A control is the standard by which experimental observations are evaluated. In many clinical trials, one group of patients will be given an experimental drug or treatment, and the control group is given either a standard treatment for the illness or a placebo. If you have worked with clinical trials/observations, you will understand what the 'control' or 'control group' is. If you have not, discuss what you do know. In most cases, an interviewer will know if you already have clinical trial experience and will know where to guide you with a question like this.
