I can only answer 4 because i don’t know the story i’m sorry but 4 would be you can’t get it
Well, it depends on all on the sources. Web sites such as .org can be a reliable source. Some things that are usually reported, have an evidence and a claim to support what the article, and it should have a publisher and date at the bottom of the page. some common things to look for are headlines, a picture of proof, publisher, and the source^_^
I wanna say .Gov. Because it is like the official stuff... you know? Sometimes the .Org's lie and .Com's are not always trustworthy.
