When balancing the half reaction in 14.11 O2 > OH-, how do you come to the conclusion that the reaction is occurring in a basic solution when not given that information?

Because the OH- is already present, you can assume this is a basic reaction. If this were in an acidic reaction, the OH- would interact with H+ to form water, and therefore you would not be able to have OH- present.
