    Scientists are doing a study to find out if a particular type of asthma medicine will decrease the number attacks patients experience. In Group A, 20 participants are given an inhaler and directed to take one inhalation of medicine each day for 30 days. After the 30 days, they report how many attacks they’ve experienced. In Group B, 20 participants are given an inhaler and the same directions as the participants in Group A. However, in Group B the inhaler contains no medicine; the participants (unknowingly) inhale only plain air. After 30 days, Group B reports how many attacks they’ve experienced. Which term describes Group B? A. Control group B. Independent group C. Experimental group D. Dependent group
