1. What is the meaning of the word leached as used in the last paragraph?

• A. Sucked
• B. Compressed
• C. Seeped
• D. Materialized

Correct answer: C

Rationale: "Leached" refers to the process by which substances, such as lead, seep or dissolve out of materials, in this case, water pipes.

2. What statement about jetlag can be inferred from the passage on Daylight Savings Time?

• A. Jetlag is caused by flying at high speeds.
• B. Jetlag is caused by moving between time zones.
• C. Jetlag is unrelated to time zone changes.
• D. Jetlag is a myth.

Correct answer: B

Rationale: The correct answer is B: 'Jetlag is caused by moving between time zones.' The passage explains that jetlag occurs when moving suddenly from one time zone to another, such as when flying from Asia to North America. This disrupts the body's internal clock, leading to symptoms like tiredness and sleep disturbances. Choice A is incorrect as jetlag is not attributed to high-speed travel but to time zone changes. Choice C is incorrect as the passage clearly links jetlag to changes in time zones. Choice D is incorrect as jetlag is a real phenomenon experienced by individuals who travel across different time zones.

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. 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.

5. What is the meaning of the phrase 'phased in' as it is used in the third paragraph?

• A. stunned into silence
• B. confused
• C. implemented in stages
• D. legalized

Correct answer: C

Rationale: 'Phased in' means implemented in stages, referring to the gradual implementation of good manufacturing practices. In the provided extract, it mentions that requirements for good manufacturing practices (GMPs) were phased in for small manufacturers through 2010, indicating a gradual implementation process. The other choices, 'stunned into silence,' 'confused,' and 'legalized,' do not accurately reflect the meaning of 'phased in' in the context of the paragraph.
