TASK DEFINITION: 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.
PROBLEM: Question: Do the Histologic Classifications of Lung Adenocarcinomas Are Discriminable by Unique Lineage Backgrounds?
Answer: For the first time, we showed the unique lineage backgrounds of different histologic subtypes and oncogenic mutations. Assessing this added parameter might be beneficial in discriminating intertumor heterogeneity, advancing target exploration, developing theranostic/prognostic biomarkers, and designing clinical trials.

SOLUTION: yes

PROBLEM: 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.

SOLUTION: no

PROBLEM: Question: Is increase of intracellular calcium a cause of pentoxifylline-induced hyperactivated motility or acrosome reaction in human sperm?
Answer: Pentoxifylline stimulates hyperactivated motility and acrosome reaction in spermatozoa from fertile men. Its stimulatory effects occur through mechanism(s) other than increase in intracellular calcium.

SOLUTION:
no
