Answer:
My name is Anthony Chen, and this is my manifesto as a dining hall prefect.
First of all, I have a three-point agenda to sanitize the dining hall, thus making it more conducive for students. The three points are:
1. Ensuring high quality meals are served in the dining areas
2. Making sure the dining hall is clean at all times. (There will be punishment for defaulters.)
3. Ensuring meals are eaten in peace and love.
It is important that not only healthy foods are served in the dining hall, but also that no essential nutrient is lacking at any given time.
Also equally important is ensuring cleanliness at all times because a dirty place breeds germs faster.
Finally, as the Holy Bible says, "better a meal eaten in love, than a banquet where there is strife". There shall always be peace and love among students.
The correct answer is reflexive.
Reflexive pronouns are used when the object of the sentence is the same person as the subject. Here, the subject is Johnny and given that he bought something for himself, he is also the object. Although the pronoun himself can sometimes be intensive, this is not the case where it is. Intensive pronoun would be if the sentence said: Johnny himself bought a new basketball.
It's been a while since I've read the book and I don't really a lot of the context, so just from this passage I would say it says he notices nice houses and other people's wealth and maybe envies them a little bit. (although you don't get that explicitly from this passage.)
