What is the question here? Are you asking if the translation is correct?
"¿Preguntas una chaqueta nueva para la Navidad?" means "Are you asking for a new jacket for Christmas"
I'm not sure if that helps you or not, so I'm sorry if it didn't!
la mochila is the answer to your question
12. donde
13. quienes
14. Y
Huh? I don’t know what you’re asking? How am I supposed to answer this?
