Statements of authority provide the strongest evidence in scientific discussions when they are based on statements that are, "consistent with findings from high-quality scientific research on the subject."
The statements which are based on findings from high-quality scientific research are accurate and so they provide the strongest evidence in scientific discussions.
The Scientific method of research is neutral, objective, rational, and as a result, is able to approve or disapprove the hypothesis. The research method includes the procedure to obtain data and evaluate the variables, and then it obtains analyzable data.
Hence, the statements based on high quality scientific research provide the strongest evidence.

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.
