To Illustrate the Dimensions That All Objects Possess, the Textbook

To illustrate the dimensions that all objects possess, the textbook discusses a "shiny new bicycle." Why is this example useful to illustrate dimensionality?

A) Bicycles have been around for a while, but they are becoming an important commodity since Americans started producing them in factories again.
B) Actually, any object would do just as well, but most Americans are familiar with bicycles.
C) The latest iPhone would have been a better choice because it would emphasize the latest technology.
D) Bicycles are typically only available to the highest social classes in any society.
