an ad for a weight - loss supplement claims that people who use the supplement will lose 20 pounds in one month. this is based on a study conducted by the company. a statement in the print explains that the claims have not been evaluated by the food and drug administration (fda). which concern does this advertising raise? \\bigcirc if the supplement has not been evaluated by the fda, it might not be safe. \\bigcirc claims that are tested by many companies might still be biased. \\bigcirc claims that show the dramatic results of the supplement cannot produce those results. \\bigcirc claims that are tested only by the company selling the supplement are probably false.
Answer
Brief Explanations:
The ad's claim is based on a study by the company selling the supplement. When a claim is tested only by the seller, there's a conflict of interest as the company has an incentive to show positive results, so such claims are likely false. The other options: A is about FDA evaluation (the ad says claims not evaluated, but the concern here is about self - testing), B is about multiple companies (not the case here), C is about showing results (the issue is who tested, not showing).
Answer:
D. Claims that are tested only by the company selling the supplement are probably false.
