In Patton City, days are categorized as having heavy rainfall (more than two inches),

If the statements above are true, then it is also possible that in Patton City
A. the number of days with heavy rainfall was lower in 1990 than in 1910
definitely possible. Consider in 1990 one day about 1000000000 inches fell. (just kidding, but u get the point)
B. the number of days with some rainfall, but no more than two inches, was the same
in 1990 as in 1910 can't be true because we know moderate and light says were fewer in 1990 than in 1910
C. the number of days with some rainfall, but no more than two inches, was higher in
1990 than in 1910 same problem as in B
D. the total number of inches of rain that fell on days with moderate rainfall in 1990
was more than twice what it had been in 1910 not mathematically possible. We can only get twice the amount of rainfall if the number of moderate days were the same and all the moderate days in 1990 have 2 inches of rain and all the moderate rain days have 1 inch of rain in 1910
E. the average amount of rainfall per month was lower in 1990 than in 1910
not possible (unless there were more months in 1990 )since we are told total in 1990 was hight
really tuff one

I am still confused about option D.
As you said that one day it can rain 1000000000 so option A) is the answer. Likewise why can we assume that there were days in 1990 with moderate rainfall where it rained longer and hence total no. of rainfall is more.
if i assume correctly the size of the rainfall (given in inches) is the diameter of rain drops . so say 99 days in 1990 and 100 days in 1910:
in 1990 total rainfall =99 * 2(approx)*24(hours)
in 1910 total rainfall = 100*1 *11 hours
so 1990 it is more than twice..
please explain as to why above cannot be a possiblility
