Answer 1

Respuesta:

1. They didn't stop the dangerous man.

2. My cousin didn't explain the problem.

3. He didn't study in the library.

4. It didn't rain last night.

Explicación:

Past simple (Negative)

Subject + didn't + verb + complements

I didn't study yesterday.

My dog didn't play with me.

Cuando hay una negativa, el didn't (did + not) ya lleva el pasado, por eso el verbo se escribe en infinitivo.

Espero que te sirva :)
