Final answer:
The question is asking for an answer using indirect and direct object pronouns. The answer is 'Sí, os lo explico.'
Step-by-step explanation:
The question is asking for an answer using indirect and direct object pronouns. In this case, the direct object pronoun is 'el mensaje' (the message) and the indirect object pronoun is 'nosotros' (us).
The sentence '¿Explicas el mensaje a nosotros?' can be answered using indirect and direct object pronouns as follows: 'Sí, os lo explico.' Here, 'os' is the indirect object pronoun representing 'a nosotros' and 'lo' is the direct object pronoun representing 'el mensaje'.
So the answer to the question using indirect and direct object pronouns is 'Sí, os lo explico.'
