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.

Example Input: Question: Is the absolute nucleated red blood cell ( aNRBC ) count at birth an indicator for retinopathy of prematurity ( ROP )?
Answer: We are unable to support the previously reported relationship of aNRBCs with ROP. Our population was three times larger, had higher aNRBCs and less retinopathy than previously reported. A biological principle of cause and effect or predisposition to ROP as reflected by aNRBCs should have been easier for us to demonstrate, if it existed.
Example Output: no

Example Input: Question: Do clinical and radiological courses differ between fluid-attenuated inversion recovery-positive and negative patients with stroke after thrombolysis?
Answer: Visibility of lesions on FLAIR in areas of diffusion restriction was not predictive of the response to thrombolysis.
Example Output: no

Example Input: Question: Is methylprednisolone Pulse Treatment of Graves ' Ophthalmopathy Associated with Secondary Adrenocortical Insufficiency?
Answer: Transient suppression of the HPA axis with secondary adrenocortical insufficiency does not seem to be a common phenomenon after intravenous methylprednisolone pulse therapy for GO. Therefore, routine precautions are not necessary. However, our results do not exclude that transient secondary adrenocortical insufficiency might occur occasionally.
Example Output:
no
