1. What conclusion can the reader draw after reading the passage about The Sleep Workout?

A. Getting uninterrupted sleep is more important than getting enough sleep.
B. Insufficient sleep may result in an increased risk for obesity.
C. Human growth hormone is not essential for muscle development.
D. Leptin is essential for building muscle.

Correct answer: B

Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.

2. What is the best summary of this passage?

A. The heart regulates oxygen flow and waste disposal, with the kidneys aiding in salt and water absorption.
B. The cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys.
C. Baroreceptors send impulses to regulate blood pressure by affecting the heart, arteries, and veins.
D. Chemoreceptors monitor oxygen levels to impact blood pressure.

Correct answer: B

Rationale: The correct answer is B because it provides a comprehensive summary of the passage, explaining how the cardiovascular system regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys. Choice A is incorrect as it only focuses on the heart and kidneys without mentioning the broader cardiovascular system. Choice C is incorrect as it solely emphasizes the role of baroreceptors in regulating blood pressure. Choice D is incorrect as it oversimplifies the role of chemoreceptors in monitoring oxygen levels without mentioning their impact on blood pressure regulation.

3. As used in the last sentence of this paragraph, the term 'concomitant' means?

A. Accompanying
B. Quiet
C. Frustrated
D. Prefer low-pitched tones

Correct answer: A

Rationale: In the provided extract, the term 'concomitant' is used to describe problems associated with alcohol abuse, such as the individual becoming alcoholic, contribution to highway deaths by drunken drivers, and spousal and child abuse. Therefore, in this context, 'concomitant' means accompanying, or going along with something else. The other choices of 'Quiet,' 'Frustrated,' and 'Prefer low-pitched tones' do not align with the meaning of 'concomitant' as used in the paragraph.

4. Why was receiving a white elephant considered a burden in ancient Siam?

A. People tried to avoid receiving it, as it was a burden.
B. It was a symbol of honor and wealth.
C. It was used in ceremonial processes.
D. The people greatly desired a white elephant as a gift.

Correct answer: A

Rationale: Receiving a white elephant in ancient Siam was considered a burden because the animal, being sacred, couldn't be used for work like other elephants. The recipient had to bear the cost of feeding the elephant large amounts of fruit and maintaining it in a lavish manner. The ruler's displeasure if the gift was not accepted graciously added to the pressure. This financial strain often led recipients to financial ruin. Therefore, people tried to avoid receiving a white elephant to prevent these financial consequences. Choice B is incorrect because the white elephant was not considered a symbol of honor and wealth but rather a burden. Choice C is incorrect as the white elephant was not primarily used in ceremonial processes but was a gift that came with financial responsibilities. Choice D is incorrect as the passage does not mention that people greatly desired a white elephant as a gift, but rather the opposite.

5. What role does water vapor play in the Water Cycle, as described in the passage?

A. Water vapor is unnecessary in the water cycle.
B. Water vapor plays a key role in precipitation.
C. Water vapor is harmful to the environment.
D. Water vapor cools the Earth's surface.

Correct answer: B

Rationale: The correct answer is B: 'Water vapor plays a key role in precipitation.' The passage clearly outlines the importance of water vapor in the water cycle. It explains that water vapor returns to the air from surface water and plants, and condenses back into droplets of liquid, forming clouds. These clouds eventually lead to precipitation like rain, snow, sleet, or hail. Choice A is incorrect as water vapor is crucial in the water cycle. Choice C is also incorrect as there is no mention of water vapor being harmful in the passage. Choice D is incorrect as the passage does not state that water vapor cools the Earth's surface; instead, it highlights its role in the formation of precipitation.
