I am confused about why we had to define swimming costume.
If we found out why you asked us to define swimming costume, would it help us guess the answer?
and two more environmental questions?
Is he wet? (if you want definition: wetter than a person is normally)
Is he hot? (if you want definition: hotter than a person is normally)
and another two questions about the rock:
Is the fact that it is a rock he is lying on relevant? (i.e. rather than grass or sand or something)
Is the type of rock possibly relevant (e.g. whether it is granite or sandstone etc)
and about the man's health:
Are all the man's internal organs present?
Are all the man's internal organs (apart from those used in movement) working?
