1. What was the author's primary purpose for writing this essay?
- A. To inform the reader about the stages of the water cycle
- B. To explain how rain is formed
- C. To persuade readers to preserve water
- D. To inform the reader about water's importance in life
Correct answer: A
Rationale: The author's primary purpose for writing this essay is to inform the readers about the stages of the water cycle. The essay explains how water moves through the cycle, including processes like precipitation, runoff, evaporation, and condensation. Choice A is correct because the focus is on educating readers about the water cycle, not just explaining how rain is formed (Choice B), persuading readers to preserve water (Choice C), or discussing water's importance in life (Choice D). The detailed explanation of the water cycle provided in the extract supports the correct answer.
2. 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. Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?
- A. HFCS and sugar share a biological structure.
- B. HFCS is cheaper to use than sugar.
- C. HFCS is now used to sweeten a variety of products.
- D. HFCS contains more calories than aspartame.
Correct answer: D
Rationale: The correct answer is D because the passage does not mention that HFCS contains more calories than aspartame. While the passage discusses the concerns and implications of high fructose corn syrup (HFCS), it does not compare its caloric content to aspartame. Detail A is supported by the passage as both HFCS and sugar share a biological structure. Detail B is also mentioned in the passage, stating that HFCS is cheaper to use than sugar. Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.

- A. Walnuts contain omega-3 fatty acids.
- B. Lentils are high in both protein and fiber.

Rationale: The statement about pomegranates being delicious and healthful reflects a subjective opinion about taste and health benefits. This contrasts with the other options, which present factual information about the nutritional content of walnuts, lentils, and oats, making C the correct choice for an opinion.
