Statement: The airlines have requested all their bona fide passengers to check the status of flight operations before leaving their homes as heavy fog is causing immense problems to normal flight operations.
Assumptions:
I. The majority of the air passengers may check the flight status before starting their journey to the airport.
II. The Government may take serious objection to the notice issued by the airline company.
III. Majority of the passengers may cancel their tickets and postpone their journey till the situation becomes normal.
Only I is implicit
To make the request meaningful assumption I must be a valid assumption. Hence, assumption I is implicit. In case of II, government is out of the picture. Hence, assumption II is not implicit. Assumption III is also invalid as the case may be only of delay, not of cancellation of flight.
