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: cementite, sometimes called iron carbide, a hard compound of iron and carbon and other carbide-forming elements; 
 Hypothesis: Binary compounds of carbon with less electronegative elements are called carbides.

SOLUTION: neutral

PROBLEM: Premise: pH In chemistry, pH is a measure of the concentration of hydrogen ions in a solution, which is a measure of acidity or alkalinity. 
 Hypothesis: The concentration of the hydrogen ion in a solution can be calculated when the ph is known.

SOLUTION: entails

PROBLEM: Premise: Tone of solution is defined as effective osmotic pressure Only molecules not permeable across the membrane contribute to a solutes tone Principles of osmosis continue to apply except now water diffuses to the greatest effective osmotic pressure 
 Hypothesis: Applying a pressure greater than the osmotic pressure of a solution will cause reverse osmosis.

SOLUTION:
neutral
