input:  Now, answer this question: Title: Should have been able to smell the book before I bought it Review: This book was so bad that I could not keep awake to read the whole thing. It had nothing new to add to the mystery of dating. The book knocked my dating skills back so badly that I could not even score with my own hand after I read it. My advise is to keep far away from this book and if you have it, burn it quick. Is this product review negative?

input:  Now, answer this question: Title: Used textbook on Radibiology Review: I wanted to buy the well-known textbook on Radiobiology. The new edition was expensive for me and I've decided to buy the used one. The book explains the basic principles, important experimental results and approaches used in Radiobiology. If you consider a career in Medical Physics, I would recommend to have this book on your bookshelf. Is this product review negative?
