1. What is the main idea of the passage on Daylight Savings Time?
- A. Daylight Savings Time helps save energy.
- B. Daylight Savings Time is unnecessary and outdated.
- C. Daylight Savings Time is a law to conserve energy during wars.
- D. Daylight Savings Time was first implemented in Germany.
Correct answer: A
Rationale: The correct answer is A: "Daylight Savings Time helps save energy." The passage explains how Daylight Savings Time is implemented to take advantage of more daylight, which results in energy savings. By adjusting clocks ahead in spring, people can make use of additional daylight in the evenings, leading to reduced energy consumption. This measure was introduced to address energy crises and has been shown to save significant amounts of energy. Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits. Choice C is partially correct but not the main idea of the passage, as saving energy is the primary focus. Choice D is mentioned in the passage but is not the main idea; the main idea is about the purpose and benefits of Daylight Savings Time.
2. 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.
3. The main idea of the passage is ___________.
- A. The CDC keeps an eye out for new potentially threatening health issues
- B. Children require several more hours of sleep per night than adults do
- C. More people are staying up at night to surf the Internet or watch television
- D. Lack of adequate sleep is becoming a major national health problem
Correct answer: D
Rationale: The main idea of the passage is that lack of adequate sleep is becoming a major national health problem.
4. 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.
5. Which of the following describes the purpose of the passage?
- A. To describe the causes of cystic fibrosis
- B. To explain how cystic fibrosis is passed down through families
- C. To provide an overview of CF and how it is inherited
- D. To review why some Americans have CF, but others do not
Correct answer: C
Rationale: The correct answer is C. The passage aims to provide an overview of cystic fibrosis (CF) and how it is inherited. It explains that CF is passed down through families due to a defective gene, detailing how this gene affects the body and who is most commonly affected by the disease. Choices A, B, and D are incorrect because the passage does not solely focus on describing the causes of CF, explaining how it is passed down through families, or reviewing why some Americans have CF while others do not. Instead, it provides a broader perspective on CF and its inheritance.
