1. 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.

2. Which of the following would be the best title for this passage?

• A. Bicycles are better.
• B. A ride through the history of bicycles.
• C. Cycle your way to fitness.
• D. The popularity of bicycles.

Correct answer: B

Rationale: The best title for this passage would be 'A ride through the history of bicycles' as it provides a comprehensive overview of the historical development of bicycles from their invention to modern times. Choice A, 'Bicycles are better,' is incorrect as it does not capture the essence of the passage, which focuses on the history and evolution of bicycles rather than their superiority. Choice C, 'Cycle your way to fitness,' is misleading as the passage does not primarily discuss the fitness aspect of cycling but instead focuses on the evolution of bicycle design. Choice D, 'The popularity of bicycles,' is too narrow as it only touches on one aspect mentioned briefly in the passage, while the passage covers a broader historical perspective.

3. Which of the following is not listed as a detail in the passage about microbes?

• A. Babies are born coated with germs from the birth canal.
• B. Mice and humans respond to microbes differently.
• C. Few people share the same microbes in the same quantities.
• D. Human bodies contain far more microbes than they do cells.

Correct answer: B

Rationale: The correct answer is B because the passage does not detail that mice and humans respond to microbes differently. The passage discusses how laboratory mice required a particular strain of bacteria to help their immune systems function correctly, indicating a difference in how mice and humans respond to microbes. Choices A, C, and D are all details mentioned in the passage: A discusses babies being coated with germs from the birth canal, C talks about the variation in microbes among individuals, and D states that human bodies contain more microbes than cells.

4. What is the meaning of the word "pulses" as it appears in the first paragraph?

• A. The regular throbbing of the arteries caused by successive contractions of the heart
• B. The general attitude of the public or a specific population toward health concerns
• C. The edible seeds produced by legumes such as peas, beans, or lentils
• D. Any type of food with animal origins such as butter, honey, or eggs

Correct answer: C

Rationale: In the context of the passage, "pulses" refers to the edible seeds produced by legumes.

5. The word 'track' as used in the last paragraph of the passage can best be defined as ___________.

• A. Keep a record of
• B. A new attitude
• C. Follow carefully
• D. A paved, circular path

Correct answer: D

Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.
