1. What does 'km' stand for in the metric system?

• A. kilometer
• B. kilomole
• C. kilobyte
• D. knot

Correct answer: A

Rationale: In the metric system, 'km' stands for kilometer, which is a unit of length equal to 1,000 meters. This choice is correct as 'kilometer' is the standard unit for measuring long distances. Choice B, 'kilomole,' is incorrect as it is a unit in chemistry representing a quantity of substance. Choice C, 'kilobyte,' is incorrect as it is a unit of digital information storage, not a unit of measurement. Choice D, 'knot,' is incorrect as it is a unit of speed used in navigation and aeronautics, not a unit of length in the metric system.

2. Which blood vessels carry deoxygenated blood from the body back to the right atrium of the heart?

• A. Arteries
• B. Veins
• C. Capillaries
• D. Venules

Correct answer: B

Rationale: Veins are the blood vessels that carry deoxygenated blood from the body back to the heart. Arteries transport oxygenated blood away from the heart. Capillaries are the smallest blood vessels where gas exchange occurs between blood and tissues. Venules are small veins that connect capillaries to larger veins, but they do not directly carry deoxygenated blood back to the heart.

3. How do you spell the past participle of the verb 'lie' (to recline)?

• A. lied
• B. lain
• C. lay
• D. lying

Correct answer: B

Rationale: The correct spelling of the past participle of the verb 'lie' (to recline) is 'lain.' 'Lied' is the past tense form of the verb, not the past participle. 'Lay' is the simple past form. 'Lying' is the present participle form. Therefore, the correct answer is 'lain,' representing the past participle form of the verb 'lie.'

4. Which number is larger, 0.5 or 1/3?

• A. 0.5
• B. 1/3
• C. They are equal
• D. Cannot be determined

Correct answer: A

Rationale: To compare 0.5 and 1/3, we can convert 0.5 to a fraction, which is 1/2. When comparing 1/2 and 1/3, we find that 1/2 is greater than 1/3. Therefore, 0.5 is larger than 1/3. Choice B is incorrect as 1/3 is smaller. Choice C is incorrect as the numbers are not equal. Choice D is incorrect as a clear comparison can be made.

5. Using the same reasoning as that in the passage, an automobile with eighteen wheels does what to the following hypothesis: 'All automobiles have only four wheels'?

• A. It proves the hypothesis.
• B. It raises the hypothesis's probability.
• C. It disproves the hypothesis.
• D. It decreases the hypothesis's probability.

Correct answer: D

Rationale: An automobile with eighteen wheels contradicts the hypothesis that 'All automobiles have only four wheels.' This contradiction reduces the probability that the hypothesis is true. The hypothesis is not proven by the presence of an eighteen-wheel automobile, nor does it raise the probability of the hypothesis being true. Instead, it directly challenges the hypothesis, leading to a decrease in its probability of being correct.
