Among the choices above, the answer, "It helps readers understand and identify bronze sculptures" qualifies as a sidebar because it guides the readers in indicating which is a bronze sculpture. This kind of technique needs guidance because not everyone knows how to determine bronze sculpture from other types of sculptures. It also has to be detailed.
