Помогите пожалуйста! Нужно предложения 1) He is playing the piano now? 2) He was coming tasty dinner yesterday? поставить во: Общий, специальный, разделительный, альтернативный вопрос. Прошу помогите! ЗАВТРА В ШКОЛУ!(

1) Is he playing the piano now? What is he playing now? He is playing the piano now, isn`t he? Is he playing the piano or guitar now? 2) He was doing (coming???) tasty dinner yesterday. Was he doing tasty dinner yesterday? What was he doing yesterday? He was doing tasty dinner yesterday, wasn`t he? Was he doing tasty dinner or supper yesterday?  Здесь во втором с глаголом мне не ясно; не может быть coming, смысла нет)))
