I would say the theme is that when a child grows up, what his/her circumstances are determines to a large degree how they will fare in life. In this case the girl was abandoned by her father and her mother couldn't look after her because she had to work so her daughter had to be brought up by relatives. Also, she is described as dark so perhaps dark skinned which would make her a target for racism if say in Canada or the US. Dr Gabor Mate, a medical doctor in the downtown eastside of Vancouver, BC Canada says that, for example, drug addicts have most often had a terrible upbringing so they have sought relief from the emotional and physical pain with narcotics. For example, one baby was kept in the dryer with a weight on the lid while his mom went to bars to pick up men.
The political parties of the United States have always been formed around a particular issue or desire of people. For example, the Federalist party was formed due to the issue of the ratification of the Constitution, while the Free Soil party was formed as a way to oppose the expansion of slavery in the West. Each political party has represented different needs of the population. This is what colonists wanted from Great Britain prior to the Revolution. Before the war, Americans could not have different opinions in politics, or hope that their views were represented in the political arena.
I believe the answer is B
