I don't get how this makes any sense. The top paragraph says, 'they each order either margherita, pepperoni... ham and pineapple or vegetable pizza.' This clearly indicates that vegetable pizza is chosen, else why would it be included in this statement?
Then, the answer indicates that 'we know that no one ordered a vegetable pizza.' Doesn't this directly contradict the previous point, even IF 2 ordered margherita, 2 ordered ham and pineapple and 1 pepperoni? I just don't understand it, it seems like a DIRECT contradiction to me. Anyone have any other take on it that I'm missing out on ?
thanks for the help
