Statement: "Apply nets on windows to prevent the entrance of mosquitoes in the house."
Assumptions:
1. The entering of mosquitoes from entrances other than windows is desirable.
2. Nets are not available to apply on doors
Answer: D
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.
