1. 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.

2. What is the meaning of the word 'phenomenon' in the second paragraph?

• A. Something that is lifeless to the senses
• B. Something that is nonchalant
• C. Something that is significant but unusual
• D. Something that is chemical in origin

Correct answer: C

Rationale: In the context of the second paragraph, 'phenomenon' refers to something significant and unusual, specifically describing the scientific phenomenon known as the Doppler Effect. This effect explains the change in frequency of sound waves when a source of sound and the observer are in relative motion. Choices A, B, and D are incorrect because they do not accurately reflect the meaning of 'phenomenon' in this context. 'Lifeless to the senses,' 'nonchalant,' and 'chemical in origin' do not align with the description of the Doppler Effect, which is a notable and uncommon scientific occurrence.

3. What is the author’s primary purpose in writing this essay?

• A. To persuade
• B. To entertain
• C. To analyze
• D. To reflect

Correct answer: A

Rationale: The author’s enthusiastic and supportive tone toward yoga—stating that it is an exercise that "everyone should try"—indicates a clear intent to persuade the audience about the benefits of yoga. This aligns with choice A, as the primary purpose of the essay is to promote yoga as a valuable practice

4. Why does the author mention 'impact craters' in line 16?

• A. To explain the corrosive effects of atmospheric weathering
• B. To explain why the Moon has no plant life because of meteorites
• C. To show the result of the Moon not having an atmosphere
• D. To show the result of the Moon not having active tectonic or volcanic activity

Correct answer: C

Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.

5. What is the author’s primary purpose in writing the essay about High Fructose Corn Syrup?

• A. To inform.
• B. To persuade.
• C. To entertain.
• D. To analyze.

Correct answer: A

Rationale: The correct answer is A: 'To inform.' The essay provides detailed information about High Fructose Corn Syrup (HFCS), discussing its impact on health, how it is derived, its link to health issues like obesity, and the ongoing debates surrounding its consumption and health implications. The primary goal of the author is to educate the readers about HFCS and its effects, rather than persuade them to take a particular stance (choice B), entertain them (choice C), or analyze the topic in depth (choice D). The essay presents facts, studies, and expert opinions to inform the audience about the controversies and health risks associated with HFCS consumption, aiming to enhance the readers' knowledge and understanding of this sweetener's implications on health.
