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. 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.

3. The information presented in this article is?

• A. Against eating and drinking
• B. Against drinking alcohol
• C. Against eating rich foods
• D. Unbiased and informative.

Correct answer: D

Rationale: The information presented in the article is unbiased in its approach. While the article highlights the potential issues related to overeating and alcohol abuse, it does not explicitly advocate against eating and drinking, drinking alcohol, or eating rich foods. The primary focus is on the negative consequences of overeating and alcohol abuse, making choice D, 'Unbiased and informative,' the correct answer. Choices A, B, and C are incorrect as they are not supported by the content of the article; it merely discusses the risks associated with overeating and alcohol abuse without taking a stand against them.

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. Which statement from the selection presents a fact rather than an opinion?

• A. One of the worst voice qualities is harshness
• B. Harsh voice qualities usually come from too much tension in the throat and jaw
• C. Your voice will sound unpleasant if it is shrill, grating, hard, piercing, brassy, too loud, or too nasal
• D. Because tension occurs in higher pitched voices, women tend to have shriller voices than men, which usually makes them less desirable public speakers, newscasters, or political candidates

Correct answer: B

Rationale: Statement B, 'Harsh voice qualities usually come from too much tension in the throat and jaw,' presents a fact rather than an opinion. This statement provides a clear and objective observation about the potential cause of harsh voice qualities, based on physical tension in specific areas of the body, which can be objectively measured and identified. Choice A is an opinion as it states 'One of the worst voice qualities is harshness' without providing a verifiable basis. Choice C lists subjective descriptors of an unpleasant voice without stating a definite cause. Choice D introduces a gender-based assertion about voice quality, making it an opinion rather than a factual observation.
