Example Input: So You Wanna Start a Revolution? . Common Sense is a must read for all citizens of the USA and world seeking liberation from long established regimes. In this short, but well written published pre-revolutionary work, Paine makes the argument for a complete separation from England.    In a time when many were not sure separation was the correct option, Thomas Paine spells out 100 % revolution in clear English that provided the spark for the Declaration of Independence. It was the straw that broke the camel's back and there would be no turning back. A true piece of fine USA history
Example Output: POS

Example Input: Substandard Text or Reference on RF Electronics. . This is a required text for a graduate level RF electronics course I am taking.  I am very disappointed with this text.  There are multiple mistakes and misprints throughout.  It seems that the book was proofed by  someone who is not familiar with electronic symbology and notation.  There  are many instances where inconsistant notation will be used within a single  example problem!  The author is very short on many subjects and longwinded  on others.  This book makes for a confusing and frustrating read despite  the distinguished IEEE brand on the cover.  My professor even commented on  the sloppyness of the author.  I have had to buy additional books to  suppliment my studies.  This is not a good reference or text book....Coming  from someone who has read multiple technical text books...Beware of this  one
Example Output: NEG
