Answer:
The correct answer is option 3).En 2013, veías a tu padrino más.
Step-by-step explanation:
Examples containing verbs in the imperfect past are sentences number 3 and number 4.
The difference is that in the case of sentence 3 it is an irregular verb and in sentence 4 it is regular.
The imperfect past is used to show an action that took place continuously in the past, this means that it did not happen only once, but it happened more than once, but it does not happen today.
The verb in the example is the verb VER and here is its conjugation for the rest of the people:
Yo veía
Tú veías
Él/Ella/Usted veía
Vosotros/as Veíais
Ellos/Ellas/Ustedes Veían
