    ***** NOT A TEACHER *****


    This is how I understand it.

    (1) Let's say (for example) that Tom has 2 sisters and 2 brothers. Let's say that they all contribute money to buy ONE car that they will share.

    If that is the case, you would ask Tom: Does your sisters and brothers' car go fast? (one apostrophe. The one car belongs to one group of people)

    (2) Usually, however, you would say something like this:

    My sisters' and brothers' carS are very fast. (Two apostrophes)

    That is: My sisters' cars are very fast, and my brothers' cars are very fast.


    The rule also applies if you have only one sister and one brother:

    My sister and brother's car is fast. (The two persons own one car together.)

    My sister's and brother's carS are fast. (Each person owns a car.)
