1. What are the three steps of the 'wave of excitation'?

• A. The discharge from the SA node, the peak ECG, and the excitement of the ventricle.
• B. The excitement of the ventricle, the relaxing of the ventricle, and the systemic neural response.
• C. The contraction of the atrium, the relaxation of the atrium, and the contraction of the ventricle.
• D. The excitation of the atrium, the excitement of the ventricle, and the relaxing of the ventricle.

Correct answer: D

Rationale: The correct steps of the 'wave of excitation' are the excitation of the atrium, excitement of the ventricle, and relaxation of the ventricle. In the described process, the 'wave of excitation' starts with the discharge from the SA node, leading to the excitation of the atrium. Next, the peak ECG corresponds to the excitement of the ventricle, not its relaxation. Finally, the wave concludes with the relaxation of the ventricle, not its contraction. Therefore, choices A, B, and C are incorrect as they do not accurately describe the sequential steps of the 'wave of excitation' as presented in the extract.

2. A reader might infer from this passage that the organization ___________.

• A. succeeded in eradicating malaria
• B. has always been led by a medical doctor
• C. no longer studies communicable diseases
• D. changed its name to match its mission

Correct answer: D

Rationale: The passage never says whether or not the CDC succeeded in its original mission (choice A) or whether it continued to be led by doctors (choice B). Inferring either of those things would be a leap unsupported by the text. Choice C is countered by information in the final

3. What is implied by the author's mention of the Kayapo people in the passage on the Amazon Rainforest?

• A. The Kayapo people destroy the environment for farming.
• B. The Kayapo people farm in an environmentally friendly way.
• C. The Kayapo people contribute to deforestation.
• D. The Kayapo people hunt animals for survival.

Correct answer: B

Rationale: The mention of the Kayapo people in the passage highlights how they farm in an environmentally friendly manner. Instead of using chemicals, they enrich the soil by burning wood and plant banana trees, attracting wasps that feed on harmful insects. This sustainable farming practice showcases their efforts to coexist with the rainforest ecosystem without causing harm. The other choices are incorrect: A is refuted by the passage as the Kayapo people are described as farming in an environmentally friendly way, C is incorrect as the passage does not mention the Kayapo people contributing to deforestation, and D is not supported by the text as there is no mention of the Kayapo people hunting animals for survival.

4. What can the reader infer about the 'sweatiest students' referred to in the last sentence in the passage?

• A. These students are more physically active than others.
• B. These students have worked harder during class.
• C. These students do not necessarily perform better academically.
• D. These students excel in all sports activities.

Correct answer: B

Rationale: The correct answer is B. The reader can infer that the 'sweatiest students' have worked harder during class. This inference is supported by the context that students are graded based on the effort they make in the class, with some even receiving extra credit for being the sweatiest students in the room. Choice A is incorrect as there is no indication in the passage that the sweatiest students are more physically active than others; they are recognized for their effort, not necessarily for being the most active. Choice C is incorrect as the passage does not discuss the academic performance of the sweatiest students. Choice D is incorrect as there is no evidence to suggest that the sweatiest students excel in all sports activities; they are acknowledged for their effort rather than their overall sports performance.

5. 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.
