The better response to the question "¿Qué hiciste en las mañanas?" would be:
a. Tuve que ir a la escuela.
Explanation:
1. The question is asking about what Orlando did in the mornings. The response "Tuve que ir a la escuela" indicates that he had to go to school, which directly answers the question about his morning activities.
2. This response provides a specific and relevant detail about Orlando's daily routine during his time as an exchange student in Santo Domingo.
3. The other option, "Creo que estuve enfrente del monumento," does not address what Orlando did in the mornings and is not as directly related to the question asked.
