Given the task definition and input, reply with output. You are given two sentences. You have to find if there is entailment or agreement of the Hypothesis by the Premise. From the given pair of sentences, you should identify if there is enough information in the Premise to support the claim made in the Hypothesis. The Premise may not exactly be the same as Hypothesis. Your task is to return 'entails' if the premise supports hypothesis else return 'neutral'.

Premise: It is not the formation of hydrogen sulfide that is toxic to the cell but the process of reducing the sulfur that results in toxicity. 
 Hypothesis: Hydrogen sulfide is a noxious and toxic gas produced from decaying organic matter that contains sulfur.
