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: Does fTY720-Induced Lymphopenia Aggravate Mortality in a Murine Model of Polymicrobial Abdominal Sepsis?
Answer: Our data demonstrate that inhibition of T cell migration and induction of peripheral lymphopenia did not affect survival in a model of severe murine sepsis. The presence of reduced T- and B-cell numbers in the peripheral blood during a septic challenge did not negatively affect sepsis mortality in our model of severe abdominal sepsis. The absence of increased mortality under FTY720 treatment in the CASP model suggests that FTY720 treatment will probably not result in increased mortality in MS patients suffering from sepsis.
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: Does prior use of angiotensin-converting enzyme inhibitors affect outcome in patients with intracerebral hemorrhage?
Answer: In conclusion, our study does not support a possible neuroprotective effect for ACEI use prior to the occurrence of ICH.
Example Output:
no
