Well by reading the part "Allied forced" I'm going to assume this talk about WW2.
The first answer is about WW1, so that's obviously incorrect.
I'm not sure where the central powers come from, but I know during WW2 they joined the Axis Powers. So this is incorrect.
This sounds more like it's from WW2. Once Germany managed to invade Belgium, and other countries like Poland, that's when the allied powers started forming together. That's when Britain I believe stopped trying to "appease" Hitler. by letting him invade other countries and take control. This is correct.
The last one is most likely talking about when European countries scrambled to take control of the many countries in Africa during the 1880s. This doesn't relate to WW2, so this is incorrect.
This contributed to the industrial revolution since Great Britain had these vast sources of resource they were able to use it and find better ways to use it in industrial purposes
After the war many were demanding shorter hours and more pay because of the high prices of things.
Answer:
It would be the 2nd answer I nm pretty sure, go look on google to make sure its correct tho.
