Correctly conjugate. Based on the context, decide whether you would conjugate the verb in the preterite or imperfect.
Anoche yo
(comer) en un restaurante con mi familia.

Respuesta :

Answer: Anoche yo comi  en un restaurante con mi familia.

Explanation: El verbo se debe conjugar en preterito perfecto, ya que es una accion que comenzo en el pasado y ha finalizado.  

Mientras que el imperfecto se utiliza para describir personas, situaciones o cosas.

The verb must be conjugated in perfect preterite, since it is an action that began in the past and has ended.

While the imperfect is used to describe people, situations or things.
