How does my lung capacity compare to a trained athlete

Well a traines athlete has build their lung capacity to withstand the amount of pressure put on it, but for someone who is not a trained athlete their ling capacity is not as great and can not with stand as much pressure.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
