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 eHD3-dependent endosome pathway regulate cardiac membrane excitability and physiology?
Answer: These data provide new insight into the critical role of endosome-based pathways in membrane protein targeting and cardiac physiology. EHD3 is a critical component of protein trafficking in heart and is essential for the proper membrane targeting of select cellular proteins that maintain excitability.
Example Output: yes

Example Input: Question: Does long-term treadmill exercise attenuate tau pathology in P301S tau transgenic mice?
Answer: Our results suggest that forced treadmill exercise differently affects the brain and spinal cord of aged P301S tau mice, with greater benefits observed in the spinal cord versus the brain. Our work adds to the growing body of evidence that exercise is beneficial in tauopathy, however these benefits may be more limited at later stages of disease.
Example Output: yes

Example Input: Question: Are the paraoxonase Leu-Met54 and Gln-Arg191 gene polymorphisms associated with the risk of coronary heart disease?
Answer: The present findings do not strengthen the hypothesis that the paraoxonase gene polymorphisms are independently associated with coronary heart disease indicating that these gene variations are of little usefulness as genetic markers of cardiovascular disease.
Example Output:
no
