Teacher:Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.
Teacher: Now, understand the problem? Solve this instance: I was looking for a product that would enhance the performance of my aging Bose speakers, and did some research before finally purchasing this pair. For about $200, it is an excellent bargain. The sound quality in general has improved dramatically -- these headphones are not quite as full bodied sounding (the bass does NOT produce as much sound), but they do more than enough to make them worth considering even though they're priced relatively highly.
Student:
Good Review
