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 best title for the passage on bicycles?

• A. Bicycles Are Better.
• B. Cycle Your Way to Fitness.
• C. A Ride through the History of Bicycles.
• D. The Popularity of Bicycles.

Correct answer: C

Rationale: The correct answer is C: 'A Ride through the History of Bicycles.' This title best captures the passage's focus on the historical development and evolution of the bicycle from its invention to its modern form. Choice A, 'Bicycles Are Better,' is too general and doesn't encompass the historical aspect discussed in the passage. Choice B, 'Cycle Your Way to Fitness,' focuses solely on the fitness aspect of bicycles, ignoring the broader historical context. Choice D, 'The Popularity of Bicycles,' touches on one aspect but does not encompass the comprehensive historical journey presented in the passage.

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. FRAX takes into account all of the following factors EXCEPT ___________.

• A. Lifestyle choices
• B. Exposure to toxins
• C. Genetic heritage
• D. Exposure to sunlight

Correct answer: B

Rationale: FRAX, a tool used to assess fracture risk, considers various factors like lifestyle choices, genetic heritage, and exposure to sunlight. However, exposure to toxins is not mentioned in the provided extract as a factor considered by FRAX. Therefore, the correct answer is B. Exposure to toxins is unrelated to fracture risk assessment as per the information provided. Lifestyle choices, genetic heritage, and exposure to sunlight are all factors that FRAX takes into consideration to determine the risk of experiencing a fracture within the next decade.

5. What is the meaning of the word satiety as used in the last paragraph about The Sleep Workout?

• A. A state of tiredness.
• B. A state of being satisfied.
• C. A state of being overloaded.
• D. A state of confusion.

Correct answer: B

Rationale: Satiety refers to a state of being satisfied, particularly in terms of appetite. In the context of the excerpt provided, it explains that individuals who lack adequate sleep may experience lowered levels of leptin, a hormone that controls appetite. As a result, even after meeting their caloric needs, they may still crave carbohydrates, indicating a lack of satisfaction or satiety. This can lead to obesity and disrupt healthy eating habits. Therefore, choice B, 'A state of being satisfied,' is the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the meaning of satiety in the context of appetite regulation and sleep's impact on food cravings.
