Demonstrative adjectives

There are three demonstrative adjectives in Spanish. I will be using the masculine versions for now:

1. Este meaning this - something that's close to you.

2. Ese meaning that - something's that still fairly close to you but not that far away.

3. Aquel meaning that - Aquel and ese are quite similar, but aquel means it's pretty far away.

How the demonstrative adjective changes based on the subject:

Masculine singular: Este, Ese, Aquel

Feminine singular: Esta, Esa, Aquella

Masculine plural: Estos, Esos, Aquellos

Feminine plural: Estas, Esas, Aquellas

Example sentences:

Este profesor habla mucho = This teacher talks a lot

Esa camisa es bonita = That shirt (you’re wearing) is pretty

Aquellos estudiantes no comprenden = Those students (over there) don’t understand

Esta chica está lista = This girl is ready

Esos libros son estúpidos = Those books (you just picked up) are stupid

Me gusta aquella casa = I like that house (on the other side of the street)

the answer is c. estudió

explanation:

to translate: last year a group from my school went to cuba and studied the history of the island. you would use preterite form because it was one time and they use fue in the sentence.
