Final answer:
The sentence emphasizes Hoover’s impactful humanitarian work after World War I through international recognition, contrasting his international acclaim with his later domestic challenges.
Step-by-step explanation:
The sentence "In Belgium and Poland, city squares and streets were named after Hoover, and he was showered with honorary university degrees and other high awards," contributes to the author's description of Herbert Hoover's work after World War I by highlighting the international recognition and appreciation for his humanitarian work. Despite his later unpopularity in the United States due to the handling of the Great Depression, Hoover's previous efforts in providing relief to war-torn Europe were highly regarded. This illustrates a great contrast between Hoover's domestic and international legacies, suggesting that while he may have struggled to manage domestic issues, his impact on international relief was significant and positively remembered.
