Would you please tell me how we give an answer in a short form to questions like 'did there use to be many dinosaurs on the earth'?
---'No, there weren't'? or 'No, there didn't use to be'?
Did there use to be many dinosaurs on the earth?
Firstly, please tell me if I understand this question correctly - if I ask this question, it implies that I know there aren't many dinosaurs on the earth now, but I want to know if there were many dinosaurs before. Is that right?
Secondly, since there aren't any dinosaurs now, so this question is kind of weird. Am I right?
