"Many universities are in Rome."
Translation:Multae universitates Romae sunt.
Is there a rule when to use "Romae" as a locative or "in Roma" as a ablative construction?
In this case 'Multae universitates in Roma sunt' was marked incorrect ...
I believe in this course I've only ever encountered "Romae" (contrasting with "in Italia"), so I simply thought you couldn't have "in Roma".
In the meantime, I read in another discussion that the locative is used for cities, but that you must apply the ablative for countries and states.
Thus: Romae, Bostoniae, ...
in Italia, in California, ...
