Answer 1

The situation that describes opposite quantities that when combined would equal 0 is:

A diver was 30 feet below the surface and swam upward 30 feet. What is the change of elevation?

In this case, the diver's movement of 30 feet upward (positive) and the original position of 30 feet below the surface (negative) combine to result in a change of elevation of 0 feet, as they would return to the surface level.

Other options involve changes or distances that result in non-zero values, so they do not represent opposite quantities that sum to 0.
