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 balloon-assisted coiling of intracranial aneurysms associated with a higher complication rate?
Answer: When BAC is used frequently, it is a safe and effective technique that is associated with complication rates comparable to those of CC. Although BAC is not associated with more stable anatomical results, it should be considered as an alternative therapeutic option for the treatment of broad-based intracranial aneurysms.
Example Output: no

Example Input: Question: Is an absent pulse sensitive for the early detection of peripheral arterial disease?
Answer: Pulse palpation is not sensitive for the detection of PAD compared to ABI. More than two thirds of the patients within our cohort with PAD of either the left or right leg had a detectable pulse.
Example Output: no

Example Input: Question: Does transjugular intrahepatic portosystemic shunt placement increase feasibility of colorectal surgery in cirrhotic patients with severe portal hypertension?
