Which of the following is not a reason why communicable diseases, such as pneumonia, kill fewer people today than they did in the past? a. continuing medical advances b. slower population growth c. improved living conditions d. better preventive treatment

The answer would be B., as all the others are true and do help these diseases kill fewer people.

The answer would be B. If you look at what our comunities used  to be and what they are now, we actually have a lot more people than we used to. Now you can get shots to prevent and cure, and when things are cleaner than they used to be, there is less chance of catching them in the first place.
