Question 307083
If m+n is an odd number, then one of the numbers must be even and the other must be odd.  Now, if you take the product of this even and odd number, you ALWAYS get an even number!  The square of this even number will always be an even number, so the correct answer is E.  All of the other choices will always give you an odd number.
