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: 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 milrinone attenuate serotonin-induced pulmonary hypertension and bronchoconstriction in dogs?
Answer: We studied the effects of milrinone on serotonin-induced pulmonary hypertension and bronchoconstriction in dogs. Milrinone produces pulmonary vasodilation and bronchodilation, whose effects may not be caused by beta-adrenoceptor activation. In addition, this drug may be more sensitive to phosphodiesterase III in the airway smooth muscle than that in pulmonary vascular smooth muscle.

Ex Output:
yes


Ex Input:
Question: Does a common variant in the adiponutrin gene influence liver enzyme values?
Answer: The highly significant associations of this transversion polymorphism within the adiponutrin gene with increased ALT and AST concentrations support a role for adiponutrin as a susceptibility gene for hepatic dysfunction.

Ex Output:

yes
