General Knowledge— Italy

It would be a fun quiz but for the fact that you want such exact answers. Five of them I knew but was marked wrong - the river, the university, the gallery, the mafia and the pasta dish. In the case of the pasta, I preceded it with the word spaghetti and the rest I didn't expect to have to add words such as "the" (la) or words given in the question, like University or River. Could you please see your way to accepting some alternative ways of expressing the answers?
