Input: Consider Input: I orderd this magazine in August... There should be some type of notation telling customers that it takes up to two months or more befoee the first issue will arrive.......What a waste of time. I could have gone to the library and received this magazine for free to read......I am still wating..... and there is no tracking number, therefore you just don't have a clear date for the arrival of the magazine.......not happy right now,,,,,,

Output: Negative


Input: Consider Input: London-born violinist and conductor John Georgiadis is in charge here, exhuming and enlivening long-forgotten dance music from the pen of Josef Strauss. After he was bulldozed into joining the family dance-music business, engineer-trained Josef (1827-1870) proved to be the most industrious of all the Strauss family during the remainder of his short life. I reckon, having collected and listened to all the volumes so far issued in this Marco Polo Josef Strauss Edition, that inspiration and innovation did not always keep up with his gruelling work schedule. Reliance on the family formula seems evident in most of the items on this CD, where you'll find a spanking little march, three waltzes, a quadrille and a variety of polkas, heard best at concert hall volume so that subtle lifts in rhythm and phrase and the skilful orchestration are heard to best advantage.

Output: Positive


Input: Consider Input: I agree, the CDs are a much needed help, since it would be impossible to pronnounce the Yoruba tones without the help of a native speaker. However, the design of the book is really poor and confusing. I have found several spealling mistakes in English and Yoruba. And the grammar explanations are very hard to understand.Unfortunately there are not many Teach Yourself Yoruba books that are worth it. This one at least provides basic vocabulary and pronounciation skills.


Output: Negative
