I've never been to Venice and, given that many people have told me that they've found it to be smelly, expensive and disappointing, it's not high on my list of places to visit.
I've never really been impressed with Rome. There are other Italian cities which I'd prefer to visit.
I love Paris. It's vibrant, fascinating, packed with culture, reasonably priced and with the most efficient waiters in the world.

Perhaps the competition was set in conjunction with the 'i' newspaper. Their sub-editors have been guilty of allowing the 'either/or' error (with more than two alternatives offered) on several occasions recently.
