You will be given a definition of a task first, then some input of the task.
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: At some sites they expect it to take up to several decades or more to be able to clean up and then at least control where the contamination is moving and then to minimise any potential for people's ground water and drinking supplies to be contaminated. 
 Hypothesis: At least 20 percent of the world’s people do not have a ready supply of clean drinking water.
Output:
neutral
