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'.
Example: Premise: Lyme Disease is caused by a bacterium that's transmitted by tick bite, but many infected people don't remember a bite. 
 Hypothesis: Lyme disease is caused by bacteria.
Example solution: entails
Example explanation: The premise sentence agrees with the hypothesis that Lyme Disease is a bacterium. The premise also gives additional information about Lyme disease. Therefore Premise entails Hypothesis.

Problem: Premise: Professor Robert van der Hilst and his collaborators demonstrated conclusively that convection in the Earth's mantle involves tectonic plates sinking from Earth's surface deep into the lower mantle and later found evidence for compositional stratification at larger depth than hitherto thought. 
 Hypothesis: Rises then sinks does deeper material cause convection in the mantle.
Solution: neutral
