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. Which of the following is not mentioned as being important for seniors?

• A. Vitamin B12
• B. Calcium
• C. Nitrates
• D. Exercise

Correct answer: C

Rationale: The passage lists important nutrients for seniors, including fiber, calcium, vitamin D, and B12, while exercise is also discussed as crucial for health. However, nitrates are not mentioned at all, making option C correct since it stands out as the only nutrient not discussed in the context of seniors’ health

3. A vegetarian diet is said to lower all of the following EXCEPT ___________.

• A. The need for protein
• B. The percentage of body fat
• C. The risk of heart disease
• D. Cholesterol

Correct answer: A

Rationale: The passage suggests that a vegetarian diet can provide sufficient protein and lower body fat, heart disease risk, and cholesterol, but it does not suggest that it lowers the need for protein.

4. What is the main idea of the passage about The Sleep Workout?

• A. Insufficient sleep can lead to obesity.
• B. Insufficient sleep inhibits the natural release of human growth hormone in the human body.
• C. Getting the proper amount of uninterrupted sleep plays a major role in the development of muscle.
• D. Developing muscle growth is an effective way to stay healthy as we get older.

Correct answer: C

Rationale: The main idea of the passage is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The passage emphasizes how muscle growth occurs during rest periods following a workout, with sleep being a critical time for muscle fiber rebuilding. The connection between sleep, human growth hormone (HGH) release, and muscle development is highlighted. Choice A is incorrect because while the passage mentions the link between inadequate sleep and obesity due to altered appetite hormones, the main focus is on muscle development. Choice B is incorrect because although the passage discusses HGH release during deep sleep, the primary emphasis is on the role of uninterrupted sleep in muscle development. Choice D is incorrect because while the passage acknowledges that developing muscle growth is essential for health as we age, the key point is the significance of uninterrupted sleep in the muscle development process.

5. What is the meaning of the word 'emitting' as it is used in the second paragraph?

• A. Repelling
• B. Releasing
• C. Closing
• D. Charging

Correct answer: B

Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.
