Which of the following Kuotations by Huck's father in chapter 5 of The Adventures of Huckleberry Finn is an example of irony?
"Starchy clothes--very. You think you're a good deal of a big-bug, DONT
you?"
"You're educated, too, they say—can read and write. You think you're better'n your father, now, don't you, because
he can't?"
"And looky here—you drop that school, you hear? I'll learn people to bring up a boy to put on airs over his own father
and let on to be better'n what HE is."
"All right. I'll ask him; and I'll make him pungle, too, or I'll know the reason why.

"And looky here—you drop that school, you hear? I'll learn people to bring up a boy to put on airs over his own father  and let on to be better'n what HE is."

Explanation:

In chapter 5 of The Adventures of Huckleberry Finn, his father is a vile man who was jealous of Huckleberry for having been the first person in the family to become literate especially whilst he himself was not.

He therefore resolves to end Huckleberry's education and tells him to stop going to school or else he would beat him and show people not to make a boy to become better then his father or his true self which is ironic because that is what education is meant to so, make a person better.  

when i skim a text i look for anything i'm trying to find, like keys or clues or i just want to see if it is interesting to me.

explanation:

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
