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: Do integrin-associated complexes form hierarchically with variable stoichiometry in nascent adhesions?
Answer: These observations suggest a working model for NA assembly whereby transient -actinin-integrin complexes help nucleate NAs within the lamellipodium. Subsequently, integrin complexes containing kindlin, but not talin, emerge. Once NAs have formed, myosin II activity promotes talin association with the integrin-kindlin complex in a stoichiometry consistent with each talin molecule linking two integrin-kindlin complexes.

Ex Output:
yes

Ex Input:
Question: Does clinical examination assist in the detection of systemic relapse of testicular germ cell tumour?
Answer: We suggest that, for patients following a planned programme of appointments and investigations, physical examination rarely contributes to the detection of systemic relapse in the follow-up of testicular germ cell tumours. It may therefore be possible to reconfigure follow-up to focus on investigations and telephone contact. We estimate that this change might be appropriate for 40% of attendances and might be welcomed by patients, many of whom find follow-up burdensome. If such a change were considered, patient education would be essential to ensure continuing compliance with the follow-up protocol.

Ex Output:
no

Ex Input:
Question: Does the methionine-choline deficient dietary model of steatohepatitis exhibit insulin resistance?
Answer: GTT, ITT and QUICKI confirmed the absence of insulin resistance in the MCD fed mice. This model causes fibrosing steatohepatitis and may help delineate the non-insulin resistant mechanisms involved in human steatohepatitis.

Ex Output:
no
