Answer:
Burning a book connects to Fahrenheit 451 because it is essentially the loss/withholding of knowledge that could have benefited someone or a group of people.
Step-by-step explanation:
Well, the question seems to be pretty oddly phrased, since there are several reason for the burning of books in Fahrenheit 451. However, the main reason was for the government to have control of the public's thoughts. This can further be broken down to the reasons of "offensive material" and "different levels of intellect" which were caused by the simple act of reading, that may have hurt people's feelings.
What I'm assumming the question is asking is "how does burning a book in real life connect to these motives in the story".
In addition, we have also seen mass book burnings in real life. One such example is the book burnings in Nazi Germany and Austria within the 1930s, which were done if a book was seen to oppose Nazism.
