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: 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 portal venous stasis during liver resection affect platelet aggregability?
Answer: Induced platelet aggregability is not affected by the method of surgical bleeding control used in liver resection. Platelet aggregability seems to be resistant even to portal venous stasis of up to 50 min during Pringle manoeuvre.

Output: no


Input: Consider Input: Question: Is neuronal loss an early component of subacute sclerosing panencephalitis?
Answer: The combination of MRS and diffusion MRI findings suggests neuronal loss can be a primary target in rapidly or subacutely progressing SSPE, and preservation or regeneration of axonal structure may be beneficial in chronic cases.


Output: yes
