1. Which of the following is not listed as a detail in the passage about A Short History of the CDC?

A. Where the organization began.
B. Who first ran the organization.
C. When the organization changed its name.
D. What divisions make up the current CDC.

Correct answer: D

Rationale: The passage does not provide specific details about the divisions that currently make up the CDC. Instead, it focuses on the organization's historical context, original goals, and overall mission. Thus, D is correct as it identifies information not covered in the passage.

2. How were white elephants regarded by the people of Siam?

A. If a village elder received a white elephant, the entire village shared in the supply of meat.
B. White elephants were highly prized as they were very hard workers in the cane fields.
C. The people of Siam vied for the honor of receiving the king's gift or a white elephant.
D. White elephants were a financial burden despite being considered sacred.

Correct answer: C

Rationale: The correct answer is C. In the culture of Siam, white elephants were highly regarded as sacred and receiving one as a gift from the king was considered an honor. It was a symbol of prestige and status to receive the king's gift of a white elephant. Option A is incorrect as white elephants were not used for meat supply. Option B is also incorrect as white elephants were not prized for their work but rather for their symbolic value. Option D is partially correct but does not capture the full significance of white elephants in Siam.

3. 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.

4. What does the word 'suit' mean in the passage about Bridge?

A. A set of clothing to be worn together.
B. Any of the four sets into which a deck of cards is divided.
C. To request or appeal persistently.
D. To be convenient or right for.

Correct answer: B

Rationale: The correct answer is B: 'Any of the four sets into which a deck of cards is divided.' In the context of card games like Bridge, 'suit' refers to one of the four divisions of a deck of cards - spades, hearts, diamonds, or clubs. Each suit contains cards of different ranks, and during the game, players must follow suit if possible, meaning they must play a card of the same suit that was led. This is crucial for understanding card hierarchy and gameplay in Bridge. Choice A is incorrect because it defines 'suit' in terms of clothing, which is not relevant to the context of the passage. Choice C is incorrect as it defines 'suit' as a verb meaning to request persistently, which is unrelated to the card game. Choice D is also incorrect as it defines 'suit' as an adjective meaning to be convenient or right for, which is not the meaning intended in the passage about Bridge.

5. Which sound waves have a higher pitch?

A. Those waves that are closer together
B. Those waves that are farther apart
C. Those waves that travel a long distance
D. Those waves that travel a short distance

Correct answer: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.
