Explanation
(While studying the efficacy of a new medicine, two Exercises of persons with the same attributes are chosen and only one set is administered the medicine. The progress of that set of persons in comparison of the other set who were not administered the medicine is studied in order to determine its effect. The latter group is known as the 'control group'. The word 'control' has been used in this question in this sense.) The opposite of control is the group experimented on.
