Wright includes this text for the following reason:
C.)to emphasize the hardships of single parenting.
Explanation:
The author describes a desolating scenario: two kids left alone in the household with no adults around to help or guide them in any way. They had too little to eat. All of it happened due to the fact their father was gone and their mother had to work as a cook so she was able to make ends meet (maybe not even that). If the kids' father were still around, he could either be with the kids while their mother was working or have a job as well and help financially. The parents could maybe take turns in staying home with the kids. In other words, the author made it clear that single parenting is extremely hard and painful.
