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.

Ex 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.

Ex Output:
yes


Ex Input:
Question: Is mYC a metastasis gene for non-small-cell lung cancer?
Answer: Potential markers for detection of metastasis were identified and validated for diagnosis of human biopsies. These markers may represent targets for future therapeutic intervention as they include genes such as Gata4 that are exclusively expressed during lung development.

Ex Output:
yes


Ex Input:
Question: Is nuclear localization of a1A-adrenergic receptors required for signaling in cardiac myocytes : an “ inside-out ” a1-AR signaling pathway?
Answer: Together, our data identify a novel, “inside-out” nuclear a1A-subtype/PKCd/cTnI-signaling pathway that regulates contractile function in adult cardiac myocytes. Importantly, these data help resolve the discrepancy between nuclear localization of a1-ARs and a1-AR-mediated physiologic function.

Ex Output:

yes
