So basically, your French teacher is having you rewrite the sentence, but with the addition of « ne...pas » surrounding the verb. For example, the fourth one would be « Non, je ne mange pas... » and then finish the sentence. You just have to remember conjugations (je, tu, il, elle, nous, vous, ils, elles). « ne pas » is like the English word “not,” as in: “I did not eat lunch.” In French, that would be « Je ne mange pas le déjeuner. »
