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 meaning of the word leached as used in the last paragraph?

A. Sucked
B. Compressed
C. Seeped
D. Materialized

Correct answer: C

Rationale: "Leached" refers to the process by which substances, such as lead, seep or dissolve out of materials, in this case, water pipes.

3. Why did Strauss set up a net during the construction of the Golden Gate Bridge?

A. For suspension
B. For balance
C. For aesthetics
D. For safety

Correct answer: D

Rationale: Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.

4. What is the main idea of the passage about microbes?

A. Recent discoveries are revealing the critical role of microorganisms in maintaining a properly functioning immune system.
B. The human body is host to a staggering number of microorganisms.
C. Bacteriotherapy reintroduces healthy bacteria into a colon lacking the capability to defend against pathogenic agents.
D. Early research has shown remarkable discoveries in the possibilities of bacteriotherapy.

Correct answer: A

Rationale: The main idea of the passage is that recent discoveries are shedding light on the pivotal role of microorganisms in maintaining a properly functioning immune system. The passage discusses how the human body hosts a wide array of microorganisms, emphasizes the importance of these bacteria in the development of the immune system, and explores the potential applications of bacteriotherapy. Choice A is the correct answer because it accurately reflects the central theme discussed in the passage. Choices B, C, and D are incorrect because they focus on specific details or applications mentioned in the passage, rather than capturing the overarching theme of the critical role of microorganisms in immune system function.

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.
