I mean this thread: Who was the first rock act to apply Jamaican music?
It’s about the interrogative. After posting that thread, I soon felt that it’s wrong and it should have been “What”. I must’ve though that a “rock act” is a person, but in fact it’s rather a concept, an abstract thing. You know, my native language is German, and the rules for interrogatives are quite different because of the genders, so I’m still not sure. It’s bugging me, so please help me out.
