Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer : Statement : “Apply nets on windows to prevent the entrance of mosquitoes in the house.” Assumptions : I. The entering of mosquitoes from entrances other than windows is desirable. II. Nets are not available to apply on doors.

The correct answer is: C. Either I or II is implicit.

The statement “Apply nets on windows to prevent the entrance of mosquitoes in the house” does not explicitly state whether or not mosquitoes can enter the house through other entrances, such as doors. Therefore, assumption I is not necessarily implicit. Additionally, the statement does not explicitly state whether or not nets are available to apply on doors. Therefore, assumption II is also not necessarily implicit.

However, the statement does imply that mosquitoes can enter the house through windows, and that applying nets to windows will prevent this. Therefore, either assumption I or assumption II must be true in order for the statement to be true.
