x^3 is even when x is even

1. 2x + 2 is even for both odd and even -INSUFF
2. 3x +1 is even for odd, so x is odd SUFF

Ans: B

The answer is B.

1.) Insuff

2x+2: the '2x' term will be even regardless if x is is even or odd.

2.) Suff

Whether the term '3x' will be even or odd relies on x. Because we are told that the equation is even, we know x must be odd (Odd + Odd= even)
