Evaluating Scientific Explanations

Question 6 • Physical Science Sem 1 (2003310) BCPS 2026-27

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?

Answer
A
Which source do avocados come from?
B
Where are avocados sold?
C
Is the source an authority on the subject?
D
How much do avocados cost?

Explanation

The articles make conflicting claims about whether avocado fat is unhealthy or heart-healthy. Sharon should consider whether each source has relevant expertise and credibility on nutrition, so she can judge how reliable its claim is. “Is the source an authority on the subject?” is the useful question; where avocados come from, where they are sold, and their cost do not assess the claims.
