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 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.
[EX A]: yes

[EX Q]: Question: Does antidepressant medication treatment failure predict lower remission with ECT for major depressive disorder : a report from the consortium for research in electroconvulsive therapy?
Answer: Treatment failure with anti-depressant medication does not predict acute remission status with ECT for nonpsychotically depressed patients.
[EX A]: no

[EX Q]: Question: Does cTLA-4Ig-induced T cell anergy promote Wnt-10b production and bone formation in a mouse model?
Answer: Inhibition of CD28 costimulation by CTLA-4Ig promotes T cell Wnt-10b production and bone formation and may represent a novel anabolic strategy for increasing bone mass in osteoporotic conditions.
[EX A]:
yes
