Question

which statement best supports the authors claim that gaming is a legitimate sport?
gaming requires several physical skills.
large numbers of people agree that gaming is a sport.
successful gamers have formed professional gaming leagues.
diverse groups of people watch gaming tournaments on television.

Explanation:

A legitimate sport typically has organized leagues. When successful gamers form professional gaming leagues, it shows a level of organization and structure similar to traditional sports. Physical skills (first option) - gaming is more mental - skill - based in a traditional sense. Popularity (second option) - just because many agree doesn't make it a sport. Viewership (fourth option) - viewership alone doesn't define a sport.

Successful gamers have formed professional gaming leagues.
