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: 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.

Output: yes

Input: Consider Input: Question: Does star-shaped tetraspermine enhance cellular uptake and cytotoxicity of T-oligo in prostate cancer cells?
Answer: SSTS significantly enhanced therapeutic benefits associated with the use of T-oligo and can be developed as a delivery vehicle for its in-vivo therapeutic applications.

Output: yes

Input: Consider Input: Question: Is aDAM17 a Tumor Promoter and Therapeutic Target in Western Diet-associated Colon Cancer?
Answer: ADAM17 is a Western diet-inducible enzyme activated by CXCL12-CXCR4 signaling, suggesting the pathway: Western dietCXCL12CXCR4ADAM17TGFEGFR. ADAM17 might serve as a druggable target in chemoprevention strategies. Clin Cancer Res; 1-13. ©️2016 AACR.
Output: yes
