Question

todos los veranos ( visitábamos / visitamos ) a la república dominicana.

Explanation:

The sentence "Todos los veranos" (Every summer) indicates a repeated past action, which is expressed by the imperfect tense in Spanish. The verb "visitar" (to visit) in the imperfect tense for the first - person plural (nosotros) is "visitábamos". "Visitamos" is the preterite tense, used for completed actions, while the context here needs the imperfect to show a habitual action in the past.

Answer:

visitábamos
