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 meaning of the word 'shifts' as used in the third paragraph?

A. Alterations
B. Stints
C. Removals
D. Transfers

Correct answer: A

Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.

3. Which detail is not given as a side effect of NSAIDs?

A. Nausea
B. Headache
C. Weight loss
D. Dizziness

Correct answer: C

Rationale: The passage lists several side effects of NSAIDs, including nausea, headache, and dizziness. However, weight loss is not mentioned as a side effect, making option C the correct choice since it does not align with the details provided in the text.

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

A. Runners who take their shoes off may face some hazards.
B. Modern running shoes may increase the odds for injury.
C. Walking barefoot is good for the muscles and tendons.
D. Before 1950, even Olympic runners ran barefoot.

Correct answer: D

Rationale: The passage does not imply that Olympic runners specifically ran barefoot before 1950. While it discusses historical context regarding running shoes, the claim about Olympic runners is not substantiated within the text, making D the correct answer. It represents an inference that cannot be drawn from the provided information.

5. FRAX takes into account all of the following factors EXCEPT ___________.

A. Lifestyle choices
B. Exposure to toxins
C. Genetic heritage
D. Exposure to sunlight

Correct answer: B

Rationale: FRAX, a tool used to assess fracture risk, considers various factors like lifestyle choices, genetic heritage, and exposure to sunlight. However, exposure to toxins is not mentioned in the provided extract as a factor considered by FRAX. Therefore, the correct answer is B. Exposure to toxins is unrelated to fracture risk assessment as per the information provided. Lifestyle choices, genetic heritage, and exposure to sunlight are all factors that FRAX takes into consideration to determine the risk of experiencing a fracture within the next decade.
