1. 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.

Correct answer: A

Rationale: The passage indicates that obesity, along with other health-related issues, contributes to lower life expectancy.

The other options do not accurately reflect the implications of the passage.

4. What is the meaning of the word moderation as used in the second paragraph?

A. Adequate amounts

Correct answer: A

Rationale: In this context, moderation means consuming adequate amounts of unsaturated fats. The passage highlights that unsaturated fats like olive oil and omega-3 fatty acids are beneficial when consumed in appropriate quantities. Choice B, intervals of time, is incorrect as it does not relate to the consumption of fats. Choice C, excess, is incorrect because moderation implies avoiding excess consumption. Choice D, variation, is unrelated to the context of consuming fats in appropriate amounts.

A. To inform the reader about the stages of the water cycle
B. To explain how rain is formed
C. To persuade readers to preserve water
D. To inform the reader about water's importance in life

Correct answer: A

Rationale: The author's primary purpose for writing this essay is to inform the readers about the stages of the water cycle. The essay explains how water moves through the cycle, including processes like precipitation, runoff, evaporation, and condensation. Choice A is correct because the focus is on educating readers about the water cycle, not just explaining how rain is formed (Choice B), persuading readers to preserve water (Choice C), or discussing water's importance in life (Choice D). The detailed explanation of the water cycle provided in the extract supports the correct answer.
