An advertisement for a diet aid claims that the aid has proven effective in 90% of patients. It presents testimony of users who explain how much weight they lost by taking the aid. During the commercial you hear from six different users who claim to have had great success losing weight. If the makers of the diet aid had scientific evidence of its effectiveness, what would the commercial most likely include

a. Information comparing the results of users to those of a control group
b. A list of active ingredients and their safety record
c. Information about users' starting and ending weights
d. More personal testimony, but from actual doctors instead of users
it would not be C or D in my opinion. B would not be proof that it actually works but would be a nice addition. xD
So i think A would be your best bet.

Which of the following questions can be answered scientifically?
