Answer 1

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

**A plane ascends to 15,000 feet and then descends 15,000 feet. How many feet above the ground is the plane?**

In this case, the ascent and descent of equal magnitude (15,000 feet) result in a net change of 0 feet, meaning the plane is at ground level after the operations.
