Final answer:
North Carolinian troops contributed significantly to World War I by helping to defeat German forces at a crucial turning point and uniting soldiers from different states, but less than 10% of them lost their lives, and not all single young men volunteered, as many were conscripted.
Step-by-step explanation:
The contributions of North Carolinian troops to World War I are numerous, but the statement that more than 10% of troops lost their lives during the war is not accurate. Based on the numbers provided, out of 86,000 soldiers approximately 2.3% died from wounds or disease, which is significantly lower than 10%. However, the soldiers from North Carolina indeed helped to defeat German troops at a significant turning point in the war. This was achieved in part by the troops of the “Old Hickory” division, which was primarily composed of North Carolinians and played a crucial role in breaking the German defensive line. Moreover, considering that North Carolinians fought in units with soldiers from other states for the first time, they did indeed assist in uniting troops from different states as part of the war effort. The claim that all single young men volunteered to fight is incorrect because the government instituted a draft, which means that many were conscripted rather than volunteered.
