In order for me to help you with this one you'll have to write down the answer so I can translate it
1. ¿Juegas con él? Sí, juego mucho con él.
2. ¿Puedo ir al parque? Sí, yo tambien puede ir.
3. ¿Duermes mucho? No, yo nunca duermo.
In Spanish a personal A used when the direct object is a person
Example: Brooke llama A Elsa
In English this means Brooke calls Elsa
But in Spanish it is being use mostly at a person but can also be use at an object
Hope this helps :3
