Hey there!

Let's look at all our options.

We're looking for a reason why not.  If we look at the first one, we notice that continuing medical advances contribute to the cause mentioned in the problem, therefore we can rule that out.

The second one looks like our oddball, because it isn't entirely true. Slower population growth is anything but what's happening nowadays, and the population is actually increasing. It has nothing to do with communicable disease spreading. Therefore, B is your answer.

But let's see our other options. Improved living conditions and better preventative treatment are ways that decrease the spread of diseases, so they're ruled out.

Hope this helps!
