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 author’s primary purpose in writing the essay?

• A. To persuade the reader to have an ECG
• B. To entertain the reader with a heartwarming story
• C. To inform the reader how an electrocardiograph reads the electric currents emitted by the heart
• D. To analyze the difference between the SA node and the AV node

Correct answer: C

Rationale: The author's primary purpose in writing the essay is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. Choice A is incorrect because there is no attempt to persuade the reader to have an ECG. Choice B is incorrect because the essay is focused on providing information rather than entertaining with a heartwarming story. Choice D is incorrect as the essay does not primarily analyze the difference between the SA node and the AV node; instead, it focuses on explaining how an electrocardiograph reads electric currents from the heart.

4. What is the meaning of the word leached as used in the last paragraph?

• A. Sucked
• B. Compressed
• C. Seeped
• D. Materialized

Correct answer: C

5. What is the meaning of the phrase 'phased in' as it is used in the third paragraph?

• A. stunned into silence
• B. confused
• C. implemented in stages
• D. legalized

Correct answer: C

Rationale: 'Phased in' means implemented in stages, referring to the gradual implementation of good manufacturing practices. In the provided extract, it mentions that requirements for good manufacturing practices (GMPs) were phased in for small manufacturers through 2010, indicating a gradual implementation process. The other choices, 'stunned into silence,' 'confused,' and 'legalized,' do not accurately reflect the meaning of 'phased in' in the context of the paragraph.
