Answer:
The preterite tense is one of two simple past tenses. We use it when describing actions that took place or were completed at a certain point in the past, so we need to write sentences with the preterite tense of the verb hacer to say what Alberto and his family did during their last trip and what the weather was like. So we are given three words to solve this exercise, namely:
hacer
calor
sol
Let's write some sentences:
1. En sus últimas vacaciones Alberto y su familia hicieron un viaje por las islas del caribe.
Here hicieron is the conjugation of the verb hacer for the third person plural in the preterite.
2. En dichas islas hacía extremandamente calor.
Hacía is the conjugation of the verb hacer for the third person singular in the preterite. Moreover, we use calor here, so hacía extremandamente calor means it was very hot
3. El sol hacía que nuestras bebidas se calentaran rápidamente
Here we also use hacía because the subject is el sol that stands for the third person singular.
