About 10 days ago, I learned on this forum that there are regional differences in use of exposure by windows and cross-ventilation. Some people live in houses with windows on all four sides, some live (in England especially) in houses with only front and rear doors & windows, and some live in apartments with just windows on a balcony. Despite all that background, I think that in a generic sentence (without an actual house involved, or plane for that matter) all 4 answers would be acceptable.
