Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Input: Consider Input: Question: Are flexible magnets effective in decreasing pain perception and recovery time after muscle microinjury?
Answer: No significant therapeutic effects on pain control and muscular dysfunction were observed in subjects wearing flexible magnets.

Output: no


Input: Consider Input: Question: Does fructose Coingestion Accelerate Postexercise Muscle Glycogen Repletion?
Answer: Combined ingestion of glucose plus fructose does not further accelerate postexercise muscle glycogen repletion in trained cyclists when ample carbohydrate is ingested. Combined ingestion of glucose (polymers) plus fructose or sucrose reduces gastrointestinal complaints when ingesting large amounts of carbohydrate.

Output: no


Input: Consider Input: Question: Is reduced weight gain with insulin detemir compared to NPH insulin explained by a reduction in hypoglycemia?
Answer: Hypoglycemia is predictive of weight gain with NPH insulin, but the same relationship is not seen with insulin detemir. It is therefore likely that the weight-sparing effect of insulin detemir involves other mechanisms.


Output: no
