Question

The ability to bounce back from extreme stress is called _____. pessimism perfectionism optimism resilience

Answer 1

The answer should be resilience

Answer 2

The correct answer is resilience.

Optimism is hope/dream based that the stress will get better. 
Pessimism is just seeing the sadness in everything, which would just result in the stress caving in on them. 
Perfectionism would be the outlying dumbo answer, as it correlates to nothing in this context.

Hope this helped!
