"How many cities are in America?"
Translation:Quot urbes in America sunt?
Not when you're using "in" I think. Not sure why you can't use the locative and drop the "in" though. It is consistent throughout the course for America, perhaps because it's not a Latin word?
Yeah I imagined it would be "Quot urbes Americae sunt? based on how "Roma" was inflected to "Romae" in other examples.
