Yes, a higher number of days with heavy rainfall in 1990 is certainly possible and would, in fact, be the simplest solution. But it's not the only possibility.

The key to this question is to realize that each category represents a range of rainfall amounts. For example, we know that in 1990 there were fewer days with moderate rainfall than in 1910. But moderate means 1-2 inches. Even though the number of moderate days was higher in 1910, we don't know whether the total rainfall during those moderate days were closer to 1 inch or closer to 2 inches.

Perhaps most of the moderate days in 1990 were closer to 2 inches and most of the moderate days in 1910 were closer to 1 inch. In that case, it would certainly be possible for the total rainfall on moderate days in 1990 to be HIGHER than the total rainfall on moderate days in 1910, even though the number of moderate days was higher in 1910.

Similarly, the number of heavy days in 1910 could have been higher, but the total rainfall during those "heavy" days may have been barely higher than 2 inches on average. On the other hand, 1990 might have seen fewer heavy days, but the total rainfall during each of those heavy days could have been massive. Thus, the total rainfall in 1990 could have easily been higher even if the number of days within each category was lower.

So while it is certainly possible that there were more heavy days in 1990, this does not HAVE to be true.

I hope that helps!

I applied the elimination process with the help of mathematical representation and left with A as others are not possible
