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. What conclusion can a reader draw about the connection between sleep and young children?

• A. Lack of sleep causes children to fail in school.
• B. Inadequate rest raises the risk of behavioral and physical problems.
• C. Sleeping less than 10 hours a night is guaranteed to result in obesity.
• D. Eight hours of sleep each night meets the requirements of most children.

Correct answer: B

Rationale: The study outlined in the passage indicates that children who lack adequate sleep are at a higher risk for behavioral and physical issues, such as obesity and attention disorders. This conclusion is derived from the evidence provided in the passage, suggesting a direct link between sleep deprivation and negative outcomes, thus supporting option B..

3. 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.

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

The organization acts as a monitor in healthcare settings, which aligns with the definition of a watchdog, confirming that option B is correct.

5. What statement from the article is correct?

• A. Chopsticks were developed in Europe.
• B. China developed chopsticks for eating utensils.
• C. Eating with forks is difficult.
• D. Space travel eliminated the need for utensils.

Correct answer: B

Rationale: The correct answer is B. The passage clearly states that China developed chopsticks as an efficient tool for eating, making choice B the correct statement. Choice A is incorrect as chopsticks were not developed in Europe but in China. Choice C is not supported by the passage as it does not discuss the difficulty of eating with forks. Choice D is also incorrect as space travel introduced new challenges but did not eliminate the need for utensils.
