Accepted Answer

A double-blind study is a type of study in which both the subjects and the researchers do not know whether the subjects are receiving the treatment or the placebo. This helps to reduce bias and increase the validity of the results.

The correct answer is E because advertising is regulated by advertising standards and it is illegal to include misleading nutrition information in advertisements.

Television programs may include information about nutrition, but they are not inherently promoting a product in the same way that an advertisement would be.

Question 16

Accepted Answer

Scientifically, the body has its own natural detoxification processes and adding supplements or other products claiming to "detoxify" the body can be dangerous or ineffective.

Question 19

Accepted Answer

Clinical trials require an experimental group receiving the treatment being tested and a control group not receiving the treatment, in order to compare the results. A and B are not necessarily required for all clinical trials, and D is not a requirement but rather a desired outcome. E may be necessary depending on the specific trial, but it is not a universal requirement.
