I Can't stand these! I kind of but don't really understand the answer

W+ + Z ---> No RXN
X+ + W ---> No RXN
Y+ + X ---> X+ + Y
Y+ + Z ---> Z+ + Y

Orderr in terms of increasing ability as a reducing agent.

Z is worse than W
W is worse than X
X is better than Y
Z is better than Y

Therefore, Z is worse than X.
X is best.
Y is worst because it's worse than Z which is pretty ••••••.
Z is one above Y and W is between Z and X so the final answer;

Y, Z, W, X
