Question 13
Sixteen beavers play four rounds to determine ranks 1–16. At every round, each group splits into equal winner and loser groups: winners go left and losers right. The process continues as shown.
“Vòng” means round and “Thứ hạng” means rank. A beaver winning rounds 1,2 but losing rounds 3,4 is ranked 4. If Noro loses exactly one round, which ranks could Noro obtain?
