Below are people that you can choose to "interview". Your task is determine whether wearing a new type of mask is effective at protecting against air-borne viruses. By clicking on a person, you will be given a response about whether that person has gotten sick by the end of the week. Each person you ask will have a cost of 10 points, which is deducted from your budget above. Your first two interviews with each type of person are free.
