While Squeaky waits for the announcement, what decision does she make?

Squeaky's just finished the big race with her rival, Gretchen. It must've been a very close-fought contest, because no one actually knows who won it. The tension is unbearable as the two girls stand around—waiting for the final results to be announced over the PA system. To add to the tension, the judge's voice is unintelligible, submerged beneath a loud crackle of static.
As she waits (for what seems like an eternity) for the results, Squeaky has something of an epiphany. During the race, she noticed that her brother, Raymond, had been running alongside the track. Although his technique had been untrained, it is clear to Squeaky that the boy has talent—the kind of talent that could be turned into something special by proper coaching. It is this kind of coaching that Squeaky determines that she will provide. From now on, she's going to put her own running career aside in order to concentrate on coaching Raymond.
