Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer : Statement : Use PVC pipes which have 10 years longer life to any other. Assumptions : I. People prefer only those pipes which are durable. II.Other pipes are not durable.

The correct answer is: Only assumption I is implicit.

The statement “Use PVC pipes which have 10 years longer life to any other” does not provide any information about whether people prefer only those pipes which are durable. It is possible that people prefer PVC pipes for other reasons, such as their cost or ease of installation. However, the statement does suggest that PVC pipes are durable, since it states that they have a longer life than other types of pipes. Therefore, assumption I is implicit.

Assumption II is not implicit. The statement does not say anything about whether other pipes are durable or not. It is possible that other types of pipes are just as durable as PVC pipes, or even more durable. Therefore, assumption II is not implicit.

Here is a more detailed explanation of each option:

• Option A: Only assumption I is implicit. This is the correct answer. As explained above, assumption I is implicit, but assumption II is not.
• Option B: Only assumption II is implicit. This is not the correct answer. Assumption II is not implicit, as explained above.
• Option C: Either I or II is implicit. This is not the correct answer. Assumption I is implicit, but assumption II is not.
• Option D: Neither I nor II is implicit. This is not the correct answer. Assumption I is implicit, but assumption II is not.
• Option E: Both I and II are implicit. This is not the correct answer. Assumption I is implicit, but assumption II is not.
