In Patton City, days are categorized as having heavy rainfall (more than two inches), moderate rainfall (more than
one inch, but no more than two inches), light rainfall (at least a trace, but no more than one inch), or no rainfall.
In 1990, there were fewer days with light rainfall than in 1910 and fewer with moderate rainfall, yet total rainfall
for the year was 20 percent higher in 1990 than in 1910. If the statements above are true, then it is also
possible that in Patton City
The main point-
(number of rainy days in 1910 > number of rainy days in 1900)
doesn't mean
(rainfall in 1910 > rainfall in 1900)
pretty obvious as the amount of rain in a rainy day coupled with number of rainy days will determine that.
A. the number of days with heavy rainfall was lower in 1990 than in 1910
There is possibility.
B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910
False. it is greater in 1910 than in 1900.
C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910
False. it is greater in 1910 than in 1900.
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
1 inch < moderate (1910) < 2 inches
1 inch < moderate (1900) < 2 inches
moderate (1900) > 2 *moderate (1910)
Impossible. simple arithmetic.
E. the average amount of rainfall per month was lower in 1990 than in 1910
the rainfall in 1900 is 20% higher than in 1910.
So the average amount in 1900 has to be higher than in 1910.
Wrong.
A is the most suitable one. Correct.

Here is very good explanation https://www.gmatclub.com/forum/veritas-prep-resource-links-no-longer-available-399979.html#/2013/0 ... -the-gmat/
B , C and E can be eliminated easily as they contradict the facts in stem. Choice D can't be true , If we pay attention to the stem. Moderate rainfall is > 1 and <= 2 . So 2 times of 1.00001 will be 2.00002 , which is more than 2 inch. Hence , by the information in stem this choice can't be true and is incorrect.
Option A can be true assuming certain conditions.

I would request Gmat ninja and veritas prep to help explain the question and OA, I am thinking that the number of days with heavy rainfall should be more in 1990 than in 1990, but OA is the exact opposite
