unit test help plz timed

Once I traveled about in an old bakery wagon, double-doored rattler with a mattress on its floor. I stopped where people stopped or gathered, I listened and looked and felt, and in the process had a picture of my country the accuracy of which was impaired only by my own shortcomings. What is the purpose of the description in this passage from Travels with Charley?
A to show that he prefers the bakery wagon to the camper to show the authentic experience of traveling in a casual way
B to show that Americans like baked goods
C to show that he is not a very good writer
