Text: 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.
Entailment: An approximation of running water came from an well within the structure.
Contradiction: Madame Berthelot didn't have access to water in the kitchens and had an awful stone drain.
