22) In a golf tournament, 256 participants are competing. The tournament is structured such that in each round, 4 participants compete: the winner advances to the next round while the other 3 participants are eliminated. How many rounds are necessary to determine the absolute winner of the tournament?
(A) 16
(B) 64
$\begin{array}{ll}\text { (C) } 65 & \text { (D) } 85\end{array}$
(E) 128.
22) The answer is (D).

Indeed, to determine the absolute winner, it is necessary to eliminate 255 contestants. Since 3 contestants are eliminated in each round, the answer is $\frac{255}{3}=85$.
