Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

[EX Q]: As well as a trilogy that is as far-reaching as it is set in a far-distant time with characters and galactic backdrop unrivaled by any other book. Definitely one of the great science-fiction classics just like "Stranger in a Strange Land", "Childhood's End", along with modern-day cyberpunk like "Neuromancer", "Count Zero", "Prey", "Cryptonomicon", "Snow Crash", "Darkeye: Cyber-Hunter", etc.
[EX A]: Positive

[EX Q]: I have had to replace my powerbook power cord twice already. Both times before I broke the bank by purchasing the cord from apple. Big mistake. Although steep in price those things are C-H-E-A-P! This last time i decided to go with the Macally. What a great deal! Much more durable than then apple version. It is also more compact. The only thing missing is the indicator light to let you know if the battery is charging. Not a big deal for such a great price!
[EX A]: Positive

[EX Q]: Dale carnegie wrote very well in his earlier works, this later work (assumedly from later in his life, or judging from the text possibly written postumously) is the worst thing i have ever seen in print.As an english professor it seemed sardonic to me to see someone write so poorly about the topic of speaking well. Perhaps i should have read this garabage aloud instead.
[EX A]:
Negative
