根据下面材料，回答题：Television has opened windows in everybody's life. Young men will never again go to war as they did in 1914. Millions of people now have seen the effects of a battle. And the result has been a general dislike of war, and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen.
Television has also changed politics. The most distant areas can now follow state affairs, see and hear the politicians before an election. Better informed, people are more likely to vote, and so to make their opinion count.
Unfortunately, television's influence has been extremely harmful to the young. （76）Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements he to sell products that are sometimes bad or useless. They believe that the violence they see is normal and acceptable. All educators agree that the "television generations" are more violent than their parents and grandparents.
Also, the young are less patient. (77) Used to TV shows, where everything is quick and interesting, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen, or thirty minutes. That's the time it takes on the screen.

B．went in for politics
C．liked to save the wounded in wars
