Following is an array of questions to test your reasoning ability in different situations. Answer each of them according to the question asked in each of them respectively:

Which alternative applies to the following Statement and Assumption? Statement: Go by Aeroplane to reach Delhi from Chennai quickly. Assumptions:
I. Chennai and Delhi are connected by Air service.
II. There is no other means to commute from Chennai to Delhi.
III. The Air distance between Delhi and Chennai is less.

The correct option is Only I and III are implicit.

Let us analyze the statement and each assumption step-by-step:

Statement: "Go by Aeroplane to reach Delhi from Chennai quickly."

Assumption I: Chennai and Delhi are connected by Air service.
This assumption is implicit because advising someone to go by aeroplane to reach Delhi from Chennai logically presupposes that air transport services operate between these two cities. Without air connectivity, the advice would be meaningless.

Assumption II: There is no other means to commute from Chennai to Delhi.
This assumption is not implicit. The statement mentions taking an aeroplane to reach "quickly", which implies that air travel is a faster mode, not that it is the only mode of transportation available between Chennai and Delhi.

Assumption III: The Air distance between Delhi and Chennai is less.
This assumption is implicit in the context of choosing air travel for speed and quickness across spatial routes connecting distant points efficiently. Therefore, taking an aeroplane implies that the air route provides a direct or minimal travel distance for a quick journey.

Hence, assumptions I and III are implicit in the statement, making Only I and III are implicit. the correct choice.
