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

A. the number of days with heavy rainfall was lower in 1990 than in 1910

B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910

C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910

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

Traps you into thinking that the number of days with rainfall in a given year and the quantity of rainfall in a given year are equivalent quantities.

E. the average amount of rainfall per month was lower in 1990 than in 1910

The argument:
HR > 2
1 < MR < 2
0 < LR < 1
NR
# days LR of 1990 < # days LR of 1910
#days MR of 1990 < # days MR of 1910
Total # R of 1990 (#LR + #MR + #HR) > Total #R of 1910 (#LR + #MR + #HR)
(A) possible. suppose in 1990 there were only 5 days with heavy rainfall but rain was 100 inches a day and in 1910 there were 6 days but rain was only 3 inches a day. Thus total in 1990 can be greater than total in 1910
(B) impossible
(C) impossible
(D) (X) days of MR in 1990 < (Y) those in 1910
=> (X) x from 1 to 2 cannot double (Y) x (from 1 to 2)
(E) impossible because total rainfall in 1990 = 120% total in 1910

I think D is as possible as A.
suppose in 1910 we had days with 1 inch rainfalls
suppose in 1990 we had days with 1.99999 inch rainfalls
it can, just as in A, be true that the amount of rainfall in 1990 for moderate rainfall was greater than in 1910...

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

B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910

C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910

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

E. the average amount of rainfall per month was lower in 1990 than in 1910

Lets analyse each choice

A correct it says that there were fewer days with heavy rainfall in 1900 than 1910
Now if that is true we have 20% more rainfall in 1900 so there must have been more rainfall on these heavy rainfall days to exceed the rainfall of 1910.

B If this is true then the conclusion is false as there were fewer days with light rainfall in 1900 than 1910.

C No information is provided regarding this in the argument Out of scope

D It is a tempting choice but still does not tell us that the amount of rainfall was sufficient enough to exceed that of 1910

E If this is true the conclusion is wrong

The argument states that there are 4 kinds of days – Heavy rainfall (>2), Moderate rainfall (b/w 1 and 2), Light rainfall (<1), and
No rainfall

And then,

There were fewer rainfalls of light and moderate in 1990 than in 1910.

Total rainfall in higher in 1990 than in 1910.

We need to pick the answer that will be true based on the argument (Main point)

A. the number of days with heavy rainfall was lower in 1990 than in 1910

It may be possible because lets assume heavy rainfalls – in year 1910 were equal to 20 and in range of 2.1 to 2.2. So we have total rainfall caused due to heavy rainfall is equal to MAX value of 44

And

In year 1990 is equal to 15 in range of 15 to 20. So we have total rainfall caused due to heavy rainfall is equal to MIN value of 225.

So, let's keep this answer choice as a contender.

B. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910

Not possible as per the argument

C. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910

Not possible as per the argument

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.

Let's assume moderate rainfall that is b/w 1 and 2 range in 1910 was 10 with lower value of GE(1). Therefore, total number of inches of moderate rainfall is GE(1) * 10 = GE10

in 1990 is 9.9 with the maximum value of 2. Therefore, total number of inches of moderate rainfall is LE(2) * 9.99 = LE(19.9)

Clearly it is not double and it is not possible to get value that is more than twice the double

We can eliminate this answer choice

E. the average amount of rainfall per month was lower in 1990 than in 1910

If total is higher then average should be higher. So we can also eliminate this answer choice.
