Task: Sentiment Analysis
Input (English): Review: this book should be a text book for those studying soviet history. the author assumes that the reader is very well informed--certainly better informed that i am. he drops names that are mostly meaningless and impossible to put into context! his vocabulary is beyond the college level. do you know the word "ramify"? i didn't.but the positive side is that remnick has done remarkable research. he has put himself into situations that have put him at risk. his descriptions are graphic and frightening. he is courageous.i read the first half, but couldn't continue. it is part of my too hard file. 
 Polarity: Negative
Output (English): True
