Also, the user might be a student looking for study help, possibly in a non-English speaking country, so the write-up should be in Spanish. But the user provided the request in English, so maybe they want the initial draft in English. Wait, the query is in Spanish but the request is in English. Maybe the user wants a draft in Spanish. Hmm, the query starts with "solucionario..." which is Spanish, but the last line says "draft a write-up" in English. Confusion here. The user might be asking for a Spanish write-up on their query. However, since the initial instructions are in English, maybe they want the draft in English. Need to check the initial instructions again.
