1. What is the meaning of the word satiety as used in the last paragraph about The Sleep Workout?

A. A state of tiredness.
B. A state of being satisfied.
C. A state of being overloaded.
D. A state of confusion.

Correct answer: B

Rationale: Satiety refers to a state of being satisfied, particularly in terms of appetite. In the context of the excerpt provided, it explains that individuals who lack adequate sleep may experience lowered levels of leptin, a hormone that controls appetite. As a result, even after meeting their caloric needs, they may still crave carbohydrates, indicating a lack of satisfaction or satiety. This can lead to obesity and disrupt healthy eating habits. Therefore, choice B, 'A state of being satisfied,' is the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the meaning of satiety in the context of appetite regulation and sleep's impact on food cravings.

2. In the context of the passage, 'accommodate' means to

A. Arrange lodging for
B. Contain
C. Make allowances for
D. Excuse

Correct answer: C

Rationale: In this context, 'accommodate' means to make allowances for different focal points of vision. The passage explains that the function of the lens is to adjust for different focal points so that sensory data can be correctly directed to the retina for interpretation into images by the brain. This aligns with the meaning of 'make allowances for' as it indicates adapting to or accommodating different needs or requirements. Choices A, B, and D are incorrect because in the context of the passage, 'accommodate' specifically refers to adjusting for different focal points of vision rather than arranging lodging, containing, or excusing.

3. The author suggests that persistent passivity and imperturbability may be a direct result of which of the following?

A. Drug-induced stimulation of the amygdala.
B. A stroke that resulted in severe tissue damage in the limbic system.
C. Encephalitis as a result of head trauma.
D. Activation of a strategically implanted electrode in a patient’s amygdala.

Correct answer: B

Rationale: The correct answer is B. The passage highlights that damage to the limbic system, specifically the amygdala, can lead to passivity and lack of aggression. This is supported by the statement that patients with trauma or damage to the amygdala exhibit a complete absence of aggression. Thus, a stroke causing severe tissue damage in the limbic system, including the amygdala, can result in persistent passivity and imperturbability. Choices A, C, and D are incorrect because they do not directly relate to damage in the limbic system, which is specifically mentioned in the passage as the cause of the described behaviors.

4. A reader might infer from this passage that the organization ___________.

A. succeeded in eradicating malaria
B. has always been led by a medical doctor
C. no longer studies communicable diseases
D. changed its name to match its mission

Rationale: The passage never says whether or not the CDC succeeded in its original mission (choice A) or whether it continued to be led by doctors (choice B). Inferring either of those things would be a leap unsupported by the text. Choice C is countered by information in the final

5. What is the meaning of the word overturn in the last paragraph of the passage?

A. Justify
