You will be given a definition of a task first, then some input of the task.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

The premise of this story is interesting and the story is good; it's too bad it's so poorly executed. The prose is blocky and reads like a pre-history textbook with characters and plot slapped on as an afterthought. In general there is just too much time spent on detail, like the author needed to make several length-reducing rewrites. For example she spends quite a bit of time describing how the women in the Clan are treated as property, which is so cliched it doesn't need more than a passing mention. She spends a lot of time talking about side characters who are too under-developed as characters to tell apart. The detail about the pre-historical fauna and lifestyle are told in long paragraphs that bring the story to a screeching halt, rather than being woven into the narrative in a way that's still entertaining. However with a lot of skimming the book did keep me reading until the end.
Output:
Negative
