Take the following as truth: Madame Berthelot had the large vaulted kitchen built almost on a level with the river, so that an indoor well provided the closest thing to running water, and an unusually hygienic stone drain sent back the slops.
Then the following statement: "The muddy river often yielded wet clay used to fashion kitchenware for the estate." is true, false, or inconclusive?
Answer: Inconclusive
