1. What is the meaning of the word 'booking' as used in the first paragraph?

• A. Scheduling
• B. Contracting
• C. Traveling
• D. Charging

Correct answer: A

Rationale: In this context, 'booking' refers to scheduling appointments for bone density tests. The correct choice is 'A: Scheduling' because in the given text, women are booking bone density tests to ensure their bone health. 'Contracting' (Choice B) is incorrect as it does not fit the context of making appointments. 'Traveling' (Choice C) and 'Charging' (Choice D) are also irrelevant to the context of scheduling appointments for medical tests.

2. 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.

3. 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.

4. What is stated in the passage?

• A. Physical illness can cause insomnia.
• B. Exercise causes insomnia.
• C. There is no solution to insomnia.
• D. Sleep is unnecessary for good health.

Correct answer: A

Rationale: The correct answer is A: 'Physical illness can cause insomnia.' The passage mentions that chronic insomnia can result from a medical illness, among other conditions. This indicates a direct link between physical illness and insomnia. Choice B is incorrect as the passage does not mention exercise causing insomnia but actually suggests developing good sleep habits as a solution. Choice C is incorrect as the passage provides solutions to insomnia, such as sleep hygiene and non-pharmacological therapies. Choice D is incorrect as the passage emphasizes the importance of getting a good night's sleep for good health, implying that sleep is necessary.

5. What is the best summary of the passage?

• A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
• B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
• C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
• D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.
