1. 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.

2. Which sound waves have a lower pitch?

• A. Those waves that are closer together
• B. Those waves that are farther apart
• C. Those waves that travel a long distance
• D. Those waves that travel a short distance

Correct answer: B

Rationale: Sound waves that are farther apart have a lower pitch. The Doppler Effect explains that as objects emitting sound move away, the sound waves become more spaced out, resulting in a lower frequency and a lower pitch. Choice A is incorrect because waves that are closer together have a higher frequency and a higher pitch. Choices C and D are not directly related to determining the pitch of sound waves.

3. What is the meaning of the word 'enlist' as it is used in the second paragraph?

• A. call into service
• B. write down
• C. send away
• D. put across

Correct answer: A

Rationale: In the context of the immune system, 'enlist' means to call into service. Immune cells recruit other cells to fight infection by producing chemicals that regulate their growth, behavior, and direct new recruits to trouble spots. This process is essential for the immune system's defense mechanism. The other choices are incorrect: 'write down' and 'put across' do not capture the action of mobilizing immune cells, and 'send away' is opposite in meaning to what is happening in the immune response.

4. The passage lists all of these benefits of omega-3s EXCEPT ___________.

• A. Reduced blood pressure
• B. Less risk of diabetes
• C. Improved memory
• D. Alleviated depression

Correct answer: B

Rationale: The passage mentions reduced blood pressure, improved memory, and alleviated depression as potential benefits of omega-3s but does not mention a reduced risk of diabetes.

5. What is the meaning of the word 'popular' as it is used in the third paragraph?

• A. complicated
• B. old-fashioned
• C. beloved
• D. for the general public

Correct answer: D

Rationale: In the context provided, 'popular' refers to magazines intended for the general public. The paragraph mentions that Infotrac indexes hundreds of popular magazines and newspapers, including medical journals such as the Journal of the American Medical Association and New England Journal of Medicine. These magazines target a wide audience, making choice D ('for the general public') the correct answer. Choices A, B, and C are incorrect as they do not align with the context of the paragraph.
