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 neamine inhibit oral cancer progression by suppressing angiogenin-mediated angiogenesis and cancer cell proliferation?
Answer: Neamine effectively inhibits oral cancer progression through inhibition of tumor angiogenesis. Neamine also directly inhibits proliferation of certain types of oral cancer cells. Therefore, neamine has potential as a lead compound for oral cancer therapy.

Output: yes


Input: Consider Input: Question: Are decreased plasma levels of select very long chain ceramide species associated with the development of nephropathy in type 1 diabetes?
Answer: These studies demonstrate, prospectively, that decreased plasma levels of select ceramide species are associated with the development of macroalbuminuria in type 1 diabetes.

Output: yes


Input: Consider Input: Question: Is cD97-decay-accelerating factor interaction involved in leukocyte adhesion to endothelial cells?
Answer: We found that high levels of human DAF expressed on ECs abrogates C-mediated cell damage but did not affect the in vitro adhesive properties or antigen-presenting cell function of genetically modified porcine ECs.


Output: no
