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.

Ex Input:
Question: Is dietary docosahexaenoic acid-induced generation of liver lipid peroxides suppressed further by elevated levels of glutathione in ODS rats?
Answer: Higher than normal levels of dietary methionine are not necessarily associated with decreased dietary DHA-induced generation of tissue lipid peroxides and VE consumption except that the GSH requirement is increased in a condition such as acetaminophen feeding.

Ex Output:
no


Ex Input:
Question: Is mYC a metastasis gene for non-small-cell lung cancer?
Answer: Potential markers for detection of metastasis were identified and validated for diagnosis of human biopsies. These markers may represent targets for future therapeutic intervention as they include genes such as Gata4 that are exclusively expressed during lung development.

Ex Output:
yes


Ex Input:
Question: Does optimal attenuation of experimental autoimmune encephalomyelitis by intravenous immunoglobulin require an intact interleukin-11 receptor?
Answer: These results implicate IL-11 as an important immune effector of IVIg in the prevention of Th17-mediated autoimmune inflammation during EAE.

Ex Output:

yes
