1. Why does the author mention 'impact craters' in line 16?

• A. To explain the corrosive effects of atmospheric weathering
• B. To explain why the Moon has no plant life because of meteorites
• C. To show the result of the Moon not having an atmosphere
• D. To show the result of the Moon not having active tectonic or volcanic activity

Correct answer: C

Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.

2. Choose the best summary of the passage about microbes.

• A. Scientists have discovered the importance of certain bacteria for a well-functioning immune system, especially in defending against pathogens. The colonization of microbes in the body begins at birth, with the immune system relying on these bacteria for proper function.
• B. The passage discusses the role of bacteria in the development of the human immune system. It highlights that the body supports various microorganisms crucial for immunity, starting from birth. The presence of harmless bacteria is essential for the immune system to work effectively.
• C. The body hosts a vast number of microorganisms critical for immune system development. Harmless bacteria are necessary for the immune system to defend against pathogens effectively. Early research shows promising results in fecal bacteriotherapy for restoring the immune system's ability to fight off harmful invaders.
• D. Microbes play a pivotal role in human health, particularly in immune system development. The introduction of healthy bacteria is essential for the immune system to function correctly. Fecal bacteriotherapy is a novel approach to reintroducing beneficial bacteria into a compromised colon to enhance immune response.

Correct answer: C

Rationale: The correct answer is C. The passage emphasizes the importance of certain bacteria for a properly functioning immune system. It discusses how harmless bacteria play a crucial role in defending the body against pathogens. Choice A is incorrect as it focuses on the immune system's response to certain types of bacteria in lower organisms, not the overall importance of bacteria for immunity. Choice B is incorrect as it mainly discusses bacteriotherapy in relation to the reconstruction of a damaged colon, rather than the broader role of bacteria in immune system health. Choice D is incorrect as it only talks about the process of replacing harmful bacteria with harmless ones, missing the key point about the necessity of certain bacteria for immune system function.

3. What is the main idea of the passage?

• A. Senior citizens need to increase their calcium and vitamin D intake.
• B. The food pyramid was revised to reflect the needs of seniors.
• C. Physical activity is a new addition to the food pyramid.
• D. The revised food pyramid looks more like a food square.

Correct answer: B

Rationale: The passage discusses the revision of the food pyramid specifically to address the unique dietary needs of seniors. It emphasizes how the changes were made based on ongoing research and analysis, indicating a broader focus on senior nutrition rather than just individual nutrients or exercise. Thus, option B captures the essence of the passage as it succinctly summarizes the main idea.

4. What is the meaning of the word respite as used in the first paragraph?

• A. Relief
• B. Treatment
• C. Guardian
• D. Specialist

Correct answer: A

Rationale: In this context, 'respite' refers to relief, providing caregivers with temporary rest or a break from their caregiving duties. The word 'respite' is associated with giving caregivers a brief period of relief, not with treatment, guardianship, or specialization. The extract mentions 'respite services' along with caregiver services, indicating that respite is a form of support or relief for caregivers.

5. What is the main idea of the passage about Super Foods?

• A. Super foods are low in calories but provide essential nutrients that have enormous health benefits.
• B. U.S. supermarkets should make a point of stocking up on powerful super foods.
• C. Blueberries are a super food that contains a natural inflammatory as well as important vitamins and minerals.
• D. Doctors now believe that daily inclusion of super foods in the diet can reverse the aging process.

Correct answer: A

Rationale: The main idea emphasizes that superfoods are low in calories yet rich in essential nutrients that provide significant health benefits. This statement captures the overall essence of the passage, while the other options focus too narrowly or introduce unsupported claims, making A the correct answer.
