1.  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.
A. Only assumption I is implicit.
B. Only assumption II is implicit.
C. Either I or II is implicit.
D. Neither I nor II is implicit.
E. Both I and Ii are implicit.

Answer: Option D

Explanation:

The statement talks of a way to keep mosquitoes away. This means that entry of mosquitoes in the house is not desirable. So, I is not implicit . Besides, the statement advises using nets on windows. So, nothing about the use of nets on doors, can be deduced. Thus, II is also not implicit.
