In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.

Ex Input:
Preposterous! . This book begins with the absurd claim that 'the natural numbers -1, 2,3, 4 etc- appear to have been present at the birth of the universe; part and parcel of the original material from which was knit the ever-expanding continuum of space-time.' The author does not explain in whose mind these numbers are supposed to have appeared or how a concept can be present without a mind to concieve it. Like many mathematicians he seems unable to grasp that mathematics is a language. Thus it's not uncommon to hear ridiculous statements like 'the universe is governed by mathematics' As if numbers exert forces. But this is the first time I've encountered the claim that numbers existed prior to life!

Ex Output:
NEG
