1. What does 'invasive' mean?

• A. Harmless
• B. Entering into a body part
• C. Mildly irritating
• D. Non-penetrative

Correct answer: B

Rationale: The correct answer is 'B: Entering into a body part.' 'Invasive' refers to something that invades or penetrates into a body part. Choice A, 'Harmless,' is incorrect as invasive implies a negative impact. Choice C, 'Mildly irritating,' is incorrect as invasive implies a more serious intrusion. Choice D, 'Non-penetrative,' is incorrect as invasive specifically denotes penetration or entry.

2. A caterpillar starts moving at a rate of 14 in/hr. After 15 minutes, it is moving at a rate of 20 in/hr. What is the caterpillar’s rate of acceleration?

• A. 6 in/hr²
• B. 12 in/hr²
• C. 24 in/hr²
• D. 280 in/hr²

Correct answer: C

Rationale: Acceleration is the change in velocity over time. The change in velocity for the caterpillar is 20 in/hr - 14 in/hr = 6 in/hr. Since this change occurred over 15 minutes (or 0.25 hours), the acceleration can be calculated as (6 in/hr) / (0.25 hr) = 24 in/hr². Therefore, the caterpillar's rate of acceleration is 24 in/hr², which corresponds to choice C. Choice A, 6 in/hr², is incorrect as it does not account for the time factor and the correct calculation. Choice B, 12 in/hr², is incorrect as it doubles the correct acceleration value. Choice D, 280 in/hr², is significantly higher than the correct value, indicating a calculation error.

3. How many gallons are in 16 quarts?

• A. 1 gallon
• B. 8 gallons
• C. 4 gallons
• D. 4.5 gallons

Correct answer: C

Rationale: To convert quarts to gallons, remember that 1 gallon equals 4 quarts. Therefore, 16 quarts ÷ 4 quarts/gallon = 4 gallons. The correct answer is 4 gallons because each gallon contains 4 quarts. Choice A (1 gallon) is incorrect because 1 gallon is equal to 4 quarts, not 16 quarts. Choice B (8 gallons) is incorrect as it miscalculates the conversion. Choice D (4.5 gallons) is incorrect because it doesn't align with the conversion rate of 4 quarts per gallon.

4. The rain will CEASE at sundown.

• A. Decrease
• B. Begin
• C. Stop
• D. Increase

Correct answer: C

Rationale: The word 'cease' means to stop or come to an end. In the given sentence, it is implied that the rain will stop at sundown, not decrease, begin, or increase. Therefore, the correct option is 'Stop.' 'Decrease' means to become smaller or less, which doesn't fit the context. 'Begin' means to start, which is the opposite of what is stated. 'Increase' means to become or make greater in amount, which is also contrary to the statement.

5. 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.
