Re question 6... Neither answer is correct all of the time. Balanced inserts may use 3 conductor cable, but uses two separate cables to send and return. The only case where the answer is both is on an unbalanced (single TRS) insert.

Question 6 isnt necessarily correct. The true correct answer is that the insert cable must carry send and return signals. The 3 wires thing isnt true. Some consoles use a mono 1/4 in send and a mono 1/4 return.
