Statement: Everybody loves reading adventure stories.
Assumptions:
1. Adventure stories are the only reading material.
2. Nobody loves reading any other material.
3. All are literate.
Answer: A
The statement mentions that adventure stories are liked by everybody. This does not mean that there is no other reading material or nobody loves reading any other material. So, neither I nor II is implicit. Besides, 'everybody' in the statement stands for 'all literate people' and not for 'all people'. So, III is also not implicit.
