**Question #14**

If *n* is an integer, is *n* – 1 even?

(1) *n* – 2 is odd

(2)* n* + 1 is even

**Explanation**

If *n* – 2 is odd, then we know that *n* itself must be odd. Not sure about that? Make up some numbers and test it out. So if *n* is odd, then *n* – 1 must be even. Statement (1) is sufficient.

Statement (2) tells us that *n* + 1 is even. That means that *n* is odd, which means that *n* – 1 is also even. Statement (2) is also sufficient! The correct answer is (D).
