Recall that binary relations are merely sets of pairs of elements of some set. Therefore if R and Q are binary relations on a same set A, their union R ∪ Q as sets of pairs is also a binary relation on A. Is it true that if R and Q are antisymmetric then R ∪ Q is also antisymmetric? Prove that it is or give a counterexample.
