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. Why did Macmillan add iron rims to the tires of his bicycle?

• A. Increase the weight of the bicycle.
• B. Enhance the durability of the tires.
• C. Reduce the bumpiness of the ride.
• D. Decrease the level of fatigue during the ride.

Correct answer: B

Rationale: Macmillan added iron rims to his bicycle tires to enhance their durability and make them last longer. This innovation aimed to prevent the tires from getting worn down quickly. Adding weight to the bicycle (Choice A) was not the purpose of adding iron rims. While adding iron rims could potentially reduce the bumpiness of the ride (Choice C) by providing more stability, the main objective was to improve tire longevity. Similarly, reducing the level of fatigue during the ride (Choice D) was not the primary reason for adding iron rims.

3. Which of the following is not listed as a detail in the passage about Yoga?

• A. Improved circulation.
• B. Strengthening of core muscles.
• C. Stress reduction.
• D. Fortification of immune system.

Correct answer: D

Rationale: The passage outlines several benefits of yoga, such as improved circulation, strengthened core muscles, and reduced stress. However, it does not mention the fortification of the immune system, which is not discussed in the context of the benefits of yoga. This makes D the correct answer, as it is the only option not supported by the passage.

4. What is the main idea of this passage?

• A. The water cycle consists of precipitation, evaporation, and condensation
• B. Water cycle components include only evaporation and condensation
• C. The water cycle includes precipitation, runoff, evaporation, and condensation
• D. The water cycle happens in the atmosphere only

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, which are precipitation (rain, snow, sleet, or hail), runoff, evaporation, and condensation. Choice B is incorrect because the water cycle involves more than just evaporation and condensation. Choice C is incorrect as it includes an additional element, runoff, not mentioned as a primary component of the water cycle in the passage. Choice D is incorrect as the water cycle involves processes both in the atmosphere and on the ground.

5. What can the reader conclude from this passage about ponds and lakes?

• A. They are examples of groundwater reservoirs.
• B. They are part of the evaporation process.
• C. They are formed by runoff.
• D. They are formed by condensation.

Correct answer: A

Rationale: The correct answer is A: 'They are examples of groundwater reservoirs.' The passage mentions that runoff collects in groundwater reservoirs, among other places. Ponds and lakes are typically reservoirs of groundwater, as stated in the passage. Choice B is incorrect because ponds and lakes are not directly mentioned as part of the evaporation process. Choice C is incorrect as ponds and lakes are not stated to be formed by runoff. Choice D is incorrect as ponds and lakes are not formed by condensation.
