However, I was thinking of a situation where X and Y are both equal to 4..

If that is the case, then (X+Y) (X-Y) is equal to 0 and is not divisible by 8?

I'm under the assumption that X and Y are different numbers. If they were the same number, they would both be X.

I initially got E, but after looking over the problem again, C makes perfect sense. When you check out statement 1 by itself, it doesn't say a whole lot. But when you combine statement 2, it makes sense.

For example:

X=5, Y=3

X+Y = 8

X-Y = 1

No dice

X=12, Y=4

X+Y = 16

X-Y = 8

So, you need X and Y to be even integers for the equation to work, that's why Statement 1 is important and that's why the OA is C.
