¿qué hiciste en las mañanas? a. tuve que ir a la escuela. b. creo que estuve enfrente del monumento.

Since someone wants to know what I do in the morning, then I need to answer this question in the preterite tense. This tense is used to describe actions that took place or were completed at a certain point in the past. The word tuve comes from the verb tener and is the conjugation of this verb for the first person singular in the preterite. Finally:

- ¿Qué hiciste en las mañanas?

- Tuve que ir a la escuela.

i think the answer is clothing store
