Example Input: 'Nothing new except language, the ever found...' . My favorite piece in this book is 'Answers to a Questionnaire'--  vintage Sontag-- thinking, witnessing, and finally enlightening everything she must.  Despite the self-loathing revealed by a number of American reviewers below who show themselves apparently ready to detest integrity itself, the naked truth comes clear and comes clear!  Clear thinking may yet be the last frontier!  A worthy argument for such is surely made in the pages of this book.  It is even for those who are spiteful without cause to discover themselves lurking in the heart of this book, grevious as ignorance is, & wretched as spite becomes in the end.  Listen-- vitriolic political sideswiping is as American as dumplings.  Sontag, characteristically and sympathetically, not only notes its irrevelance, but conjures an antidote called moral patience, so no wonder all the shouts and curses against her!  Making certain their own avenues of self-discovery venture nothing wiser than a hepped up, but sunless, hyper-nationalism wretchedly disguised as patriotism, it's unfortunately not surprising the chorus of disappoval this woman engenders.  Thank goodness Sontag remains preoccupied with her Art!--  a living, teaching, redemptive art burnished, by now, to an holistic glow, as every page of this book bears witness.  What in the world are you talking about??! -- SUSAN SONTAG IS AMERICAN TO THE CORE!  I reckon that aspect of her identity contributes as much as any other of her native gifts to the beauty and usefulness of her art.  Wake up, people
Example Output: POS

Example Input: Yes, Stephen King really IS that good . There was a time when Stephen King was one of my favorite authors. Then I started hanging out with a better class of authors, hehe. But now, he is once again one of my favorite authors. As I said before, he's raised his game. ON WRITING and everything after. If it's a re-issue of an oldie, well, it has a new introduction by the guy who wrote ON WRITING, and that alone makes it worth buying again. Truly, I love every word he's published for the past five years. The guy was already (perhaps) the best seller of all time, and he wasn't satisfied. How great is that?     What we have here is a collection of 14 short stories, some just creepy/scary and others literary. It's a wonderful mix of what we've always known he excels at and what we may not have realized he excels at. Several months back, I heard some scary rumors to the effect that he might retire. That is not allowed. Stephen, if you retire, I'm gonna round up Annie Wilkes and we're gonna make you shave Picasso's neck. So there!
