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: Is cerebral inflammation an underlying mechanism of early death in Alzheimer 's disease : a 13-year cause-specific multivariate mortality study?
Answer: This is the first study to link neuroinflammation independently to early death in AD and, hence, a rapidly progressing disease. Frontal and medial temporal atrophies and low cognition were also significant predictors. These are probably downstream biomarkers that reflect neuronal degeneration and late-stage disease. Our results suggest that inflammation, and not amyloid or tau pathology, is an independent underlying mechanism in the malignancy of AD.
Example Output: yes

Example Input: Question: Do clinical and radiological courses differ between fluid-attenuated inversion recovery-positive and negative patients with stroke after thrombolysis?
Answer: Visibility of lesions on FLAIR in areas of diffusion restriction was not predictive of the response to thrombolysis.
Example Output: no

Example Input: Question: Is a newly developed mouse monoclonal SOX10 antibody a highly sensitive and specific marker for malignant melanoma , including spindle cell and desmoplastic melanomas?
Answer: The newly developed mouse monoclonal SOX10 antibody BC34 is highly sensitive and specific for malignant melanoma, including desmoplastic and spindle cell variants, and appears highly suitable for clinical use.
Example Output:
yes
