1. What is the best summary of the passage?

• A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
• B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
• C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
• D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.

2. The passage explicitly states?

• A. That the highest card within the 'trump' suit always wins the trick.
• B. That there is a pile of leftover cards that is placed in the middle of the game table.
• C. If a player cannot follow suit, they lose their turn to the next player.
• D. The Ace card is always the lowest card.

Correct answer: A

Rationale: The correct answer is A: 'That the highest card within the 'trump' suit always wins the trick.' The passage explicitly mentions that in the game of Bridge, if a player plays a card from the trump suit, it always wins the trick. This detail is clearly stated in the text, making it the correct choice. Choice B is incorrect as there is no mention of a pile of leftover cards in the passage. Choice C is incorrect as the passage does not state that a player loses their turn if they cannot follow suit; instead, they play any card. Choice D is incorrect as the passage states that the ace is high, not low.

3. What does the author of the passage on the Electoral College seem to suggest?

• A. The Electoral College should be abolished.
• B. The Electoral College works as intended.
• C. The Electoral College needs reform.
• D. The Electoral College confuses voters.

Correct answer: B

Rationale: The correct answer is B. The author of the passage suggests that the Electoral College works as intended. Despite acknowledging its confusing nature and the possibility of results differing from the popular vote, the author highlights that the founding fathers had a purpose behind its design. Therefore, the Electoral College is viewed as functioning as intended. Choice A is incorrect because the author does not advocate for abolishing the Electoral College. Choice C is incorrect as there is no explicit mention of the need for reform. Choice D is incorrect as the author does not focus on the confusion caused to voters but rather on the system's original purpose.

4. Which statement is not listed as a detail within the passage?

• A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
• B. The signal has a characteristic record called the electrocardiogram.
• C. The 'wave of excitation' starts at the SA node.
• D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.

Correct answer: A

Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.

5. In this passage, which of the following is not mentioned as a role of HGH in the human body?

• A. Regulating the metabolism.
• B. Stimulating the immune system.
• C. Regulating leptin, an appetite-controlling hormone.
• D. Facilitating calcium retention.

Correct answer: C

Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.
