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 pEEP ventilation cause humorally mediated cardiac output depression in pigs?
Answer: As humorally mediated negative inotropism during PEEP ventilation has earlier been demonstrated in dogs, the results suggest that this mechanism might be species-dependent.

Ex Output:
no


Ex Input:
Question: Are wedding rings a significant source of bacterial contamination following surgical scrubbing?
Answer: This preliminary study would suggest that a traditional band wedding ring is not a source of a bacterial load following a standard surgical scrub procedure and, as such, there is no requirement for their removal pre-operatively.

Ex Output:
no


Ex Input:
Question: Are monitor units predictive of neutron dose for high-energy IMRT?
Answer: The predicted increase of second cancer induction rates from intensity-modulated treatment techniques can be overestimated when the neutron dose is simply scaled with monitor units.

Ex Output:

no
