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: Therefore during many chemical reactions involving molecules that have Pi bonds and sigma bonds , the Pi bond breaks without disturbing the sigma bond. 
 Hypothesis: Catabolic reactions involve breaking bonds.
Student:
