C. rant
He went into a long rant about the outcome of the election after it was mentioned on the news.
assert and fastidious are not nouns, which is what the sentence is asking for "a thing", so they are not the correct answers. As well they only mention one person in the sentence and quibble is an argument, which needs more than one person. Therefore it is not likely to be the correct answer. A rant is a long tirade by one person, it fits the best within the sentence.
he continue hurazzing the dragon in is being mean!
B because it has -ing at the end of the word which means you are currently doing it
B) mainly
The word "mainly" shows that the story of Huck Finn is more fiction than fact. He repeats this word many times when he is talking about the story being one of truth. This intensifier introduces the idea of the story being a bit exaggerated and fictional. The other words add to the characterization of Huck. He uses ain't simply to mean isn't. When he says "that ain't no matter" he means that it is no big deal. Without is used to mean exactly that and is not meant as an opposite.
