Which two parts of this excerpt from F. Scott Fitzgerald's "Winter Dreams" helps build anticipation in the story? Dexter put on his bathing-suit and swam out to the farthest raft, where he stretched dripping on the wet canvas of the springboard.There was a fish jumping and a star shining and the lights around the lake were gleaming. Over on a dark peninsula a piano was playing the songs of last summer and of summers before that—songs from "Chin-Chin" and "The Count of Luxemburg" and "The Chocolate Soldier"—and because the sound of a piano over a stretch of water had always seemed beautiful to Dexter he lay perfectly quiet and listened.The tune the piano was playing at that moment had been gay and new five years before when Dexter was a sophomore at college. They had played it at a prom once when he could not afford the luxury of proms, and he had stood outside the gymnasium and listened. The sound of the tune precipitated in him a sort of ecstasy and it was with that ecstasy he viewed what happened to him now. It was a mood of intense appreciation, a sense that, for once, he was magnificently attune to life and that everything about him was radiating a brightness and a glamour he might never know again.
