    Are you allowed to take the contra positive of a rule, or not?

    For example, if the rule is:

    "if there is a rain storm, the hotel must provide umbrellas to its guests"

    are you allowed to say that:

    "if the hotel is not required to give an umbrella to its guests, it is not raining"

    Or do situations like that simply not arise in these question types?
