Answer:
It shows that there were white citizens who treated African American citizens in unjust and humiliating ways.
Explanation:
In <em>Roll of Thunder, Hear My Cry</em> we follow the story of the Logan family through the lives of all of its members. The abuse on a racial basis that is described in the given excerpt was just one of the minor discomforts that African Americans experienced, or in this case - the Logan family. From being beaten, falsely accused of doing something they did not do, to not being served in a store or getting second-hand books from white schools that were too old and useless<em>. </em>So, in this novel, we have a very detailed and realistic description of the everyday life of average African Americans and how they coped with it.

B is most likely for how I can see it.
