Answer :
The relatively low casualty rate suffered by the United States during World War I can be explained by the fact that the United States entered the war near the end of the fighting.
Specifically, the United States joined the conflict in April 1917, while the war ended in November 1918. This means the total duration of U.S. involvement in World War I was approximately 1.5 years. In contrast, many other countries had been involved since the war started in 1914, resulting in a duration of about 4 years for them. Due to this delayed entry into the war, the United States experienced fewer casualties compared to other countries that were involved in the war for a longer period.
Therefore, the correct statement is:
The United States entered the war near the end of the fighting.
