Statement: “Do not lean out of the moving train”, a warning in the railway compartment.
Assumptions:
I. Such warning will have some effect.
II. Leaving out of a moving train is dangerous.
III. It is the duty of railway authorities to take care of passengers’ safety.
All are implicit
Assumption I and II are implicit because the warning against leaning out suggests one to be careful are against the dangers involved. No doubts that ensuring the passengers safety is the responsibility of railway authorities and hence III is also a valid assumption.
