Explanation:
The Simple Preterite indicates an enunciated action that is considered finished. It applies to actions completed in the past that are not necessarily related to the factual status of the present situation.
It is used in Spanish to express: actions that take place at a certain moment in the past in a timely manner or a new action that occurs in the past and that interrupts a course of action that was already in progress and that is expressed in the past tense.
