I don't know if you need to write the answers on a negative way(words like no, never, etc) but on the first question give you details to how answer a questions in a correct way.
Ex. le compras una camisa a tu novio? No, no le compro una camisa. (negative way) you need to read carefully all the sentences to see the correct way to answer.
Hope this helps, good luck.
До завтра should be the answer
