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.

2. Which of the following statements is an opinion related to Hypertension?

A. Obese people are at risk for hypertension.
B. Losing weight can decrease blood pressure.
C. Older people must pay attention to their blood pressure.
D. Blurred vision or dizziness may be a sign of hypertension.

Correct answer: C

Rationale: A statement of fact can be proved or checked. A statement of opinion is what someone thinks or believes. In this case, statements A, B, and D could be proved scientifically, but statement C is simply a suggestion. While it is advisable for older people to monitor their blood pressure due to the increased risk associated with aging, the statement itself is an opinion because it suggests what older people 'must' do, which is a subjective viewpoint rather than a verifiable fact. Statements A, B, and D provide factual information supported by scientific evidence, making them statements of fact rather than opinion.

4. Which might be a good title for this passage about Barefoot Running?

A. Everyone Should Run Barefoot
B. How to Prevent Running Injuries
C. Modern Road Surfaces Versus Barefoot Running

5. Which of the following is not listed as a detail in the passage about microbes?

A. Babies are born coated with germs from the birth canal.
B. Mice and humans respond to microbes differently.
C. Few people share the same microbes in the same quantities.
D. Human bodies contain far more microbes than they do cells.

Correct answer: B

Rationale: The correct answer is B because the passage does not detail that mice and humans respond to microbes differently. The passage discusses how laboratory mice required a particular strain of bacteria to help their immune systems function correctly, indicating a difference in how mice and humans respond to microbes. Choices A, C, and D are all details mentioned in the passage: A discusses babies being coated with germs from the birth canal, C talks about the variation in microbes among individuals, and D states that human bodies contain more microbes than cells.
