1. What does the word 'obligatory' mean in the context of the passage on Daylight Savings Time?

A. Approved.
B. Sparse.
C. Requisite.
D. Aberrant.

Correct answer: C

Rationale: In the passage, Daylight Savings Time is presented as something that must be done by law, making it a requirement or something obligatory. 'Requisite' fits this meaning. 'Approved' (choice A) does not convey the sense of necessity as 'obligatory' does. 'Sparse' (choice B) means thinly dispersed and does not relate to the context. 'Aberrant' (choice D) means deviating from the norm, which is not applicable in this context.

2. Why did Strauss set up a net during the construction of the Golden Gate Bridge?

A. For suspension
B. For balance
C. For aesthetics
D. For safety

Correct answer: D

Rationale: Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.

4. Identify the overall tone of the essay about Aromatherapy.

A. Congratulatory.
B. Uncertain.
C. Annoyed.
D. Distressed.

Correct answer: B

Rationale: The tone of the essay is uncertain, as the author questions the validity of aromatherapy based on the study's results. The phrasing "does not necessarily prove that aromatherapy is worthless" indicates a hesitance to fully endorse or dismiss its value. This ambiguity throughout the passage reinforces the uncertain tone, aligning it with choice B.

5. 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.
