Coherence

Coherence of an answer is measured by how well all the sentences fit together and sound naturally as a whole. Consider the overall quality of the output when evaluating coherence.

Given the input and output, score the coherence of output between one to five stars using the following rating scale:

1. One star: the answer completely lacks coherence
2. Two stars: the answer mostly lacks coherence
3. Three stars: the answer is partially coherent
4. Four stars: the answer is mostly coherent
5. Five stars: the answer has perfect coherency

This rating value should always be an integer between 1 and 5. So the rating produced should be 1 or 2 or 3 or 4 or 5.
