What is the relationship between mutations and evolution?

GELO #6 – Question 2  Susie works for a lab company that develops many different pharmaceutical products. Her research division has stumbled across a new drug that they believe cures male pattern baldness. Before they can start selling the drug, they must demonstrate to the U.S. Food and Drug Administration that the drug is effective.  The company puts Susie in charge of this research project.   Susie randomly selects two groups of men to participate in the study: Group A and Group B.     Group A is administered the drug in pill form once a day for six months. Group B is given a pill that contains only inert ingredients once a day for six months.   All of the men will have the number of hairs per square inch of scalp measured in the clinic once per week.   Identify the experimental group in Susie’s study (Group A or Group B).
