1. What is the author’s primary purpose in writing this essay about microbes?

• A. To persuade
• B. To inform
• C. To entertain
• D. To analyze

Correct answer: B

Rationale: The author's primary purpose is to inform readers about the crucial role of microorganisms in the immune system. The essay focuses on presenting factual information and recent discoveries regarding the impact of microbes on human health. The author aims to educate the readers on the significance of microbes in human health rather than persuade them of a particular viewpoint (Choice A), entertain them with light-hearted content (Choice C), or analyze in-depth data and findings (Choice D). The essay's emphasis on informing readers about the role of microorganisms in the immune system makes 'To inform' the correct choice.

2. What is the overall tone of the essay?

• A. Informative
• B. Insensitive
• C. Grim
• D. Uplifting

Correct answer: C

Rationale: The passage discusses the challenges and symptoms associated with sickle-cell anemia, portraying a somber and serious tone. The descriptions of persistent pain, difficulties, and the impact on individuals' lives make the overall tone fairly grim. The essay focuses on the hardships faced by individuals with sickle-cell anemia, highlighting the severity of the disease. Choices A, B, and D are incorrect because the tone of the essay is not informal, insensitive, or uplifting. It is important to consider the language used, the subject matter, and the overall emotional impact of the text to determine the tone accurately.

3. Which of the following describes the purpose of the passage?

• A. To describe the causes of cystic fibrosis
• B. To explain how cystic fibrosis is passed down through families
• C. To provide an overview of CF and how it is inherited
• D. To review why some Americans have CF, but others do not

Correct answer: C

Rationale: The correct answer is C. The passage aims to provide an overview of cystic fibrosis (CF) and how it is inherited. It explains that CF is passed down through families due to a defective gene, detailing how this gene affects the body and who is most commonly affected by the disease. Choices A, B, and D are incorrect because the passage does not solely focus on describing the causes of CF, explaining how it is passed down through families, or reviewing why some Americans have CF while others do not. Instead, it provides a broader perspective on CF and its inheritance.

4. 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.

5. What is the writer’s primary purpose in writing this essay?

• A. To inform the reader about the dangers of high blood pressure
• B. To inform the reader how high blood pressure leads to a higher risk of heart attack
• C. To inform the reader how the cardiovascular system regulates blood pressure
• D. To persuade the reader that controlling one’s blood pressure is important

Correct answer: C

Rationale: The primary purpose of the essay is to inform the reader about how the cardiovascular system regulates blood pressure. The essay provides detailed explanations about the components of the cardiovascular system that regulate blood pressure, such as baroreceptors, chemoreceptors, and the kidneys. Choices A and B are incorrect because the essay does not focus on discussing the dangers of high blood pressure or its correlation with a higher risk of heart attack. Choice D is incorrect as the essay does not aim to persuade the reader to control their blood pressure but rather to educate them on the regulatory mechanisms of the cardiovascular system.
