* The impermanence of life

* The destructiveness of war

Explanation:

The paragraph that is given "Want to tell you something about that boy Joe Crowell there. Joe was awful bright…graduated from high school here, head of his class. So he got a scholarship to Massachusetts Tech. Graduated head of his class there, too. It was all written up in the Boston paper at the time. Goin' to be a great engineer, Joe was. But the war broke out and he died in France. All that education for nothing."

This paragraph conveys how a very hardworking and intelligent person has seen their future destroyed and even more their life is taken away because of war, this made all of the efforts in education meaningless as the promising view for this student never became a reality.
