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. Identify the overall tone of the essay about Sunny-Side Up.

A. Confused.
B. Confident.
C. Disheartened.
D. Disapproving.

Correct answer: B

Rationale: The overall tone of the essay is confident, as the author articulates the positive effects of sunlight and presents a well-supported argument. The assertive language used throughout reflects a strong belief in the benefits of sunlight, making B the correct answer.

3. Which of the following is a conclusion that a reader can draw from this passage?

A. Humans are not the only mammals that exhibit symptoms when infected by Borrelia burgdorferi.
B. The life cycle of an uninfected tick includes a dormant phase before the nymph stage, which is not excluded.
C. Unless a tick feeds on an infected mouse or squirrel, it will not spread Lyme disease.
D. The combination of fever, headache, and joint pain is not a definite indication of Lyme disease.

Correct answer: C

Rationale: The correct answer is C. The passage clearly states that for Lyme disease to spread, a tick must feed on an infected host, such as a mouse or squirrel. This conclusion can be drawn from the information provided in the extract. Choice A is incorrect because the passage does not specify that humans are the only mammals that exhibit symptoms when infected by Borrelia burgdorferi. Choice B is incorrect as the passage mentions that the life cycle of an uninfected tick includes a dormant phase before the nymph stage, without excluding it. Choice D is incorrect because the passage does not state that the combination of fever, headache, and joint pain is a definitive sign of Lyme disease.

4. What statement can be implied from the content of the article?

A. Diversity is interesting to learn about.
B. Everyone should learn to use chopsticks.
C. European methods of eating are the best.
D. Space travel has made eating easier.

Correct answer: A

Rationale: The correct statement that can be implied from the content of the article is that diversity is interesting to learn about. The passage discusses different cultural methods of eating, highlighting the value of discovering these differences and learning new ways to do things. Choice B is incorrect as it focuses on a specific eating tool without capturing the broader message of cultural diversity. Choice C is incorrect as it suggests a superiority of European methods without considering the value of diversity. Choice D is incorrect as the passage mentions that space travel has created new challenges for consuming food, not necessarily making eating easier.

5. The author suggests that persistent passivity and imperturbability may be a direct result of which of the following?

A. Drug-induced stimulation of the amygdala.
B. A stroke that resulted in severe tissue damage in the limbic system.
C. Encephalitis as a result of head trauma.
D. Activation of a strategically implanted electrode in a patient’s amygdala.

Correct answer: B

Rationale: The correct answer is B. The passage highlights that damage to the limbic system, specifically the amygdala, can lead to passivity and lack of aggression. This is supported by the statement that patients with trauma or damage to the amygdala exhibit a complete absence of aggression. Thus, a stroke causing severe tissue damage in the limbic system, including the amygdala, can result in persistent passivity and imperturbability. Choices A, C, and D are incorrect because they do not directly relate to damage in the limbic system, which is specifically mentioned in the passage as the cause of the described behaviors.
