1. What statement about jetlag can be inferred from the passage on Daylight Savings Time?
- A. Jetlag is caused by flying at high speeds.
- B. Jetlag is caused by moving between time zones.
- C. Jetlag is unrelated to time zone changes.
- D. Jetlag is a myth.
Correct answer: B
Rationale: The correct answer is B: 'Jetlag is caused by moving between time zones.' The passage explains that jetlag occurs when moving suddenly from one time zone to another, such as when flying from Asia to North America. This disrupts the body's internal clock, leading to symptoms like tiredness and sleep disturbances. Choice A is incorrect as jetlag is not attributed to high-speed travel but to time zone changes. Choice C is incorrect as the passage clearly links jetlag to changes in time zones. Choice D is incorrect as jetlag is a real phenomenon experienced by individuals who travel across different time zones.

- A. There are many positive effects of receiving direct exposure to sunlight.
- B. The negative impacts of sunlight should not be ignored.
- C. Vitamin D is integral for maintaining healthy bones and preventing diseases.
- D. Vitamin D is synthesized by our bodies in reaction to direct sunlight.
Correct answer: A
Rationale: The passage primarily discusses the various positive effects of sunlight exposure, particularly highlighting the benefits of vitamin D for bone health and the regulation of circadian rhythms. While it acknowledges the negative impacts of excessive sun exposure, the emphasis is on the positive aspects, making A the main idea of the passage.

Correct answer: C
Rationale: The author's primary purpose in writing the essay is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. Choice A is incorrect because there is no attempt to persuade the reader to have an ECG. Choice B is incorrect because the essay is focused on providing information rather than entertaining with a heartwarming story. Choice D is incorrect as the essay does not primarily analyze the difference between the SA node and the AV node; instead, it focuses on explaining how an electrocardiograph reads electric currents from the heart.
