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. What is the meaning of the word consensus as it is used in the last paragraph about Barefoot Running?

• A. Investigation.
• B. Purpose.
• C. Trepidation.
• D. Unanimity.

Correct answer: D

Rationale: "Consensus" refers to a general agreement or unanimity among individuals, particularly regarding the safety and effectiveness of barefoot running. The passage discusses differing opinions on this subject, indicating that there is not a unanimous agreement. Thus, choice D accurately captures the meaning of "consensus" within the context of the discussion.

3. What is the meaning of the word 'abstain' as used in the last paragraph?

• A. Dishonor
• B. Go without
• C. Connect to
• D. Liberate

Correct answer: B

Rationale: In the context of the passage, 'abstain' means to refrain from or go without. The passage discusses the challenges of treating individuals with both eating disorders and substance abuse issues. It mentions that while treatment for addiction involves abstinence, it is not possible to completely abstain from food. This highlights the meaning of 'abstain' as 'go without' in this context. The other choices are incorrect: 'Dishonor' does not relate to abstain, 'Connect to' is not synonymous with abstain, and 'Liberate' does not align with the context of the passage.

4. What is the overall tone of the essay?

• A. Apathetic
• B. Fascinated
• C. Discouraged
• D. Hopeful

Correct answer: C

Rationale: The overall tone of the essay is discouraged, as it conveys concern over the United States’ lower ranking in life expectancy and highlights various health issues contributing to this situation. The language used suggests frustration and disappointment regarding the country's health statistics, supporting option C as the correct answer.

5. What is the meaning of the word 'emitting' as it is used in the second paragraph?

• A. Repelling
• B. Releasing
• C. Closing
• D. Charging

Correct answer: B

Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.
