Answer:
Tú trepabas ese árbol.
Explanation:
When you say "ese" you mean "that." So in translation, "You climbed the tree over there" in spanish would be this answer because you are talking about a specific tree not next to you. I don't know if I worded my explanation correctly, but I hope it helps.
I believe the answer is quién. Quién means who.
It means smallness or affection when you can ito/ita
