Complete Question:
Rosie and Jackie are good friends. Jackie has always been there for Rosie, and Rosie really leaned on Jackie when she was going through a hard breakup. Jackie is also really funny, and she makes Rosie laugh. Since becoming friends, Rosie realized she rarely gets colds, and when she does, they don't last long. Unfortunately, Jackie just moved across town, so it takes Rosie 45 minutes to get to Jackie's house. But, Rosie doesn't seem to mind the drive because she and Jackie are such good friends. In fact, Rosie helped Jackie move to her new apartment.

Answer:
The response to the question is a discrete random variable.
Explanation:
By definition of a discrete random variable we infer that the response can only take certain known values but the response shall be completely random. As an example when we toss a fair coin the out comes are discrete as only either head or tail is possible and the outcome is random meaning we cannot predict the outcome before hand.
Similarly an continuous random variable takes any value in a set and there are infinitely many possible values it can take. For example if we choose any real number between 1 and 10. Since the answers are infinitely many in number and are completely random.
Now in our survey we can infer that the responses shall be either "yes I smoked last week" or "No i didn't smoke last week". Hence the variables are discrete and random.
