If z is an integer, is z even?

(1) z/2 is even.
(2) 3z is even.

Hi everyone,

This may be a very easy question but I need help logically breaking down. Any help would be very much appreciated. This is from a CAT from the MGMAT course.

The answer is D.

The the question is phrased the only parameter is that Z is an integer, so no fractions/decimals. When you are testing (1) and (2) are you only testing with an even number because it states "is z even"?

thanks!
