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. Which statement would not be inferred by the reader in the passage about Super Foods?

• A. Instant oatmeal can be part of a healthful breakfast.
• B. Blueberries are an especially healthful food.
• C. Certain grains and dairy products are super foods.
• D. Super foods are more expensive than processed foods.

Correct answer: D

Rationale: The passage does not imply or provide information regarding the cost of superfoods compared to processed foods. Therefore, D is the correct answer, as it identifies a statement that cannot be inferred from the passage.

3. What is implied by this paragraph about food and drink?

• A. We should eat and drink in reasonable quantities.
• B. Alcohol should be banned.
• C. People should eat in large quantities.
• D. We need stronger laws to control drunk drivers.

Correct answer: A

Rationale: The paragraph emphasizes that while food and drink are necessary and desirable, their abuse can lead to serious physical and mental problems. It highlights the negative consequences of overeating and alcohol abuse, such as strain on the heart, diabetes, and other health issues. The text suggests the importance of moderation in consumption to prevent health problems. Choices B, C, and D are incorrect because the paragraph does not call for a ban on alcohol, promote eating in large quantities, or specifically discuss the need for stronger laws to control drunk drivers.

4. Why was the roadway of the Golden Gate Bridge so dangerous to build?

• A. It was located above a fast-moving river.
• B. It had to be perfectly balanced to avoid collapse.
• C. The materials used were very unstable.
• D. It was built during bad weather.

Correct answer: B

Rationale: The correct answer is B. The passage describes how the road had to be balanced during construction to avoid collapse into the bay. Choice A is incorrect as the Golden Gate Bridge crosses a strait, not a river. Choice C is incorrect as there is no mention of unstable materials. Choice D is incorrect as bad weather is not highlighted as a specific reason for the danger in building the roadway.

5. What conclusion can be drawn about the article?

• A. The author explains differences in eating methods.
• B. Eating habits vary across different cultures.
• C. Space travel has posed challenges for eating habits.
• D. Chopsticks are more suitable than forks for space travel.

Correct answer: A

Rationale: The correct answer is A. The passage discusses different eating methods in various cultures, focusing on their differences. The author describes the development of cutlery in European cultures, the use of chopsticks in China, and how space travel has influenced eating tools for astronauts. Choice B is incorrect because the passage emphasizes the differences rather than the similarities in eating habits across cultures. Choice C is partially supported by the passage as it mentions that space travel has created new challenges for consuming food, but it is not the main conclusion of the article. Choice D is not directly supported by the passage as it discusses the challenges of using chopsticks and forks in space rather than stating that chopsticks are superior to forks.
