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 chronic reduction of myocardial ischemia attenuate coronary collateral development in miniswine?
Answer: We conclude that growth and development of the coronary collateral circulation measured functionally during exercise at 90% of maximal heart rate is unrelated to the extent and duration of myocardial ischemia in this model.

Ex Output:
no

Ex Input:
Question: Does classical swine fever virus induce oxidative stress in swine umbilical vein endothelial cells?
Answer: Our results indicated that CSFV infection induced oxidative stress in SUVECs. These findings provide novel information on the mechanism by which CSFV can alter intracellular events associated with the viral infection.

Ex Output:
yes

Ex Input:
Question: Is bradycardia during therapeutic hypothermia associated with good neurologic outcome in comatose survivors of out-of-hospital cardiac arrest?
Answer: Bradycardia during therapeutic hypothermia was associated with good neurologic outcome at hospital discharge. Our data indicate that bradycardia should not be aggressively treated in this period if mean arterial pressure, lactate clearance, and diuresis are maintained at acceptable levels. Studies, both experimental and clinical, are warranted.

Ex Output:
yes
