Answer to Question 1

There are various ways to answer this question. We could examine the changing
composition of the stratosphere over this interval, and see what things might have changed.
That meaning could give clues as to the source of the decrease in ozone. We could conclude
that whatever causes the ozone hole must be increasing in strength. At the very least, we can
conclude that something is changing because the hole area is changing.

Answer to Question 2

This does occur.
