It means he does not write to solve problems, he writes about the problem itself.
Fake news often happens when someone is not satisfied with something and makes a lie for example, when one of our presidents was elected tones of false allegations popped up because some people wanted our president out.
For me, to make fiction realistic is to have normal people in the story and have something strange come out of the blue. For example, there are researcher that study UFOs, so maybe have a conflict that has something to do with UFOs. Hope that helps!!!
