Answer 1

Resposta:

A) Did you work a lot yesterday? / I didn't work a lot yesterday.

B) Were the kids playing football? / The kids weren't playing football

C) Have you already studied math? / I haven't already

Explicação: Nas perguntas eu troquei o I pelo YOU.

- Em pergunta e negativa no passado, você utiliza o DID. A não ser que tenha o was/were.

- A letra C) está no present perfect, então não utiliza o DO.
