If yes WHY?? If not modify ResCust so as to put it in INF.

If not modify ResCust1 so as to put it in 2NF. Let us call ResCust2a and ResCust2b the two new relations, i.e. the two relations resulting out of this step (vii) {20 points} Is ResCust1 in 3NF? If yes WHY?? If not, modify ResCust1 so as to put it in 3NF.
