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'.

Premise: The region above 90 km is the Earth's thermosphere where the absorption of extreme ultraviolet radiation from the Sun results in a very rapid increase in temperature with altitude. 
 Hypothesis: As altitude rises, the temperature increases in the thermosphere.
entails

Premise: The cave populations have retained the capacity to produce fertile offspring with surface fish and are considered to be the same species (Avise and Selander, 1972). 
 Hypothesis: If two populations do not mate and produce fertile offspring, separate species result.
neutral

Premise: Heat flows from the sun to the earth via thermal radiation and from the earth to the depths of space via thermal radiation.
