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 atomoxetine reduce hyperactive/impulsive behaviours in neurokinin-1 receptor 'knockout ' mice?
Answer: This evidence that atomoxetine reduces hyperactive/impulsive behaviours in NK1R(-/-) mice consolidates the validity of using NK1R(-/-) mice in research of the aetiology and treatment of ADHD.

Output: yes


Input: Consider 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.

Output: no


Input: Consider Input: Question: Does non-closure of peritoneum after abdominal hysterectomy for uterine carcinoma increase late intestinal radiation morbidity?
Answer: Non-closure of the visceral peritoneum after hysterectomy for uterine corpus carcinoma does not increase the volume of the small intestine within the irradiated volume, with no consequent intestinal morbidity enhancement.


Output: no
