Twenty sprint cyclists were randomly selected to be in a study designed to test the effectiveness of 12 weeks of creatine supplementation on performance. Ten cyclists received a creatine supplement for 3 months while the other ten received a powdered supplement with the same color and texture that has no physical effect for 3 months. The cyclists did not know which supplement they were taking but the researcher did.Which group was serving as the control group?
a. The cyclists who received a creatine supplement
b. The cyclists who received an inert powder supplement
