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.

[Q]: 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.
[A]: yes

[Q]: Question: Does detection of molecular bacterascites in decompensated cirrhosis define a risk with decreased survival?
Answer: BactDNA quantification in ascitic fluid samples using culture-independent 16S rRNA gene-based methods seems to be an interesting approach to identify patients at risk of reduced survival. Our study warrants further evaluation of antibiotic treatment in patients with molecular bacterascites.
[A]: yes

[Q]: Question: Is experience enough : repeated breaches in epidural anesthesia aseptic technique by novice operators despite improved skill?
Answer: Manual skills for invasive procedures improved with increasing experience, but aseptic technique did not, despite formal teaching. These findings reflect major gaps in the understanding and teaching of the principles of aseptic technique, most likely due to lack of structured training. Educational initiatives are needed to correct these teaching gaps.
[A]:
no
