1. What is the meaning of the word duration as used in the last paragraph?

• A. Basis
• B. Extent
• C. Cure
• D. Solidity

Correct answer: B

Rationale: The word "duration" in the context of sleep refers to the length of time that children should sleep. It suggests a focus on the amount of sleep necessary for healthy development, making option B the correct choice as it aligns with the emphasis on recommended sleep hours for children.

2. What is the author’s primary purpose in writing the essay about High Fructose Corn Syrup?

• A. To inform.
• B. To persuade.
• C. To entertain.
• D. To analyze.

Correct answer: A

Rationale: The correct answer is A: 'To inform.' The essay provides detailed information about High Fructose Corn Syrup (HFCS), discussing its impact on health, how it is derived, its link to health issues like obesity, and the ongoing debates surrounding its consumption and health implications. The primary goal of the author is to educate the readers about HFCS and its effects, rather than persuade them to take a particular stance (choice B), entertain them (choice C), or analyze the topic in depth (choice D). The essay presents facts, studies, and expert opinions to inform the audience about the controversies and health risks associated with HFCS consumption, aiming to enhance the readers' knowledge and understanding of this sweetener's implications on health.

3. What is stated in the passage about the Olympic Games?

• A. The Olympic Games are held every four years.
• B. The Olympic Games are often postponed.
• C. The Olympic Games are held only in leap years.
• D. The Olympic Games only involve certain countries.

Correct answer: A

Rationale: The correct answer is A: 'The Olympic Games are held every four years,' as stated in the passage. The extract explicitly mentions that the Summer Olympic Games are held every four years. Choice B is incorrect as there is no mention of the Olympic Games being often postponed in the passage. Choice C is incorrect because although the Olympic Games occur during leap years, they are not exclusively held only in leap years. Choice D is incorrect as there is no indication in the passage that the Olympic Games only involve certain countries.

4. What is a major difference in the way baroreceptors and chemoreceptors work from the way the kidneys work?

• A. Baroreceptors and chemoreceptors send impulses from the arteries, while the kidneys control blood volume.
• B. Baroreceptors and chemoreceptors both work to help maintain blood volume, whereas the kidneys take care of salts, water, and waste removal.
• C. Baroreceptors and chemoreceptors must work together to control blood pressure, whereas the kidneys work with the adrenal cortex.
• D. Baroreceptors and chemoreceptors are both located near the adrenal cortex, whereas the kidneys are located near the heart.

Correct answer: A

Rationale: The correct answer is A. Baroreceptors and chemoreceptors send impulses from the arteries, while the kidneys control blood volume. Baroreceptors and chemoreceptors are responsible for monitoring blood pressure by sensing changes in pressure, oxygen levels, carbon dioxide levels, and pH within the arteries. They send out impulses to raise or lower blood pressure accordingly. On the other hand, the kidneys play a crucial role in regulating blood volume by absorbing salts and water and removing waste products. This key difference highlights that while baroreceptors and chemoreceptors are involved in monitoring and regulating blood pressure, the kidneys primarily focus on controlling blood volume. Choice B is incorrect because it inaccurately states that baroreceptors and chemoreceptors help maintain blood volume, which is not their primary function. Choice C is incorrect as it provides an inaccurate comparison between the roles of baroreceptors, chemoreceptors, and the kidneys. Choice D is incorrect as it wrongly associates the location of baroreceptors and chemoreceptors with the adrenal cortex, which is not accurate.

5. What does the passage about the Water Cycle explain?

• A. The water cycle consists of precipitation, evaporation, and condensation.
• B. The water cycle is a continuous process of recycling water on Earth.
• C. Rain is the most important part of the water cycle.
• D. Evaporation is the final step in the water cycle.

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, starting with precipitation (rain, snow, sleet, or hail) falling to the ground, followed by runoff, evaporation transforming liquid water into water vapor, and finally condensation turning water vapor back into liquid. Choice B is incorrect because it is too broad and doesn't specifically address the stages of the water cycle. Choice C is incorrect as rain is just one part of the water cycle and not the most important. Choice D is incorrect as evaporation is not the final step but one of the stages of the water cycle.
