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: For a current to flow, there must be a circuit, an unbroken loop for the charge to follow, and a driving force. 
 Hypothesis: Because charges must have an unbroken path to follow, electric current cannot flow through a material unless it forms a closed loop.
