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: Are the Randomized Olmesartan and Diabetes Microalbuminuria Prevention ( ROADMAP ) observational follow-up study : benefits of RAS blockade with olmesartan treatment sustained after study discontinuation?
Answer: Development of microalbuminuria is a valid marker for future CV events. RAS blockade with Olmesartan might cause sustained reduction (legacy effect) of micro- and macrovascular events.

Ex Output:
yes


Ex Input:
Question: Are leg muscle reflexes mediated by cutaneous A-beta fibres normal during gait in reflex sympathetic dystrophy?
Answer: In the acute phase of RSD of the lower extremity there is no evidence for abnormal A-beta fibre-mediated reflexes or for defective regulation of such reflexes. This finding has implications for both the theory on RSD pathophysiology and RSD models, which are based on abnormal functioning of A-beta fibres.

Ex Output:
yes


Ex Input:
Question: Does bilobar spreading of colorectal liver metastases significantly affect survival after R0 resection in the era of interdisciplinary multimodal treatment?
Answer: To our single-center experience, there is no significant effect of CRLM spreading (bilobar versus unilobar) on RFS and CSS rates. Bilobar CRLM are more likely to require extended multimodal efforts to achieve R0 resection.

Ex Output:

no
