A. Encourage overeating.
B. Criticize healthy eating habits.

Correct answer: C

Rationale: The author's motive for writing the paragraph is to urge self-control. The text emphasizes the importance of moderation in food and drink consumption to avoid serious physical and mental health problems. It highlights the negative consequences of overeating and alcohol abuse, pointing out the strain on the heart, diabetes risk, shortened lifespan, and emotional eating habits. By discussing the issues related to overconsumption, the author aims to promote self-control and responsible habits.

3. What is the main idea of the passage about MRSA?

A. Methicillin-resistant Staphylococcus aureus (MRSA) is a significant problem both within and outside of hospitals, and there are ways to mitigate the risk.
B. A new textile made of nanomaterials could significantly reduce the spread of hospital-associated MRSA infections.
C. There are multiple strains of MRSA, and they pose various risks beyond just fatality.
D. MRSA is a significant problem both within and outside of hospitals, but there are ways to mitigate the risk.

Correct answer: D

Rationale: The main idea of the passage is that MRSA is a significant issue both within and outside of hospitals. It highlights the challenges posed by MRSA, including its resistance to antibiotics, high mortality rates, and widespread presence in various settings. While the development of new technologies like nanomaterial textiles shows promise in reducing hospital-associated MRSA, the passage also emphasizes the importance of practicing good hygiene to prevent community-associated MRSA infections. Choices A, B, and C are incorrect because they do not capture the comprehensive overview of MRSA provided in the passage. Choice A encompasses the main idea by emphasizing the significance of MRSA and ways to mitigate the risk. Choice B focuses on a specific solution rather than the broader issue of MRSA. Choice C is incorrect as it oversimplifies the risks associated with MRSA strains by only mentioning fatality.

4. What role does water vapor play in the Water Cycle, as described in the passage?

A. Water vapor is unnecessary in the water cycle.
B. Water vapor plays a key role in precipitation.
C. Water vapor is harmful to the environment.
D. Water vapor cools the Earth's surface.

Correct answer: B

Rationale: The correct answer is B: 'Water vapor plays a key role in precipitation.' The passage clearly outlines the importance of water vapor in the water cycle. It explains that water vapor returns to the air from surface water and plants, and condenses back into droplets of liquid, forming clouds. These clouds eventually lead to precipitation like rain, snow, sleet, or hail. Choice A is incorrect as water vapor is crucial in the water cycle. Choice C is also incorrect as there is no mention of water vapor being harmful in the passage. Choice D is incorrect as the passage does not state that water vapor cools the Earth's surface; instead, it highlights its role in the formation of precipitation.
