I want to know the answer to the following question:
Along with the Ukrainian Soviet Socialist Republic and Byelorussian Soviet Socialist Republic, what state joined Russia to form the Soviet Union?
All the background I'm provided with is that "On December 30, 1922, the First Congress of the Soviets of the USSR approved the Treaty on the Creation of the USSR, by which Russia was united with the Ukrainian Soviet Socialist Republic, Byelorussian Soviet Socialist Republic, and Transcaucasian Soviet Federal Socialist Republic into a single federal state, the Soviet Union.". Is that enough to answer the question?
Answer: yes
