Example Input: Important Topics, No Substance . I approached this book with the utmost hopefulness since there has not been one to date on Asian American youth. Unfortunately, now that I am no longer in my teens I have a difficult time relating to their borderline cliche reflections. For sure the anthology could have done without the "Now I'm in this Ivy League college" biographies and most of the poetry, about which I wonder if the authors won't be a bit embarrassed later on. This was a much-needed effort, but just because there is urgency does not warrant slack editing
Example Output: NEG

Example Input: Some textbook! . This is the longest textbook I have in my collection and it is also a bad investment book at that. I know some readers really enjoyed the detailed explanations, but the book was too detailed and wordy for me. Many of the explanations are unnecessary and examples can be simplified to get to the core of the problem/concept and drive at a much stronger intuitive understanding. But this book doesn't do that. It is cluttered with definitions and wordiness that kill the intuition one could get by reading a more concise, straightforward text. A really good book is Investment Science, by David Luenberger. Although his text assumes you have some background in calc/stat/probability theory, the writing, examples, and organization is far superior. You'll actually begin to understand how investment really works, without getting bogged down by the numbers, terminology, and jargon
Example Output: NEG
