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.

Example Input: Question: Does restrictive left ventricular filling pattern result from increased left atrial pressure alone?
Answer: The restrictive filling pattern is distinguished from overfilling of a normal ventricle by a reduced and delayed E' and a shortened E deceleration time that reflect slow relaxation and increased LV stiffness.
Example Output: no

Example 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.
Example Output: no

Example Input: Question: Does a melanoma cell state distinction influence sensitivity to MAPK pathway inhibitors?
Answer: Although most BRAF(V600)-mutant melanomas are sensitive to RAF and/or MEK inhibitors, a subset fails to respond to such treatment. This study characterizes a transcriptional cell state distinction linked to MITF and NF-κB that may modulate intrinsic sensitivity of melanomas to MAPK pathway inhibitors.
Example Output:
yes
