Question

la semana pasada la maestra nos (enseñaba / enseñó) del pretérito y el imperfecto.
enseñaba
enseñó

Explanation:

The sentence "La semana pasada la maestra nos (enseñaba / enseñó) del pretérito y el imperfecto" requires choosing the correct verb form. "Enseñaba" is the imperfect tense, used for ongoing or habitual actions in the past, while "enseñó" is the preterite, used for completed actions. Since the context is about what the teacher was doing (teaching about tenses) last week, the imperfect "enseñaba" is appropriate as it describes an ongoing action during that past time.

Answer:

enseñaba
