Answer:
Describe your apartment and accurately describe your room
Explanation:
Andreas fährt gern am Samstag ins Route 66.
So it’s in this order: Wer, Verb, Wie, Wann, Wohin.
But you have to match up Wie + Wohin so that they make sense. And if the Wer is more than one person, the Verb has to match.
Answer: ihn
The pronoun has to be masculine (der Nachtisch) and accusative form, which is "ihn."
The internet slang term ja refers to the meaning yes in this instance.
