1. 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.

- A. The CDC keeps an eye out for new potentially threatening health issues
- B. Children require several more hours of sleep per night than adults do
- C. More people are staying up at night to surf the Internet or watch television
- D. Lack of adequate sleep is becoming a major national health problem
Correct answer: D
Rationale: The main idea of the passage is that lack of adequate sleep is becoming a major national health problem.
3. What is the overall tone of the essay about A Short History of the CDC?
- A. Appreciative.
- B. Awestruck.
- C. Somber.
- D. Disheartened.
Correct answer: A
Rationale: The tone of the essay is appreciative, reflecting a recognition of the CDC's historical contributions to public health. The passage highlights the organization's evolution and its significant impact on disease control and prevention, suggesting a positive and respectful view of its work over the years, making A the correct choice.
4. Which statement is not listed as a detail within the passage?
- A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
- B. The signal has a characteristic record called the electrocardiogram.
- C. The 'wave of excitation' starts at the SA node.
- D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.
Correct answer: A
Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.
5. What is stated in this paragraph?
- A. Some men have harsh voices
- B. Relaxed people often have harsh voices
- C. Not everyone finds a harsh voice irritating
- D. Harsh voice qualities usually come from too much tension in the throat and jaw
Correct answer: D
Rationale: The correct answer is D. The paragraph explains that harsh voice qualities usually result from too much tension in the throat and jaw. It further discusses how tension tightens muscles, leading to unpleasant voice tones. While the paragraph addresses the issue of harsh voices, it does not mention that only some men have harsh voices (choice A) or that relaxed people often exhibit this quality (choice B). Additionally, the paragraph does not touch upon whether everyone finds harsh voices irritating (choice C), only stating that not everyone may be bothered by it.
