Statement: Mostly people who stop smoking gain weight.
Assumptions:
I. If one stops smoking one will gain weight.
II. If one does not stop smoking, one will not gain weight.
Read the statement and assumptions and decide which of the assumptions is implicit in the statement.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → If neither I nor II is implicit
An assumption is implicit only if the person making the statement must take it for granted. The statement speaks only of “mostly” people who stop smoking, that is, most, not all of them.
Assumption I (If one stops smoking one will gain weight) is not implicit: it claims that everyone who stops smoking gains weight, while the statement allows that some do not.
Assumption II (If one does not stop smoking, one will not gain weight) is not implicit: the statement says nothing about people who go on smoking; they may or may not gain weight.
