I believe the correct answer is <span>to portray Huck's father as uneducated and ignorant. Huck's father is telling his son that he shouldn't go to school because it makes him think he is better than his own dad. He is stupid and rude and wants to deprive his own son of education and a better life, which doesn't involve theft and crime. </span>
Independent clause this is because they is the subject , know is the verb so simply is the adjective. all a sentence need to stand on its own is a noun and a verb :)your welcome
