Statement: "Please keep the doors of the emergency ward closed while leaving the ward, to keep the room germ-free."
Assumptions:
Assumption I: Leaving the doors of the emergency ward open will cause germs to enter.
This is implicit because the purpose of the sign is to instruct people to keep the doors closed to prevent germs from entering. The underlying assumption is that leaving the doors open would allow germs to enter the ward.
Assumption II: People are likely to pay attention to this notice.
This is also implicit because the hospital expects people to follow the instruction on the signboard. If they didn’t assume people would pay attention, they wouldn't bother putting up the sign.
