Answer:
The question is incomplete, you are asked to draw a production possibles frontier between safety and range and explain how it works.
I drew a bounded out curve, where you can maximize safety but at the same time you minimize range, or the opposite. If you are located in a point of the curve, lets say point 0, and wish to gain range and move to point 1, you will lose safety. If you want to increase safety and move to point 2, you will lose range.
