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.

Which sound waves have a higher pitch?

• A. Those waves that are closer together
• B. Those waves that are farther apart
• C. Those waves that travel a long distance
• D. Those waves that travel a short distance

Correct Answer: A
Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.

What is the author's main argument in the passage on the Electoral College?

• A. The Electoral College ensures that all states have a say in elections.
• B. The Electoral College is outdated and needs reform.
• C. The Electoral College should be abolished.
• D. The Electoral College was created to favor larger states.

Correct Answer: B
Rationale: The correct answer is B: 'The Electoral College is outdated and needs reform.' The passage discusses the Electoral College system, highlighting its complexities and the discrepancy between the popular vote and electoral vote outcomes. It mentions the confusion and the case of the 2000 election where the popular vote winner did not become president. The main argument is that the system is outdated and requires reforms to align with modern democratic principles. Choice A is incorrect as the passage does not focus on ensuring all states have a say but rather on the need for reform. Choice C is not the main argument presented in the passage; while the passage mentions confusion, it does not explicitly call for abolition. Choice D is incorrect as the passage does not state that the Electoral College was created to favor larger states; instead, it discusses the allocation of electoral votes based on Congressional representation and population.

What does the word 'integral' mean as used in the first paragraph of the passage?

• A. Central
• B. Initial
• C. Trifling
• D. Irrelevant

Correct Answer: A
Rationale: In this context, 'integral' means 'central' or essential. The passage discusses the debate around spanking as a method of discipline. Some parents consider it an integral part of teaching right and wrong, highlighting its central importance. Therefore, the correct answer is 'A: Central.' Choice B, 'Initial,' is incorrect as the word 'integral' does not refer to something being at the beginning of a process or sequence. Choice C, 'Trifling,' is incorrect as 'integral' implies significance and importance, opposite to being trivial. Choice D, 'Irrelevant,' is incorrect as the passage clearly states that some parents view spanking as essential, making it relevant and not irrelevant.

What is implied by this paragraph about food and drink?

• A. We should eat and drink in reasonable quantities.
• B. Alcohol should be banned.
• C. People should eat in large quantities.
• D. We need stronger laws to control drunk drivers.

Correct Answer: A
Rationale: The paragraph emphasizes that while food and drink are necessary and desirable, their abuse can lead to serious physical and mental problems. It highlights the negative consequences of overeating and alcohol abuse, such as strain on the heart, diabetes, and other health issues. The text suggests the importance of moderation in consumption to prevent health problems. Choices B, C, and D are incorrect because the paragraph does not call for a ban on alcohol, promote eating in large quantities, or specifically discuss the need for stronger laws to control drunk drivers.
