Presently, the Manufacturers of Nutritional Supplements Are Not Required to Obtain

Presently, the manufacturers of nutritional supplements are not required to obtain approval from the U.S. Food and Drug Administration (FDA) to verify the claims of the effectiveness of the health products they sell. Suppose a company wants to market a new herbal supplement which it claims improves memory. A scientifically informed citizen would hope that someday the FDA would insist that before it approves such a product, research on the effectiveness of the supplement would:

A) be quasi-experimental.
B) compare it to people already taking a supplement.
C) compare it to a placebo treatment.
D) be conducted on young people who are most likely to use it.
