1. What is the main idea of the passage about The Sleep Workout?

A. Insufficient sleep can lead to obesity.
B. Insufficient sleep inhibits the natural release of human growth hormone in the human body.
C. Getting the proper amount of uninterrupted sleep plays a major role in the development of muscle.
D. Developing muscle growth is an effective way to stay healthy as we get older.

Correct answer: C

Rationale: The main idea of the passage is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The passage emphasizes how muscle growth occurs during rest periods following a workout, with sleep being a critical time for muscle fiber rebuilding. The connection between sleep, human growth hormone (HGH) release, and muscle development is highlighted. Choice A is incorrect because while the passage mentions the link between inadequate sleep and obesity due to altered appetite hormones, the main focus is on muscle development. Choice B is incorrect because although the passage discusses HGH release during deep sleep, the primary emphasis is on the role of uninterrupted sleep in muscle development. Choice D is incorrect because while the passage acknowledges that developing muscle growth is essential for health as we age, the key point is the significance of uninterrupted sleep in the muscle development process.

2. A reader might infer from this passage that ___________.

A. Obesity can be detrimental to a long life
B. Car crashes are most frequent in the United States
C. The Second Amendment should be overturned
D. People in Asia and Africa have the shortest life spans

Correct answer: A

Rationale: The passage indicates that obesity, along with other health-related issues, contributes to lower life expectancy. This implies that obesity can negatively affect one's lifespan, making option A the correct inference based on the information presented in the text. The other options do not accurately reflect the implications of the passage.

3. 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.

4. As used in the second paragraph, what does the term ubiquitous mean?

A. Indigenous
B. Often ignored
C. Found everywhere
D. Dangerous

Correct answer: C

Rationale: The correct answer is C: 'Found everywhere.' Ubiquitous in this context means widespread presence. In the provided extract, it is mentioned that MRSA bacteria have become ubiquitous not only in hospitals but also in various other settings, indicating they are found everywhere. Choice A, 'Indigenous,' is incorrect as it refers to something native or originating from a specific place, which is not the intended meaning in the context. Choice B, 'Often ignored,' is incorrect as ubiquitous means something that is widely present, not something that is ignored. Choice D, 'Dangerous,' is incorrect as ubiquitous does not directly imply danger, but rather the widespread presence of something.

5. What is the author’s primary purpose in writing this essay about microbes?

A. To persuade
B. To inform
C. To entertain
D. To analyze

Correct answer: B

Rationale: The author's primary purpose is to inform readers about the crucial role of microorganisms in the immune system. The essay focuses on presenting factual information and recent discoveries regarding the impact of microbes on human health. The author aims to educate the readers on the significance of microbes in human health rather than persuade them of a particular viewpoint (Choice A), entertain them with light-hearted content (Choice C), or analyze in-depth data and findings (Choice D). The essay's emphasis on informing readers about the role of microorganisms in the immune system makes 'To inform' the correct choice.
