    Answer:

    2 ways

    Step-by-step explanation:

    The best way to do this is to fix the position of the stranger and then arrange the two identical twins

    The number of ways of knowing where the stranger will seat is 1! ways = 1 way

    The number of ways of arranging the two identical twins is 2! ways = 2*1 = 2 ways

    The number of sitting arrangements = 1 * 2 = 2 ways
