1. Which of the following is not listed as a detail in the passage about Concussions?

A. Football and lacrosse players suffer the most concussions.
B. More than a million Americans a year suffer concussions.
C. Concussions may result in diminished alertness.
D. It may take longer to recover from a second concussion.

Correct answer: A

Rationale: Skim the passage to identify the detail that does not appear. The sports in choice A are never mentioned, so you do not even need to look at the other choices.

2. What is the author’s attitude toward the use of cosmetics?

A. Sympathetic
B. Mocking
C. Tolerant
D. Disapproving

Correct answer: D

Rationale: The author’s tone is disapproving, as evidenced by the focus on the negative consequences of using cosmetics with harmful ingredients. The passage discusses historical and contemporary health issues related to beauty practices, indicating a critical stance on the use of cosmetics that compromise health, which supports option D.

3. What is the meaning of the word tolerance as used in the last paragraph about Yoga?

A. Open-mindedness.
B. Approval.
C. Endurance.
D. Generosity.

Correct answer: C

Rationale: In this context, "tolerance" refers to the capacity to endure discomfort, particularly in relation to pain during yoga practices. The passage discusses how yoga improves pain tolerance, emphasizing the ability to withstand discomfort rather than any other meanings associated with the term, such as open-mindedness or approval.

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

A. Unusual
B. Remarkable
C. Postponed
D. Faulty

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.

5. What are the three steps of the 'wave of excitation'?

A. The discharge from the SA node, the peak ECG, and the excitement of the ventricle.
B. The excitement of the ventricle, the relaxing of the ventricle, and the systemic neural response.
C. The contraction of the atrium, the relaxation of the atrium, and the contraction of the ventricle.
D. The excitation of the atrium, the excitement of the ventricle, and the relaxing of the ventricle.

Correct answer: D

Rationale: The correct steps of the 'wave of excitation' are the excitation of the atrium, excitement of the ventricle, and relaxation of the ventricle. In the described process, the 'wave of excitation' starts with the discharge from the SA node, leading to the excitation of the atrium. Next, the peak ECG corresponds to the excitement of the ventricle, not its relaxation. Finally, the wave concludes with the relaxation of the ventricle, not its contraction. Therefore, choices A, B, and C are incorrect as they do not accurately describe the sequential steps of the 'wave of excitation' as presented in the extract.
