How do you know what information is fact and what information is fiction in the Internet? What do you do to determine what information you can trust?

Well you should look in any books that deal with that information. So you can go to the library and if you are going to read then you will find just enough information. Not everything in the computer is correct. And that way i will read both information from the computer and out the book and if it matches then you will know whats fiction and whats the facts.
