Read the excerpt from "Broken Chain."

Alfonso walked over to his brother. He compared their two bikes: His gleamed like a handful of dimes, while Ernie’s looked dirty.

Why does Soto most likely include this image of Alfonso’s bike?

to support the idea that Alfonso rarely uses his bike
to show how much Alfonso wants to impress his brother
to emphasize how much Alfonso cares about appearances
to reveal that Alfonso spends a lot of money on his bike
