Explanation:

For Question 15: The U.S. Senate rejected the Treaty of Versailles, so the U.S. never joined the League of Nations and ended WWI via separate peace treaties with Germany, Austria, and Hungary in 1921, making this the correct outcome. The other options are factually incorrect: there was no such student exchange, the U.S. did recognize Germany, the Austria-Germany alliance was not a direct result of non-ratification, and the 1941 war declaration was unrelated to this treaty issue.
For Question 16: In May 1915, the British ocean liner Lusitania was sunk by a German U-boat, resulting in the deaths of 128 American civilians, which escalated tensions between the U.S. and Germany during WWI. The other ships listed were not sunk in this event with this death toll.

Answer:

Question 15: a. The United States did not officially end the war until 1921
Question 16: e. The Lusitania
