1. E. Dr. Brown supports his conclusion, namely that people in the community are taking better care of their health, on the evidence that they are coming to his office more often.
2. B. The conclusion refers to the community as a whole, whereas the evidence is only drawn from Dr. Brown’s personal experience.
