- A. Causes a deficit in memory, concentration, and attention.
- B. Improves mental alertness.
- C. Boosts concentration levels.
- D. Has no effect on intellectual abilities.
Correct answer: A
Rationale: Insomnia affects intellectual abilities by causing a deficit in memory, concentration, and attention. The passage highlights that lack of sleep impacts memory, attention, and concentration, leading to feelings of irritation or depression. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not align with the negative impact insomnia has on intellectual abilities as described in the passage.
2. 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.

Rationale: The tone of the essay is appreciative, reflecting a recognition of the CDC's historical contributions to public health.

- 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 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.
