Your professor gave you an assignment to write a research papaer on the pros and cons of cell phones and driving. The Professor told you that she wants you to use 3 books, 3 articles, and 1 website.
After your visit to the Library you feel really confused. So many sources to choose from and they all looked good!
But really how good were they? One book, about the history of the telephone was written in 1991. The articles were about which cell phone plan to buy. The only website you could find was full of flashing gimmicks advertising cool phones in hot colors.
How do you solve this problem? How do you decide which source to use?
