You've posted two paragraphs with errors in them and two that have supposedly been corrected.

What directions have you been given? What are you supposed to do with these?
When using parentheses, if you have a parenthetical idea within a parenthetical idea, you would use brackets inside of parentheses.
They want me to correct the paragraphs with parentheses or brackets inside of parentheses, but I don't understand it that well and I been going over it over a weeks or so.
