    Subset making a true statement

    {All states west of the Rocky Mountains} {All states west of the
    Atlantic Ocean}


    I have make a true statement out of the question above, so I have to figure out if the twostatements are a


    Proper Subset
    is a subset of
    is not a subset of
    proper subset and is a subset of

    The first answer I selected for the question was proper subset and is
    a subset of, but obviously the answer was wrong when I done the problem as practice. I think the answer may be is not a subset of, but I am not sure.
    Thanks for any help on this.

    If I remember the geography right, every (US) state west of the Rocky Mountains is also west of the Atlantic ocean, but not vice versa. So it seems to me that your initial answer was right.

    Just interested: how did you do this problem "as practice"?
