Your parents surprise you with a $500 check. as a result, the u.s. gdp decreases because you have to pay taxes on this income. remains unchanged because it was counted when your parents earned it. decreases because you will spend it on useless goods. increases because this is unexpected income to you.

I believe that the $500 cheque from your parents has already been counted when it was earned and therefore would neither increase or decrease GDP. GDP is defined basically as  a bulk measure of production that is equal to the sum of all gross values of all units involved in production.
