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. Sleeping apparently helps with everything EXCEPT ___________.
- A. Fatigue
- B. Memory
- C. Learning
- D. Appetite
Correct answer: D
Rationale: Based on the provided extract, sleeping helps with fatigue, memory, and learning. The passage mentions how a nap can refresh the brain, improve the ability to learn and remember, and enhance memory. However, the extract does not mention anything about sleeping helping with appetite. Therefore, the correct answer is D. Choices A, B, and C are supported by the content of the passage, emphasizing the positive effects of sleep on fatigue, memory, and learning.
3. Which rainforest plant has more than one use?
- A. The Buruti plant
- B. The Banana tree
- C. The Cinnamon tree
- D. The Coconut tree
Correct answer: A
Rationale: The correct answer is the Buruti plant. The passage mentions that Amazonian Indians use the fruit and stem of the Buruti plant for various purposes, such as a drink, making bread, and building houses. The other choices, Banana tree, Cinnamon tree, and Coconut tree, are not specifically mentioned as having multiple uses in the passage. While the passage does mention that bananas and coconuts are available as food in the rainforest, it does not specify multiple uses for these plants as it does for the Buruti plant.
4. What conclusion can be drawn from the passage on bicycles?
- A. Bicycles have been evolving for centuries.
- B. Bicycles have evolved significantly over time.
- C. Bicycles have remained unchanged since their invention.
- D. Bicycles are no longer a popular means of transportation.
Correct answer: B
Rationale: The correct conclusion that can be drawn from the passage is that bicycles have evolved significantly over time. The passage discusses the evolution of bicycles from their early wooden, pedal-less designs to the modern safety bicycle with equal-sized wheels and chain-driven pedals. Each inventor mentioned in the passage contributed to significant improvements in bicycle design, making them more efficient and popular for transportation and recreation. Choice A is incorrect because the passage does not mention bicycles evolving continuously for centuries, but rather highlights specific innovations over time. Choice C is incorrect as the passage clearly describes the various improvements and changes made to bicycles since their invention. Choice D is also incorrect as the passage emphasizes the continued popularity and usefulness of bicycles for transportation all over the world.
5. Which might be a good title for this passage about Barefoot Running?
- 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' captures the main discussion in the passage.
