$Q \text{ or } \left\{0, 2, 4, 6, 8, 10, 12\right\}$
$x \in M$ or $x \in Q$ means that the elements of the given set are either in M or in Q. This is actually the definition of the union of the sets M and Q. Thus, the given set is equivalent to: $M \cup Q = \left\{0, 2, 4, 6, 8, 10, 12\right\} = Q$
