proof or disproof

1) If R and R' are partial orders on A, then R U R' is a partial order on A

2) If R and R' are equivalence relations on A, then R U R' is an equivalence relation on A

For the first question, I think it is true but not sure how to prove it. Since R and R' are partial orders on A, then that means every element in A is reflexive, asymmetric and transitive with each other in A.

For the second question, I can't think of anything yet.

Please help me out. Thanks
