Take the following as truth: Mon ami, he said, turning to me, "somebody stepped on that cup, grinding it to powder, and the reason they did so was either because it contained strychnine or, which is far more serious, because it did not contain strychnine!" I made no reply. 
Then the following statement: "I replied that the cup was certainly stepped on because it did not contain strychnine." is true, false, or inconclusive?
Answer: False
