Answer 2

Answer:

Not until you pay the money will you get the camera back.

Explanation:  

When a sentence begins with ‘not until’ it is initiated with an assertive phrase which has to be mandatorily be followed by a conditional phrase. Here the condition is ‘you pay the money’ so this phrase will follow ‘not until’. After asserting the condition the causal effect is stated which is ‘you will not get the camera back’.  

Thus the final sentence stands as: Not until you pay the money will you get the camera back.
