1. 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.

2. Which statement would not be inferred by the reader in the passage about Super Foods?

• A. Instant oatmeal can be part of a healthful breakfast.
• B. Blueberries are an especially healthful food.
• C. Certain grains and dairy products are super foods.
• D. Super foods are more expensive than processed foods.

Correct answer: D

Rationale: The passage does not imply or provide information regarding the cost of superfoods compared to processed foods. Therefore, D is the correct answer, as it identifies a statement that cannot be inferred from the passage.

3. What is the author’s primary purpose in writing the essay about Concussions?

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

Correct answer: D

Rationale: The primary purpose of the essay is to inform the reader about concussions, their effects, and recovery. While analysis may be involved in the presentation, the overarching goal is to provide information, making A the most accurate answer.

4. What is implied by this paragraph about food and drink?

• A. We should eat and drink in reasonable quantities.
• B. Alcohol should be banned.
• C. People should eat in large quantities.
• D. We need stronger laws to control drunk drivers.

Correct answer: A

Rationale: The paragraph emphasizes that while food and drink are necessary and desirable, their abuse can lead to serious physical and mental problems. It highlights the negative consequences of overeating and alcohol abuse, such as strain on the heart, diabetes, and other health issues. The text suggests the importance of moderation in consumption to prevent health problems. Choices B, C, and D are incorrect because the paragraph does not call for a ban on alcohol, promote eating in large quantities, or specifically discuss the need for stronger laws to control drunk drivers.

5. What is the relationship between the tilt of the Earth and seasons as explained in the passage on Daylight Savings Time?

• A. The tilt of the Earth has no effect on seasons.
• B. The tilt of the Earth creates seasons.
• C. The tilt of the Earth changes throughout the year.
• D. The tilt of the Earth is random and unpredictable.

Correct answer: B

Rationale: The correct answer is B: 'The tilt of the Earth creates seasons.' The passage explains that the tilt of the Earth causes the different seasons by changing the amount of sunlight different regions receive. This tilt results in varying angles at which sunlight reaches different parts of the Earth, leading to the seasonal changes in temperature and daylight hours. Choice A is incorrect because the passage clearly states that the tilt of the Earth does have an effect on the seasons. Choice C is incorrect because the tilt of the Earth remains relatively constant throughout the year. Choice D is incorrect as the tilt of the Earth is not random but follows a consistent pattern.
