Sharon reads two different articles about avocados. The first article, in a weight-loss magazine, claims that avocados are unhealthy because they are high in fat. The second article, in an annual publication from a doctors
group, claims that the fat in avocados is a type that is good for the heart.
To assess these claims, which question might Sharon ask?
O Which source do avocados come from?
O Where are avocados sold?
Is the source an authority on the subject?
O How much do avocados cost?
