The differences between driving your private car and taking buses were well adapted in the essay. You compared these two in many logical aspects. Briefly, the structure of your essay is favorable for a comparison/contrast essay, I think. When it comes to the grammatical elements in the essay, there are some mistakes to be corrected:
1) We use singular forms of words after “every”. In the first sentence, “every people” should be corrected as “every person”
2) There is a punctuation mistake in the first paragraph. “peoples’ private cars” is to be turned into “people’s private cars” as “people” is plural itself.
3) The sentence, “Both two way of transportation has their pros and cons.” has grammatical mistakes. “Both two ways of transportation have their pros and cons.” is the corrected form.
4) With the sentence “there are not any people apart from themselves”, I couldn’t see what you mean.
5) The sentence “there would be chaos in traffic jam.” seems to be unlogical. “Traffic jam” already involves the negative meaning the “chaos” has. So, “there would be a traffic jam” or “there would be a chaos in traffic” may be preferred instead.
This quotation comes from Chapter 8. As Ponyboy sits in the hospital and watches Johnny dying, he muses on the fragility of group cohesion. It seems obvious that Johnny needs the greasers—he is small, passive, and poor, which makes him an easy target of Soc violence. Less obvious is the gang’s need for Johnny. The greasers need a vulnerable friend to give them a sense of purpose. Telling themselves that they exist to protect people like Johnny lets them avoid thinking about the fact that their poverty and vulnerability leave them no choice but to band together. Ponyboy comes to this conclusion at the end of the novel, as Johnny is dying. He understands Johnny’s value only when he is about to lose Johnny, which amplifies the pain of the loss.
