Nothing about the availability of pencils is mentioned in the statement. So, I is not implicit. Also, in the statement, the staff has been instructed to provide pencils with each invigilator. This means that despite being instructed, all the candidates might not bring the pencil. So, II is also not implicit.
6. Statement: Most people who stop smoking gain weight.
Assumptions:
If one stops smoking, one will gain weight.
If one does not stop smoking, one will not gain weight.
