Take the following as truth: And this is just what did happen, in the shape of a communication, which arrived by the second post from a firm of French music publishers, acknowledging Mrs. Inglethorp's cheque, and regretting they had been unable to trace a certain series of Russian folksongs. 
Then the following statement: "Although the French firm of music publishers tried to trace a series of Russian folksongs, they didn't speak Russian and were unable to do so." is true, false, or inconclusive?
Answer: Inconclusive
