On a set, (R) and (S) are both transitive relations. Which statement is always true?

Answer and explanation

Correct answer: (R\cap S) is transitive

Step 1: If ((a,b)) and ((b,c)) are in (R\cap S), then they are in both (R) and (S). Step 2: Since both (R) and (S) are transitive, ((a,c)) belongs to both, hence to (R\cap S). Step 3: The intersection of two transitive relations is transitive, but the union is not always transitive.
