Step-by-step explanation:
The given sentence, "¿Preguntas una chaqueta nueva para la Navidad?", is grammatically incorrect. The correct form of the sentence should be, "¿Pides una chaqueta nueva para la Navidad?". In Spanish, the verb "preguntar" means "to ask", while the verb "pedir" means "to ask for" or "to request".
