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 of the following is not mentioned as a detail in the passage about Sickle-Cell Anemia?

• A. People of South American or African descent may be prone to sickle-cell anemia.
• B. Symptoms of sickle-cell anemia may include sudden occurrences of extreme abdominal and back pain.
• C. The red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes.
• D. Vitamin and mineral deficiencies may result in some anemia.

Correct answer: D

Rationale: The correct answer is D because the passage does not mention anything about vitamin and mineral deficiencies in relation to sickle-cell anemia. Choice A is incorrect as the passage specifies that sickle-cell anemia is more common among people of South American or African descent. Choice B is correct as the passage states that symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain. Choice C is correct as the passage describes that the red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes. The passage does not discuss any relationship between vitamin and mineral deficiencies and sickle-cell anemia, making choice D the correct option.

3. Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?

• A. HFCS and sugar share a biological structure.
• B. HFCS is cheaper to use than sugar.
• C. HFCS is now used to sweeten a variety of products.
• D. HFCS contains more calories than aspartame.

Correct answer: D

Rationale: The correct answer is D because the passage does not mention that HFCS contains more calories than aspartame. While the passage discusses the concerns and implications of high fructose corn syrup (HFCS), it does not compare its caloric content to aspartame. Detail A is supported by the passage as both HFCS and sugar share a biological structure. Detail B is also mentioned in the passage, stating that HFCS is cheaper to use than sugar. Detail C is supported by the text, which mentions that HFCS is now used to sweeten a variety of products. However, detail D is never discussed in the passage, making it the correct answer.

4. What conclusion can the reader draw after reading the passage about The Sleep Workout?

• A. Getting uninterrupted sleep is more important than getting enough sleep.
• B. Insufficient sleep may result in an increased risk for obesity.
• C. Human growth hormone is not essential for muscle development.
• D. Leptin is essential for building muscle.

Correct answer: B

Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.

5. How does the author want the reader to feel after reading about Bridge?

• A. As though the game of Bridge is too hard for novices to learn
• B. Frustrated and confused about playing bridge
• C. Confident and excited about learning Bridge
• D. Overwhelmed by all the rules for the game of Bridge

Correct answer: C

Rationale: The author wants the reader to feel confident and excited about learning the game of Bridge. In the text, the author acknowledges that Bridge can be complicated for beginners but emphasizes that with time, effort, and a good teacher, even novices can become proficient. The tone of the writing is encouraging and informative, providing tips and explanations to help the reader understand the game better and increase their interest in playing Bridge. Choices A, B, and D are incorrect because the text does not convey that the game is too hard for novices, aims to frustrate or confuse the reader, or overwhelm them with rules. Instead, the author's intention is to inspire confidence and excitement in learning this exciting card game.
