Question

Mi abuelo __________ setenta y dos años ayer.a. cumplió c. cumple

Answer 1

The answer is A. Cumplió.

Cumplió is the conjugated past form of the verb cumplir in the form of el/ella/usted. We know that this sentence is referring to the past, because it uses "ayer" which means yesterday. Cumplir means to turn, and is used when talking about birthdays.

The correct phrase is
Mi abuelo cumplió setenta y dos años ayer
My grandmother turned seventy-two yesterday.

I hope this helps!

Answer 2

A. The answer is cumplió.
Cumple is referring to someone else. Va a cumplir is referring to someone who will be turning a certain age. Cumplía is someone who turned a certain age.
