During a mid-life crisis, people began to question: a. their career choices b. their education c. their existence

Well I can speak from experience when I went to my midlife crisis I was basically focusing on my career at which point there was confusing for me it wasn't clear as to what I want to do.

The answer would most likely be A.

I’m going to guess these are the choices: a) recreational skiing developed in the mid-19th century b) it was originally invented as a way of getting from place to place in snowy regions c) downhill skiing is currently the only common form of the sport d) it mostly evolved from snowshoeing- if that’s the cases then the answer would be c) downhill skiing is currently the only common form of the sport
