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: Many species of birds have at least four or five louse species.

SOLUTION: neutral

PROBLEM: Premise: The proposal that Mars, early in its history, had some complement of water and an atmosphere of carbon dioxide and nitrogen much more dense than today is not unreasonable. 
 Hypothesis: During the early paleozoic, the amount of carbon dioxide in the atmosphere was much greater compared to today.

SOLUTION: neutral

PROBLEM: Premise: Gas is defined as a formless fluid that expands readily to fill any containing vessel, and which can be changed to the liquid or solid state only by the combined effect of increased pressure and decreased temperature. 
 Hypothesis: When the solubility of gases in liquids changes with increasing temperature, it decreases.

SOLUTION:
neutral
