Answer: the broken-down horseless carriage
Explanation:
Dragonwings, by Laurence Yep, is the story of Moon Shadow, a Chinese boy who goes from China to San Francisco's Chinatown to be with his father. There, he learns that white Americans, who often discriminate against Chinese immigrants, are referred to as white demons. In the setting of the story, the boy´s father offers to help a man (a white demon) whose horseless carriage has become stranded.
The t-shirt that they give only to people who finish is a big reason that so many people take up the challenging race.
This paraphrase presents the same information as in the sentence, but since it should be a bit more of a summary, it takes out the specific detail of how many people actually run the race, which can just be paraphrased into 'so many'.
