This quiz is asking for the least number of states you would have to travel through in order to get from one state to another. For example, if the hint was "Massachusetts to Maine", the answer would be 2 because you pass through New Hampshire and Maine. Also, if the hint were "Massachusetts to Maine (via New York)", you would have to travel from Massachusetts to Maine while also passing through New York. Therefore, the answer would be 4, because you would have to pass through New York, Vermont, New Hampshire, and Maine. You cannot pass through a state more than once.
