Thanks.

I mean if we study all the caves in the world by viewing national geographic channel on television set or by physically visiting all the caves personally which is rather difficult, Do all the caves have same entry & exit points?
I mean we enter a cave, there can be single exit, multiple exits.
Or
there could be caves where there are multiple entries with multiple exits or a single exit. Some examples similar to caves could be theatres, auditoriums, sports stadiums etc.
