II. The sky is clear.
III. The temperature is not high.

Options

A. I only
B. II only
C. III only
D. I and III only

Answer

B

Explanation

This is a problem involving deductive arguments. Assume that the initial statements are true. Then test each choice. I is not necessarily true. For example, even though it is true that when it is raining, there are clouds in the sky, you cannot conclude from the fact that there are clouds in the sky that it is raining. III makes the same error. II, however, is inferable. It.s like reasoning as follows: When there are no clouds in the sky, it is not raining. It is raining, therefore, there are clouds in the sky.
