1. What is the meaning of the word 'sterile' as it is used in the second paragraph?

• A. free of bacteria
• B. healthy
• C. delicious
• D. impotent

Correct answer: A

Rationale: In the context provided, 'sterile' means free of bacteria. The text mentions that raw foods are not sterile and can be a common source of foodborne illnesses due to contamination with harmful bacteria. 'Healthy' (choice B) is incorrect as the term 'sterile' specifically refers to the absence of bacteria, not overall health. 'Delicious' (choice C) is irrelevant to the context of bacteria contamination. 'Impotent' (choice D) is also incorrect as it does not relate to the concept of being free from bacteria.

2. Why did the author write the passage on Getting a Good Night's Sleep?

• A. To explain insomnia and propose solutions for it.
• B. To entertain readers with sleep trivia.
• C. To persuade people to sleep more.
• D. To inform about the benefits of herbs for sleep.

Correct answer: A

Rationale: The correct answer is A. The author wrote the passage to address the issue of insomnia, offering solutions such as sleep hygiene and non-pharmacological therapies. The passage discusses the challenges of insomnia, its impact on daily life, and emphasizes the importance of seeking help to achieve a good night's sleep. Choice B is incorrect as the passage focuses on a serious topic rather than entertaining with trivia. Choice C is incorrect as the passage does not aim to persuade people to sleep more but to address insomnia specifically. Choice D is incorrect as the passage mentions herbs and spices as part of non-pharmacological therapies for insomnia, not primarily focusing on their benefits.

3. 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.

4. The information presented is:

• A. Slanted in favor of newscasters
• B. Slanted against people with deep voices
• C. Balanced in its approach
• D. Not applicable

Correct answer: C

Rationale: The information is balanced in its approach. While the extract mentions that women tend to have shriller voices, making them less desirable public speakers, newscasters, or political candidates, it does not show bias in favor of newscasters or against people with deep voices. The main focus is on the impact of voice qualities such as harshness, rather than promoting or criticizing any specific group.

5. In context, the word 'defective' in the first sentence of the passage means which of the following?

• A. Unusual
• B. Remarkable
• C. Postponed
• D. Faulty

Correct answer: D

Rationale: In the context provided, 'defective' means faulty, referring to the gene that causes cystic fibrosis (CF). The passage explains that CF is caused by a defective gene, resulting in the production of abnormally thick and sticky fluid. The word 'defective' suggests that the gene is not functioning correctly, leading to the symptoms associated with the disease. Therefore, 'faulty' is the correct choice. The other options, 'unusual,' 'remarkable,' and 'postponed,' do not accurately capture the meaning of 'defective' in this context and are therefore incorrect.
