Alexia is writing a research paper about cell phones. Her thesis is that cell phone use while driving leads to major health hazards.
She has decided to use the Internet for part of her research study. After doing a search for airbags, she comes across an article on the
homepage for the Department of Motor Vehicles with statistics regarding accidents due to cell phone use. The article is credited to Jim
March, an EMT from Albuquerque and clearly states that people who use cell phones while they drive increase their risk of causing an
accident. She bookmarks the site and continues to research. Later, she comes across a website called CarStuff. com. There is a
commentary that is written by an anonymous source that says cell phone use and driving are perfectly safe.
What is one way for Alexia to decide which source is more credible?
