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 does the word 'composed' mean in the passage on the Water Cycle?

• A. To consist of.
• B. To create.
• C. To separate.
• D. To destroy.

Correct answer: A

Rationale: In the context of the Water Cycle, 'composed' means 'to consist of' parts. For instance, water is composed of hydrogen and oxygen atoms. Therefore, the correct meaning of 'composed' in this context is to consist of various components. Choice B, 'To create,' is incorrect as 'composed' refers to the makeup of something rather than the act of making or creating. Choices C and D, 'To separate' and 'To destroy,' are also incorrect as they do not align with the meaning of 'composed' in the passage.

3. What is the meaning of the word composed in the first paragraph?

• A. To consist of
• B. To break apart
• C. To mix with other elements
• D. To heat up

Correct answer: A

Rationale: The word 'composed' means to be made up of or to consist of something. In the provided extract, it describes how a single drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is 'To consist of.' Choice B, 'To break apart,' is incorrect as it is the opposite of 'composed.' Choice C, 'To mix with other elements,' is incorrect as 'composed' refers to being made up of specific components, not mixed with others. Choice D, 'To heat up,' is unrelated to the meaning of 'composed' in this context.

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

• A. “Everyone Should Run Barefoot”
• B. “How to Prevent Running Injuries”
• C. “Modern Road Surfaces Versus Barefoot Running”
• D. “The Debate over Barefoot Running”

Correct answer: D

Rationale: The title "The Debate over Barefoot Running" encapsulates the central theme of the passage, which explores both the advantages and disadvantages of barefoot running. It effectively summarizes the discussions around differing opinions and the lack of consensus on this topic. Other titles do not accurately reflect the primary focus of the essay, making D the most suitable choice.

5. Why did the author write this passage?

• A. To explain insomnia and propose some solutions for the condition.
• B. To encourage people to avoid sleep.
• C. To criticize people who have sleep problems.
• D. To promote the use of sleep medication.

Correct answer: A

Rationale: The correct answer is A. The author wrote the passage to explain insomnia and suggest ways to deal with it. The passage provides information about insomnia, its impact on daily life, and offers solutions like sleep hygiene and non-pharmacological therapies. Choices B, C, and D are incorrect as the passage does not encourage avoiding sleep, criticize people with sleep problems, or promote the use of sleep medication. Instead, it focuses on understanding and addressing insomnia.
