Hello. You have presented the excerpt to which this question refers, which makes it impossible to elaborate an answer with accuracy. However, I will try to help you in the best possible way.
To paraphrase the excerpt, it is necessary, first, that the excerpt be read. After reading it, you must rewrite it keeping the message he wants to pass on to the reader, but using other words. In short, a paraphrase occurs when a text is rewritten while retaining the original meaning, but using different words.
To explain how the author constructs the argument, you must observe the supporting sentences that he presents. So you can see the structure of the text and present how the author constructed his opinions.
Answer :
A. Chekhov's use of the third-person limited point of view in "The Bet" allows him to describe the banker's self-contempt when the banker reads the lawyer's essay.
The banker had turned immoral after thinking about the consequences of the bet and intends to kill the lawyer to avoid paying him the money. The non-existent narrative voice in Chekhov's "The Bet" captivates the reader to delve into the mind of the banker and understand the feelings of self-contempt and disdain that he is experiencing upon reading the lawyer's essay.
This is math, put it in the right category.
