I don’t quite understand the question is the whole question?
The preterite tense is a completed action in the past, and the imperfect is something that happened in the past but was ongoing.
- Te llamé dos veces ( I called you twice-completed action)
-Él vivió<span> allí por cinco años. (He lived there for five years- completed action)
</span>-<span>Yo </span>caminaba<span> cada día. ( I used to walk everyday. - was ongoing)
</span>Yo comía<span> frecuentemente McDonald's. ( I used to McDonald's frequently.- occurred over a long period of time)</span>
