You hear: alejandro llevó un suéter marrón. You choose: preterite present preterite present preterite present preterite present preterite present preterite present preterite present preterite present preterite

The correct answer is "preterite".

In fact, the name of this verb tense is pretérito perfecto simple. It is used for action which started and finished in the past, hence is an absolut past tense.

It is not always the case when learning Spanish, but there is an equivalent tense in English for the preterite that is the past simple.
