What the answer to the Greenlight Test Prep question? I get iii as an answer, but not i or ii, so I did something wrong...

Hi Brent,
I solved the question as follows https://greprepclub.com/forum/if-m-19-is-an-even-integer-which-of-the-following-must-tru-1846.html

Property Even/Odd is an integer and even. This means that its final value is even. As for positive or negative , it may or may not be so we cant be sure.

Is there any specific ordering of x,y,z that we have to follow for this question? I think we can assume values for the variables in any order necessary for reaching a conclusion. Please correct me if I am wrong.

Good question. Since there's no text suggesting the ordering of the integers, x, y and z can be arranged in any order.

Cheers,
Brent
