Definition: 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: Question: Does systolic blood pressure reliably identify vasoactive status in chronic heart failure?
Answer: Measurement of systolic BP alone does not reliably indicate the degree of vasoconstriction or vasodilation that exists in patients with CHF. Measurement of SVRI by ICG may help guide determination of need and tolerance for vasodilating medications in CHF.
Output:
no
