Given the task definition and input, reply with output. 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: It was only in the 1950s that cell biologists put the two lines of research together, the work of the membrane biologists and the work of the structural biologists using electron microscopy, to form a new concept of the cell membrane applicable to all biological systems. 
 Hypothesis: Two membranes form the mitochondrion structure of a cell.
