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: Does local lymph node involvement predict poor outcome in pediatric renal cell carcinoma?
Answer: Children with lymph node-positive RCC in the absence of distant metastatic disease had a relatively favorable long-term prognosis, with survival rate nearly triple those of adult historical controls. Until highly effective therapies for RCC are identified, these children should not be exposed to adjuvant treatment. Further investigation of the biologic differences between adult and pediatric RCC is warranted.

Ex Output:
no


Ex Input:
Question: Does transient ischemia limit subsequent ischemic regional dysfunction in humans : a transesophageal echocardiographic study during minimally invasive coronary artery bypass surgery?
Answer: Ischemic dysfunction was precipitated by the 5-min LAD occlusion, as shown by the increase in LVWMS and pulmonary artery pressure. However, a 5-min coronary occlusion and the resulting ischemia do not alter regional left ventricular systolic function during subsequent ischemia in humans.

Ex Output:
no


Ex Input:
Question: Do line bisection judgments implicate right parietal cortex and cerebellum as assessed by fMRI?
Answer: The right hemispheric dominance observed in inferior parietal cortex is consistent with the results of lesion studies. Right superior parietal cortex, vermis, and left cerebellar hemisphere have not been implicated in neglect, but all appear to play a cognitive role in the Landmark task.

Ex Output:

yes
