I want to know the answer to the following question:
When were independent states as Czechoslovakia, the Second Polish Republic, and the State of Slovenes, Croats and Serbs established?
All the background I'm provided with is that "In 1918, after World War I ended, the Slavs established such independent states as Czechoslovakia, the Second Polish Republic, and the State of Slovenes, Croats and Serbs.". Is that enough to answer the question?
Answer: yes
