What implies that something may not happen? a. if i had a few dollars i'd buy us some ice cream sandwiches b. i don't have enough experience so i can't be a lifeguard this summer c. since we're out of eggs i'll just have oatmeal instead

A, because it says if, which is implying that it is still possible.

but it is sometime nessary to hit key points or subjects   but is sometimes to much reveiw if there was a way to slim down the redone work it would improve for every body.
