A is the reason; B is the evidence
提示One says why in general; the other points to something that happened.
为什么A reason answers 'why do you think so?'; evidence answers 'how do you know?'. An argument needs both, in that order: each reason in turn, with a fact or example attached. The school in sentence B is an invented example.
