I learnt in school today that in reporting questions we always use the same change of tenses as in reported statements. But is is 100% always the rule? I can think of one example when it feels wrong and I wonder if my feelings don't deceive me.
For question "what do you do?" is reported speech "he asked what she did" valid? It seems strange.. If I was in real life situation I would instinctively say "asked what she was doing" because it seems more appropriate for the meaning of "what do you do" question.
