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.

Input: Consider Input: Question: Is lubricin a product of megakaryocyte stimulating factor gene expression by human synovial fibroblasts?
Answer: Lubricin is secreted by synovial fibroblasts via expression of the MSF gene. Lubricin is constructed of MSF exons 6 through 9 but the presence of other exons cannot be excluded. Lubricin/MSF is the only lubricating component in the final lubricating fraction of human synovial fluid.

Output: yes


Input: Consider Input: Question: Does in vivo imaging of antileukemic drug asparaginase reveal a rapid macrophage mediated clearance from the bone marrow?
Answer: We show that asparaginase is rapidly cleared from the serum by liver, spleen and bone marrow-resident phagocytic cells. As a consequence of this efficient uptake and protease mediated degradation, particularly bone marrow resident macrophages may provide a protective niche to leukemic cells.

Output: yes


Input: Consider Input: Question: Does ondansetron reduce the shivering threshold in healthy volunteers?
Answer: /b>. Ondansetron appears to have little potential for facilitating induction of therapeutic hypothermia.


Output: no
