4)“Mindless entertainment would replace recreational free thinking.” With reference to the film Fahrenheit 451, and maybe SUAS, can you provide evidence for this statement?

I don’t think the Mindless entertainment would replace recreational free thinking. The mindless entertainment as a popular juke permeates our life present. I did not watch it frequently because it might addict my brain loss the activity.
In the film of Fahrenheit 451, books were forbidden in their society. The citizens could not read the books, and then they use strange television. In Fahrenheit 451 when Linda was watching television, she answered questions from the TV show, then she got feedback form the mindless TV show.
In SUAS Natalie had spoken "Just so you know, we’re ashamed that the President of the United States is from Texas." after this speech, she lost her fans because of the mindless report of the Media. I think the Media just want to make a news to entertain people, they are exaggerated the speech of Natalie.
