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 statements is an opinion related to MRSA?

A. Hand-washing stations are one means of combating MRSA infection.
B. Not all Staphylococcus bacteria are resistant to antibiotics.
C. Hospitals in the United States should quickly adopt the use of new germ-fighting textiles.
D. MRSA infection kills more people in the United States than does HIV/AIDS.

Correct answer: C

Rationale: The correct answer is C because it is an opinion rather than a verifiable fact. The statement suggests a recommendation for hospitals to adopt new germ-fighting textiles swiftly, which is a subjective viewpoint and not objectively measurable. Choices A and B are factual statements regarding combating MRSA infection and antibiotic resistance, respectively. Choice D provides a comparison of MRSA infection with HIV/AIDS, which is a factual statement based on statistical data. Therefore, C is the only choice that presents an opinion rather than a fact.

3. What does the passage about the Water Cycle explain?

A. The water cycle consists of precipitation, evaporation, and condensation.
B. The water cycle is a continuous process of recycling water on Earth.
C. Rain is the most important part of the water cycle.
D. Evaporation is the final step in the water cycle.

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, starting with precipitation (rain, snow, sleet, or hail) falling to the ground, followed by runoff, evaporation transforming liquid water into water vapor, and finally condensation turning water vapor back into liquid. Choice B is incorrect because it is too broad and doesn't specifically address the stages of the water cycle. Choice C is incorrect as rain is just one part of the water cycle and not the most important. Choice D is incorrect as evaporation is not the final step but one of the stages of the water cycle.

4. Which statement would not be inferred by the reader in the passage about Hypertension?

A. Maintaining a healthy weight may help to prevent hypertension.
B. There is presently no reliable treatment for hypertension.
C. Your ethnicity may contribute to your risk for hypertension.
D. A 60-year-old is more likely to have hypertension than a teenager is.

Correct answer: B

Rationale: The correct answer is B. The passage clearly states that there are treatments for hypertension, so the statement that there is presently no reliable treatment for hypertension cannot be inferred from the text. Choice A can be inferred from paragraph 3 where it mentions losing weight to decrease blood pressure. Choice C can be inferred from paragraph 1 where it states that African Americans are more likely to have hypertension. Choice D can be inferred from paragraph 2 where it explains that older people are most often diagnosed with hypertension due to changes in blood vessels as they age.

5. What is the meaning of the word tolerance as used in the last paragraph about Yoga?

A. Open-mindedness.
B. Approval.
C. Endurance.
D. Generosity.

Correct answer: C

Rationale: In this context, "tolerance" refers to the capacity to endure discomfort, particularly in relation to pain during yoga practices. The passage discusses how yoga improves pain tolerance, emphasizing the ability to withstand discomfort rather than any other meanings associated with the term, such as open-mindedness or approval.
