Answer:
People should make the most of the opportunities that are given to them.
Step-by-step explanation:
"We Beat The Street" is an autobiography on how young people can take care of their lives, written by The Three Doctors (Dr. Rameck Hunt, Dr. Sampson Davis, and Dr. George Jenkins) and Sharon M. Draper. The book presents an autobiographical based story of three young men and how they overcame the obstacles in their lives.
In the given excerpt, the story's main theme is presented, which is that opportunities are never to be taken for granted and must be grabbed as they come. The excerpt shows the three young men being reprimanded by their teacher for not taking their studies seriously. The question "Why not fill up those four years with something valuable?" further reiterates the importance of college and studies for their future.
Thus, the central idea that this excerpt supports is that people must make the most of the opportunities that come their way.
