I want to know the answer to the following question:
What percent of Armenias commodities were transported via rail traffic?
All the background I'm provided with is that "The initial post-Soviet years were marred by economic difficulties, which had their roots early in the Karabakh conflict when the Azerbaijani Popular Front managed to pressure the Azerbaijan SSR to instigate a railway and air blockade against Armenia.". Is that enough to answer the question?
Answer: no
