Nice idea for a quiz, but Philadelphia, Phoenix and Fort Lauderdale all need correcting, and you should allow "New York" and "New York City" for the answers that only allow NYC at the moment.
Agree, tinsletown is LA not "hollywood". Hollywood is not a city or at least it is not a juristiction widely enough recognized to merit a nickname. As other commenters have said, please fix misspellings like for Philadelphia and accept New York city instead of just NYC
