GMAT Practice Question Set #23 (Question 67-69)

Critical Reasoning Question #69: Scoring Points  
Time 0 0 : 0 0 : 0 0
Debater: The average points scored per game by a player on the starting roster of the New York Boomerangs is 12 points. Most players of the New York Boomerangs are on the starting roster. Furthermore, the average points scored per game by any player on the team generally does not fluctuate much from game to game. Therefore, each game, most players of the New York Boomerangs almost certainly score at least a few points.
 
The debater's argument is most vulnerable to criticism on which of these grounds?
(A)
It takes for granted that the starting roster is representative of the overall team with regard to the average points scored per player each game.
(B)
It takes for granted that if a certain average of points is scored each game by each player of the New York Boomerangs, then approximately the same amount of points must be scored in each game by each player of the starting roster.
(C)
It confuses a claim from which the argument's conclusion about the New York Boomerangs would necessarily follow with a claim that would follow from the argument's conclusion only with a high degree of probability.
(D)
It overlooks the possibility that even if, on average, a certain amount of points is scored by the members of some group, many members of that group may score no points at all.
(E)
It overlooks the possibility that even if most players of the team score some points each game, any one team player may, in some games, score no points.
