Answer 2

If I understand correctly, the sentence you provided is incomplete, and two words are missing. Based on the context you've provided ("not ask" and "not know"), the missing words could be:

"If I (do not ask) Michael, I (do not know) what to do."

This means that the speaker is uncertain about what to do, but they don't want to ask Michael for advice or information.
