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: Ocean acidification (OA) is the process by which anthropogenically derived atmospheric carbon dioxide (CO2) is absorbed into surface seawater, lowering the pH and concentration of carbonate ions in the global ocean (Caldeira and Wickett 2003 ; Doney etal. 2009 ).
Hypothesis: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic.
entails

Premise: Silyl enol ethers in organic chemistry are a class of organic compounds that share a common functional group composed of an enolate bonded through its oxygen terminus to an organosilicon group.
Hypothesis: An ether is an organic compound in which two hydrocarbon groups are bonded to the same oxygen atom.
neutral

Premise: It was purely a matter of making the truth known.
Hypothesis: Elements are pure substances that make up all matter.
neutral
