In this problem, we'll use two tenses:
- Preterite Tense Forms. The preterite tense is one of two simple past tenses. It is used to describe actions that took place or were completed at a certain point in the past.
- Present tense. The simple present tense is used to talk about habitual actions or routines. This tense is also used to describe things that happens now or in the near future.
