If m is an integer, is m odd?

1. m/2 is NOT an even integer
2. m-3 is an even interger.




Answer is B.

2. Suff

With 1, since it says "NOT an even integer", does that mean that is either an odd integer or not an integer at all?

The explanation in the book says m could be odd integer 3 or an even integer 10 to satisfy this condition. Just want to make sure I am assuming correctly. THANKS!

Yes, that's exactly right.

All Statement 1) tells you is that m is not divisible by 4; m could still be even or odd.
