1. 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.

2. What is stated in the passage about the Olympic Games?

• A. The Olympic Games are held every four years.
• B. The Olympic Games are often postponed.
• C. The Olympic Games are held only in leap years.
• D. The Olympic Games only involve certain countries.

Correct answer: A

Rationale: The correct answer is A: 'The Olympic Games are held every four years,' as stated in the passage. The extract explicitly mentions that the Summer Olympic Games are held every four years. Choice B is incorrect as there is no mention of the Olympic Games being often postponed in the passage. Choice C is incorrect because although the Olympic Games occur during leap years, they are not exclusively held only in leap years. Choice D is incorrect as there is no indication in the passage that the Olympic Games only involve certain countries.

3. What conclusion can a reader draw from this passage?

• A. It is advisable to choose unsaturated fats over saturated fats.
• B. Saturated fats are more calorically dense than unsaturated fats.
• C. Trans fats are more calorically dense than saturated fats.
• D. Unsaturated fats are mostly found in animal products.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage is that it is advisable to choose unsaturated fats over saturated fats. The passage emphasizes the health benefits of unsaturated fats, such as lowering cholesterol levels and reducing the risk of heart disease. It also mentions that saturated fats, although not as healthy as unsaturated fats, should still be consumed sparingly. Trans fats are highlighted as the least healthy fats, increasing the risk of heart disease. Choice B is incorrect because the passage does not explicitly compare the caloric density of saturated and unsaturated fats. Choice C is incorrect as the passage does not discuss the caloric density of trans fats in comparison to saturated fats. Choice D is incorrect as the passage states that unsaturated fats are found in sources like olive oil, walnut oil, and avocado oil, not mostly in animal products.

4. 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.

5. The author seems to?

• A. Oppose drinking alcohol
• B. Favor a strict diet
• C. Oppose regulation of personal habits
• D. Advocate moderation and balance

Correct answer: D

Rationale: The passage does not explicitly state the author's stance on alcohol consumption or dieting. However, the description of playing Bridge emphasizes qualities like time, effort, and attention to become proficient. This suggests that the author likely favors moderation and balance in one's approach to activities, rather than extremes like excessive drinking or strict dieting. Choice A is incorrect because the author does not express opposition to drinking alcohol. Choice B is incorrect as there is no indication of the author favoring a strict diet. Choice C is incorrect as there is no direct mention of opposing regulation of personal habits in the passage.
