The correct answers to these open questions are the following.
1.-Based on the timeline, describe the progress of the war between 1914 and 1917.
After reading the information on the timeline, we can say that there was little progress during those years and many casualties on both sides, the allies, and Germany. We can support this affirmation using the examples of the Battle of Verdun and the Battle of the Somme. In both battles, historians say that there were two million casualties. The war at the trenches made things more difficult.
2. What effect did the United States’ entrance into the war have?
It completely changed the situation, The war had become a halt. And the United States' entry represented more troops for the Allies and more money and war supplies. This changed the situation in favor of the Allied Forces.
Let's remember that originally, US President Woodrow Wilson had decided to remain neutral in World War I. However, the interception of the Zimmerman telegram and the sinking of the Lusitania ship by the German Navy forced President Wilson to ask Congress for a declaration o war against Germany.
