la noire can you still get all the clues if you answer wrong

Answer 1

It depends on the question. Some questions don't give you any clues anyway. Some questions give you clues that you can get elsewhere. Some clues might not be found anywhere else. You should still be able to complete the case even if you do miss a clue, but your rating at the end of the game will suffer for it.
