You're accountable for the answer to the question that you knew you should ask, even if you chose not to ask it.
It may be that you were the only person smart, good, or experienced enough to ask it. So, if no one else asks, then you must do it.
Sometimes the key to having influence is asking difficult questions. The answers may be hard, but you ask anyway.
Unasked questions usually find a way to answer themselves sooner or later.
