'Productive without waste.' In the extract provided, it discusses how different cultures developed tools like cutlery and chopsticks to efficiently eat food. Efficiency here refers to getting something done with the least amount of waste. Choices A, C, and D are incorrect because they do not accurately capture the concept of efficiency discussed in the passage.

Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.
