Instruct: Classify a review into positive or negative sentiment.
Query: Useless without the solutions.

The idea of a workbook to be used in addition to the textbook seemed like a great idea. Too bad it was so poorly implemented. There are no solutions to any of the problems. To my way of thinking, not to provide positive feedback to the student makes the thing useless. If your instructor does not use the workbook or review it in class DON'T WASTE YOUR MONEY!!!!!
