alleryEquality of sets requires containment in:
ABoth durations
BBoth directions

Answer & Solution
Correct answer: B. Both directions
1. One set sitting inside the other is not enough.
2. The containment has to hold each way.
3. If every element of A is in B and every element of B is in A, the sets are equal.
4. So the answer is both directions.
