Directions : In each of the following questions a statement is given, followed by three conclusions. Give answer : Statement : The national air carrier has decided to start a weekly air service from town A to town B. Assumptions : I. There will be enough passengers to make the operation economically viable. II. Other carriers may not start such service. III. The people staying around these towns can afford the cost of air travel.

The correct answer is: Only I is implicit.

The statement says that the national air carrier has decided to start a weekly air service from town A to town B. This implies that the national air carrier believes that there will be enough passengers to make the operation economically viable. However, the statement does not say anything about whether other carriers may start such service or whether the people staying around these towns can afford the cost of air travel. Therefore, only assumption I is implicit.

Here is a brief explanation of each option:

• Option A: Only I is implicit. This is the correct answer.
• Option B: Only I and II are implicit. This is not the correct answer. Assumption II is not implicit because the statement does not say anything about whether other carriers may start such service.
• Option C: Only II and III are implicit. This is not the correct answer. Assumption III is not implicit because the statement does not say anything about whether the people staying around these towns can afford the cost of air travel.
• Option D: All are implicit. This is not the correct answer. Only assumption I is implicit.
• Option E: None of these. This is not the correct answer. Assumption I is implicit.
