Alison is writing a research paper about marathons. Her thesis is that running a marathon is good for a healthy heart. She has decided
to use the Internet for part of her research study. After doing a search for marathons, she comes across an article on the homepage for
the American Medical Association about the benefits of regular exercise and marathon training. The article is credited to Dr. Elizabeth
Jones, a cardiologist from Milwaukee in residence in at St. Luke's Medical Center. She bookmarks the site and continues to research,
Later, she comes across a website called Runner's Daily Pace. There is a commentary that is written by a person named Randy Tuttle
that says regular running wears out the heart and leads directly to heart attacks.
What is one way for Alison to decide which source is more credible?
A. The Runner's Daily Pace article is more credible because it is a commentary and not an article.
B. The American Medical Association is more credible because it agrees with her thesis.
C. The Runner's Daily Pace site has a piece that challenges her thesis, so it is more credible.
D. The information from the American Medical Association comes from doctors and physicians, so it is more
credible.
