Those are both correct. Vitacco for Colombo, Corozzo for Gambino.
*****NOTE: But I just realized I made an error. I omited another Gambino. This original question was supposed to have 2 guys for each of three crews; 2 Colombo, 2 Genovese and 2 Gambino....Not 5 guys.
So please take note of that. I corrected the quiz accordingly, ok.
