mexico is where it was common
Explanation:
B an investigative journalist exposing corruption
Answer:
The answer would be C. Germany and Russia.
Germany was excluded because she lost WW1 against The Allied Forces and Russia didn't join The League Of Nations because she retreated from the war before the war actually ended.
In short, Germany was close to being defeated, and America wanted to be part of the post war carve up (when territory was divided). The US was supplying war materials to the Allies and could not do so while maintaining complete neutrality. There was also the sinking of the British ship Lusitania which angered the US. Also, the Zimmerman telegram.
