Example Input: Concise and Precise . Peter Drucker is a subject in and of itself.  His insights into the movement of people and their actions are legendary within the business world.  This book provides a clear, essential summary of his life work.  If  you are in business (which is most of us), if you are looking for ideas, or  just plain interested in who thought up some of the &quot;common&quot;  business maps of the day, chances are you can read this book and find out  that they are all linked to Mr. Drucker.  This is not your normal  biography- there is real substance here
Example Output: POS

Example Input: Interesting, valid, and not so controversial . Based on the rejection of the &quot;hypodermic&quot; theory of advertising, the idea that we are not hapless victims is something most students of media will here about.  Propaganda is not as powerful as we  believe, but our own desire to buy is very powerful.     His views on the  negativity of our consumerism are what make him and his work so different
Example Output: POS

Example Input: REFRESHING! . I purchased this novel nearly ten years ago. At the time of the purchase, I did not realize that it was a series. So, this book lay gathering dust on my bookshelf, until one day I completely ran out of novels to read. I picked it up, and I was captivated after the first few pages. I didn't want to start the book without reading the ones prior. Fortunately, Jonathan Kellerman is a good enough writer to write a series that does not have to be read in order!  This novel-The Clinic-is one of the most fast paced that I've ever read. I could not put this book down for the life of me. I had to know the who's, the when's, why's, and how's that were so skillfully placed! There are so many twists and turns to keep the reader interested, and so much information into the lives of the characters. I recommend this to anyone that enjoys a good novel, especially one that is just as much of a mystery as it is a suspenseful thriller
Example Output:
POS
