Answer:
I think it's the 3rd one because it doesn't give a statement/opinion that can be answered/explained further. Instead, it states the fact that the average American eats more then three times the recommended amount of sugar.
Assuming all subjects have the same/equal credits, A is equivalent to 4, C is 2.
So, (4+4+2) / 3
n = (4+4+2) / 3
n = 10 / 3
n = 3.333333
n = 3.33
Hope this helps. :)
