Do my opening sentences make sense (Great Gatsby essay)?

Okay, you get good marks for using words aptly and making an articulate argument using as few words as possible.

Short words can be used to describe very complex concepts its just sometimes there is a longer word that means you can say it faster, if so you get bonus points for having a good vocabulary.

However its is not like a game where you get a combo bonus if you have 5 words in a row that are over 7 letters, no it doesn't make sense, yes you sound like an idiot. Use words you know the meaning of and say something worth saying, thats how you get good marks.

Also your title kinda sucks, i don't know if you chose it or it was given to you but its quite bland.

So if i was writing an essay that had to be titled Gatsby's roaring twenties I'd start it:

The fast money and high spirits of a post war America lead to a increasingly materialistic and hedonistic society, among this "foul dust" only one character managed to rise above the corruption and try and achieve something pure, to live The American Dream.

So that wasn't as good as I thought it was gonna be...i didn't put much thought into it and like i said your title makes it hard to say something interesting. if you just want you title reworded try

Carelessness, prosperity, hard work, and opportunity are characteristics that are central to the free thinking 1920’s. These distinctive traits exemplify the typicality of the reoccurring trends that embody the American Dream of this decade.

Sorry i can't make that make sense its a train wreck, its beyond saving, start again and use words you understand
