Answer to Question 1

A no-treatment control group is simply left alone and literally does not receive any treatment. A placebo control group, on the other hand, receives an artificial treatment that looks like a real treatment but actually has no effect. Thus, the participants in a placebo control group think that they are receiving a treatment when they really are not.

Answer to Question 2

True
