Could someone please help me with this:
Poor weather in early 14th-century Europe created meager harvests, causing the result of mass starvation in some areas and the elimination of as many as 15 percent of the population.
A causing the result of mass starvation in some areas and the elimination as many as
B causing the result of mass starvation in some areas and eliminating as much as
C resulting in mass starvation in some areas and the elimination of as much as
D and resulted in mass starvation in some areas and the elimination of as many as
E causing mass starvation in some areas and the elimination of as many as
I chose D which is incorrect. One of the reasons listed is that population is uncountable and hence using as many as is incorrect. I know C, which is the correct answer makes sense but I am having problems with the "as many as" explanation given. Population is a countable noun..or isn't it
