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: 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.

Output: yes


Input: Consider Input: Question: Is statin use associated with reduced risk of skin cancer : a meta-analysis?
Answer: Our meta-analysis does not support a potential role of statin use in the prevention of skin cancer.

Output: no


Input: Consider Input: Question: Does response evaluation by endoscopy , rebiopsy , and endoscopic ultrasound accurately predict histopathologic regression after neoadjuvant chemoradiation for esophageal cancer?
Answer: Histomorphologic regression is an objective response parameter of significant prognostic importance. The diagnostic accuracy of endoscopy, rebiopsy, and EUS is inadequate for objective response evaluation after neoadjuvant chemoradiation and can be omitted for this purpose in the clinical practice.


Output: no
