Answer:
1) Czar you would not be happy about the revolvolution as it was supposed to remove his power. As workers you would be happy, and hope for some better rights and living conditions. The soldiers were probably tired of war, and maybe wanted to come back home.
2) A treaty should try and bring peace and stability. A classic example is the treaty of versailles where it is a cause of WW2, it broke the german economy and country with the restriction. Maybe if the treaty were better for Germany we may not have had WW2.
3) If you were germany you would be angry that all the blame is put on you. You will find it unfair you have to pay a big amount of money to the other countries. The treaty feels like a big hard push for Germany, and is a reason WW2 started, and how Hitler managed to grab the power in Germany.
I believe the answer is c hope this helps!
