TASK DEFINITION: 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'.
PROBLEM: Premise: Binary compounds such as tungsten carbide or boron nitride can be very refractory.

PROBLEM: Premise: When the muscle moves forward (towards the animal's head), it causes the lungs to compress and force air out (exhale), thus ridding the body of used air.
