If (R={(1,2),(2,3),(1,3)}) and (S={(1,3),(3,4),(1,4)}), what type is (R\cup S)?

Answer and explanation

Correct answer: Not transitive

Step 1: (R\cup S) contains both ((2,3)) and ((3,4)). Step 2: Transitivity requires ((2,4)), but it is not in the union. Step 3: Chains from two different relations can create a new missing pair in the union.
