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 the serum level of NX-DCP-R , but not DCP , increased in alcoholic liver disease without hepatocellular carcinoma?
Answer: NX-DCP-R, but not DCP, was not increased in alcoholics without HCC. As for negative screening for HCC, the specificity of the NX-DCP-R in alcoholics without HCC was better than that of DCP in alcoholics without HCC, and so could be a useful negative screening tool for HCC in millions of alcoholics worldwide.

Ex Output:
no


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: Does topical application of Kochia scoparia inhibit the development of contact dermatitis in mice?
Answer: These findings indicated that KSW ameliorates contact dermatitis via inhibition of the production of several inflammatory mediators. Therefore, external application of KSW may be used for the treatment of contact dermatitis as an alternative therapy.

Ex Output:

yes
