Su is used to show possession of singular objects, in this case, a t shirt, in third person form.
Answer: 1. caminando en el bosque, 2. voy a descansar
Explanation:
1. The verb needs to become a present participle since it is using estar.
2. The statement says, "I am walking in the forest," so the most reasonable answer would be, "Tomorrow, I am going to rest."
