1. How does insomnia affect intellectual abilities?

• 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. Which claim from the passage best describes the benefits of nanotechnology?

• A. Scientists can develop novel technologies and products.
• B. Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers.
• C. The different colors can be used in simple medical tests to indicate infection or disease.
• D. Unique properties of materials emerge.

Correct answer: D

Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.

3. What is the best title for the passage on bicycles?

• A. Bicycles Are Better.
• B. Cycle Your Way to Fitness.
• C. A Ride through the History of Bicycles.
• D. The Popularity of Bicycles.

Correct answer: C

Rationale: The correct answer is C: 'A Ride through the History of Bicycles.' This title best captures the passage's focus on the historical development and evolution of the bicycle from its invention to its modern form. Choice A, 'Bicycles Are Better,' is too general and doesn't encompass the historical aspect discussed in the passage. Choice B, 'Cycle Your Way to Fitness,' focuses solely on the fitness aspect of bicycles, ignoring the broader historical context. Choice D, 'The Popularity of Bicycles,' touches on one aspect but does not encompass the comprehensive historical journey presented in the passage.

4. What is stated in the passage about Sleep Apnea?

• A. Sleep apnea causes chronic illness.
• B. Sleep apnea affects intellectual abilities.
• C. Sleep apnea leads to early death.
• D. Sleep apnea causes breathing interruptions.

Correct answer: D

Rationale: The correct answer is 'D: Sleep apnea causes breathing interruptions.' The passage explicitly mentions sleep apnea as a condition where an individual stops breathing during sleep, indicating breathing interruptions. Choice A is incorrect because the passage does not directly state that sleep apnea causes chronic illness. Choice B is incorrect because the passage discusses how lack of sleep affects intellectual abilities but does not specifically attribute this to sleep apnea. Choice C is incorrect as the passage does not mention sleep apnea leading to early death. Therefore, the most accurate statement about sleep apnea based on the passage is that it causes breathing interruptions.

5. The word lethargy as used in the second paragraph of the passage can best be defined as ___________.

• A. Sluggishness
• B. Irritability
• C. Energy
• D. Starvation

Correct answer: A

Rationale: In this context, 'lethargy' refers to a state of sluggishness or lack of energy. The passage mentions that people with seasonal affective disorder (SAD) struggle with lethargy and chronic fatigue, impairing their daily lives. Therefore, the correct definition of 'lethargy' in this context is 'sluggishness.' Choice B, 'Irritability,' is incorrect as lethargy refers more to a lack of energy than to being irritable. Choice C, 'Energy,' is the opposite of lethargy. Choice D, 'Starvation,' is unrelated to the definition of lethargy in this context.
