! i think all answers are likely!

The benefit of the space shuttle is that A. it's reusable. This means that after this shuttle has been used for one mission, it can be use for numerous other missions again, until it gets broken and cannot run anymore. B is incorrect because it cannot land - it is only there to observe. C is incorrect because more than one person can fit. D is incorrect because it doesn't orbit the Earth permanently - it returns at one point.

The air is going to come out because of the low pressure.
