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: The climate is rather severe, the winters are long and very cold, with temperatures going down to -30C, Summer is short and cool. 
 Hypothesis: Exemplified by canada and alaska, a subarctic climate has cool, short summers and long, cold winters, little precipitation, and abundant conifers.

SOLUTION: neutral

PROBLEM: Premise: Usually atoms have equal numbers of protons and electrons, which means that they are electrically neutral, and therefore normally no electric forces are present. 
 Hypothesis: Because atoms have equal numbers of positive protons and negative electrons, they possess a neutral charge.

SOLUTION: entails

PROBLEM: Premise: Within the past 200 years or so, increased amounts of carbon dioxide and other greenhouse gases have been released into the atmosphere due to human activity. 
 Hypothesis: The composition of the atmosphere has changed over the last 200 years primarily due to human activity.

SOLUTION:
entails
