Please help with these questions I don't understand 

Suppose a Iinit test case terminates with a faiture reporting this error message
Expected: Set2 "(1, 2)" but wwas: Set4 "(2, 1)"
What does the message mean?
O The methods in your implementation of Set4 are not stonng the elements of the set in
the right order.
O The test didn't crash, so the methods of Set4 work There is an error in the Set4
constructor.
O You can't compare a Set2 to a Set4: they are different dynamic types.
O One of the kernel methods you have implemented is used by the implementation of
equals() in SetSecondary and is not working correctly.
