Question

You pick up a brochure at the grocery store. You cannot find any information about the people who created it. This information is _____. reliable or unreliable

Answer 1

When you pick up a brochure at the grocery store, and you cannot find any information about the people who created it, then the source is unreliable!

Answer 2

Unreliable.  This is because you need to know who the work is written by to help determine if it is reliable or not.  Also, if you are on a Wikia or a blog, you may not be able to find an author.  This is because people come and go writing and changing things as they please.
