In what way were the public responses to the influenza pandemic and the Red Scare after World War I similar reactions to very different problems?

The correct answer is D. • growing fear of others.

Both the influenza pandemic and the Red Scare after World War I were met with significant public anxiety and fear, albeit in different contexts. The flu pandemic led to fear of the disease and its spread, as well as fear of those perceived as carriers or those not complying with public health measures. Similarly, the Red Scare created a widespread fear of communism and perceived threats from radicals and immigrants, resulting in suspicion and hostility toward certain groups. In both cases, fear influenced public behavior and policy, leading to increased social tensions.
