Take the following as truth: You could just ask him what he makes of, say, van Pelt's assertion that the answer to the riddle of the gas chambers was all over the archives, or what he thought of the chemist's declaration that the test performed for cyanide was the wrong test.
Then the following statement: "Van Pelt says gas chambers could be explained in the archives." is true, false, or inconclusive?
Answer: True
