1. In context, the word 'defective' in the first sentence of the passage means which of the following?

Correct answer: D

Rationale: In the context provided, 'defective' means faulty, referring to the gene that causes cystic fibrosis (CF). The passage explains that CF is caused by a defective gene, resulting in the production of abnormally thick and sticky fluid. The word 'defective' suggests that the gene is not functioning correctly, leading to the symptoms associated with the disease. Therefore, 'faulty' is the correct choice. The other options, 'unusual,' 'remarkable,' and 'postponed,' do not accurately capture the meaning of 'defective' in this context and are therefore incorrect.

2. What is the meaning of the word serendipity as it is used in the first paragraph?

Correct answer: A

Rationale: The word "serendipity" refers to a fortunate coincidence or chance, describing how Beto Pérez invented Zumba accidentally.

3. What is the main idea of the passage about High Fructose Corn Syrup?

Correct answer: B

Rationale: The main idea of the passage about High Fructose Corn Syrup is that it may be contributing to obesity in America. This is evident from the information provided in the extract, which discusses how HFCS has been linked to health issues, including obesity. Choice A is incorrect because the passage primarily focuses on the potential health risks associated with HFCS consumption, not just the examination by the American Medical Association. Choice C is irrelevant as it only talks about the manufacturing process of HFCS, which is not the central theme of the passage. Choice D is incorrect as it emphasizes the preference of rats for HFCS, which is a minor point compared to the potential impact on human health, particularly in relation to obesity.

4. What is one of the author’s primary purposes in writing this essay?

Correct answer: A

Rationale: The author primarily aims to persuade the reader of the health benefits of omega-3 fatty acids and encourages ensuring sufficient omega-3 intake through diet.

5. What is the meaning of the word consensus as it is used in the last paragraph about Barefoot Running?

Correct answer: D

Rationale: "Consensus" refers to a general agreement or unanimity among individuals, particularly regarding the safety and effectiveness of barefoot running. The passage discusses differing opinions on this subject, indicating that there is not a unanimous agreement. Thus, choice D accurately captures the meaning of "consensus" within the context of the discussion.
