Teacher: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'.
Teacher: Now, understand the problem? Solve this instance: Premise: This monocrystalline structure is very strong and produces an improvement like the difference between a brittle pencil lead and a carbon-fibre tennis racket. 
 Hypothesis: Although they differ vastly in hardness, pencil lead and diamonds both contain carbon.
