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. What is the best definition of 'efficient' as used in the third paragraph?

A. Slow but steady.
B. Productive without waste.
C. Wasteful and careless.
D. Quick but sloppy.

Correct answer: B

Rationale: The correct definition of 'efficient' in the third paragraph is 'Productive without waste.' In the extract provided, it discusses how different cultures developed tools like cutlery and chopsticks to efficiently eat food. Efficiency here refers to getting something done with the least amount of waste. Choices A, C, and D are incorrect because they do not accurately capture the concept of efficiency discussed in the passage.

3. Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?

A. HFCS and sugar share a biological structure.
B. HFCS is cheaper to use than sugar.
C. HFCS is now used to sweeten a variety of products.
D. HFCS contains more calories than aspartame.

Correct answer: D

Rationale: The correct answer is D because the passage does not mention that HFCS contains more calories than aspartame. While the passage discusses the concerns and implications of high fructose corn syrup (HFCS), it does not compare its caloric content to aspartame. Detail A is supported by the passage as both HFCS and sugar share a biological structure. Detail B is also mentioned in the passage, stating that HFCS is cheaper to use than sugar. Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.

4. What is the best summary of the passage?

A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.

5. 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.
