When do you say going down questions? When I was a student, I learned English grammar from Japanese at school. 　My teachers said, "In these cases, the questions that can answer with yes or no, you should say going up the ending of them. On the contrary, the questions starting with interrogative, you should say going down the ending of them. However, I hear you say going up even with interrogative. What is correct? When do you say going down questions? どんな質問のときに語尾を下げて言いますか？
