According to the conversation, what is one of the driving forces of shooting?

W: It is hard for me to believe that [3]shooting is one of the most popular sports in the world.
M: I believe this is true. In Europe, shooting is open to men and women and even children of all ages for recreation.
W: Even children?
M: Yes.
W: Shooting requires technical perfection and excellent mental conditioning. [1]I think one of the driving forces of shooting is the desire to conquer and control other people.
M: I agree. Just like the early days in America, the white settlers or the pioneers used guns to control and conquer Native Americans, which became one of the most popular and favorite movie themes in the U.S.
W: I am an American western movie fan.
M: I know you are.
W: The format of the Olympic shooting competition has changed greatly over the years. [2]I understand that Men’s Shooting was one of the nine sports of the first Modern Olympic Games in Athens in 1896.
M: Shooting has grown steadily since it became an official game at the Olympics. When it was first introduced in Athens in 1896, there were only three rifle and pistol events.
W: How many events are there nowadays?
M: Shooting events have gone through constant changes over the years. After World War Ⅱ, this Olympic event became more regular and it now stands at seventeen events.
