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: It is sensitive to high concentrations of urea in the external water as well as high concentrations of thiourea, a urea analogue, which causes a decrease of urea influx, consistent with the hypothesis of a bi-directional transporter (Wood et al. 
 Hypothesis: Animals can transport the waste material known as urea in the circulatory system and store it safely at high concentrations.

SOLUTION: neutral
