Circle the letter of the best definition for a squeeze?

Answer 1

a. A condition that causes pain and discomfort when the pressure outside an air space of your body is less than the pressure inside an air space.

b. A condition that causes pain an discomfort when the pressure inside an air space of your body is less than the pressure outside an air space.

b would be the right answer.

Addition

Technically all are incorrect. While "B" is the typical answer for an Open Water class, the pressures are virtually the same. This is because an air space will collapse until the pressures equalize. It is actually a volume question that is affected by the external pressure.
