The lasting effects of the Vietnam War include:
- Hundreds of thousands of soldiers suffered physical and emotional scars from the war.
- Americans were divided over whether the war was worth fighting.
The other two responses are not accurate in their lasting effects:
- American soldiers helped to solidify a lasting democratic government in South Vietnam. (This is incorrect, as South Vietnam ultimately fell to the North in 1975, leading to the reunification of Vietnam under communist control.)
- The Vietnam War stimulated the United States’ economy. (While there were short-term economic effects, the war also led to significant economic challenges, including inflation and budget deficits in the long term.)
Therefore, the correct responses are the first two options.
