Translation:Which person is the judge shouting at, the Hungarian or the English person?
I am not that far in the course to give an educated opinion, but i can give an uneducated one:
A labdát a bíró dobja embernek.
The judge throws a ball to a person.
(A szavakat) a bíró kiabálja embernek.
The judge shouts (words) at a person.
I would expect the person, that is shouted at, to be in dative.
Would surprise me if anything of that is near the truth.
