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 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: 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.
entails

Premise: Tornadoes Tornadoes are most common during the period of spring and early summer, but can occur in any month of the year.
