Analyzing Chapter One of The Great Gatsby

Within the first chapter of F. Scott Fitzgerald's The Great Gatsby, the reader can already see many plot elements beginning to take shape.
The first chapter of the novel chronicles the scene and environment that Nick Carraway arrives to in the "West Egg" portion of Long Island, New York. The residence that Carraway moves into in Long Island is situated next to "Gatsby's mansion", although there is of yet no meaning or explanation as to who Gatsby is or why his home should be of any significance. After settling into his home Carraway makes a journey to "West Egg" in order to visit his cousin Daisy and her husband Tom Buchanan. While there, Carraway also meets Jordan Baker, a competitive golfer whom he is encouraged to take romantic interest in. At the very end of the chapter, Carraway encounters Gatsby for the first time, with his arms spread out over dark water. Gatsby's purpose in the story as well as what he is doing at the lake are left unanswered at the end of the chapter.
