You just have to think of random examples to answer these questions.
For the first one you're supposed to persuade someone to do something. It doesn't even have to be a good argument, you just have to put reasons to prove your argument.
For the second one you have to prove that you don't believe someone. Just imagine what you don't believe in and say what you don't believe that someone is saying and why.
