Shes crying because she has only $1.87 to buy her husband a present so we should assume that its the first one.
Basically, this quote means that you should do what's best for you even if the choices you make might hurt someone else. It also states that you need to do things that are in your best interest, even if they hurt and are painful because at the end of the day you are the most important person and you deserve to be happy.
The opening chapter of the book Frindle focuses on introducing us to the main character Nick Allen, an imaginative boy who likes to brighten up his school by figuring out unique and unusual ideas, an example would be that in 3rd grade, he turned the classroom into a tropical island by making paper palm trees and having everyone wear beach clothes.
While Colonel Pickering is not what all would consider to being a "true gentleman", he is the closest to it. He has more respect toward Eliza than Higgins, whose only concern is for himself. Doolittle is only a selfish, terrrible father, and Freddy is not in love with Eliza, but merely wants to use her. Thus Colonel Pickering is the closest character to being a "true gentleman".
The hook is usually the sentence which occurs toward the beginning of the paragraph. It's main objective is to catch the readers attention and make them want to continue reading. (It's kind of like the thumbnail of a Youtube video, it catches the viewers attention.) Anyway, now that we have reviewed what a hook is, let's use the process of elimination to find our answer. A. cannot be the answer. It is a part of the beginning of the passage. It also is a fact, and is not written in a way that can attract a reader's attention and make them want to continue reading. The same goes for B. This is simply just not something that would attract a reader's attention. C is also not the answer. Once again, this statement fails to attract the reader's attention. So, this leaves us with the correct answer, D. Not only is this the first sentence in the paragraph, it also attracts the reader's attention and makes them want to read the rest of the passage.
