Statement:
Please do not use lift while going down- an instruction on the top floor of a five-stores building.
Assumptions:
I. While going down the lift is unable to carry any load.
II. Provision of lift is a matter of facility and not of right.
Answer: D
Correct answer: If neither I nor II is implicit
The notice asks people to walk down; it does not say why. Assumption I supplies a mechanical reason - that the lift cannot carry load downward - which is not a property of lifts and is nowhere suggested. Assumption II states a general principle about facilities and rights, which is a justification the notice might invoke if challenged but does not rest on. The request stands as a request.
