Answer:
With the Americans Joining the war, the spirit of the German people began to crumble
Explanation:
The war had been brought to a complete standstill between the central powers and the Triple Entante, The Germans were already being prepared to bail out of the war, but so were its enemies. However, when America joined the war, the allies got a second wind, and the German's morale and hopes of winning were eminently crushed. With the arrival of fresh troops into France, and new tactics and weapons like the Trenchgun or the M1 Flamethrower, Germany eventually threw in the towel before things got worse.
The creation of interchangeable parts greatly changes the labor force during the 1800's. Interchangeable parts allows for a standard size of goods (clothes, furniture, etc.). Due to this change, the workforce transformed from a demand for skilled workers to unskilled workers. With interchangeable parts, there was no longer a need for individuals to make everything from hand. Instead, businesses were able to mass produce products with the help of unskilled workers. These workers were usually taught a specific, repeatable task. As long as the unskilled worker was able to learn this task, they would be able to keep their job. This revolutionizes the workforce for over 100 years, as the addition of the assembly line along with interchangeable parts results in the creation of products at a rate never seen before in world history.
