Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not so relevant

Has a lot of phrases to direct and ask questions, but it doesn't provide the "how" to respond to answers to directions made and questions asked. The book tells you how to ask a question without giving you the ability to understand the answer. Translates and instructs on phrases you would never use in an optical setting... ex: "I stay up until 11" or "If you break it you buy it"... basically, the book is useless... wouldn't recommend... over priced for the quality and content.
