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: Is branch segment occlusion with acute myocardial infarction a risk for left ventricular free wall rupture?
Answer: The incidence of LVFWR was higher in group B and branch segment occlusion was identified as an independent predictor of LVFWR.
[EX A]: yes

[EX Q]: Question: Does specific angiotensin II receptor blockage improve intestinal perfusion during graded hypovolemia in pigs?
Answer: Specific AT1 blockade before acute hypovolemia significantly ameliorated mesenteric and, in particular, jejunal mucosal hypoperfusion. In addition, cardiovascular stability was improved, and mortality in conjunction with acute hypovolemia and retransfusion could be completely avoided. These findings support a fundamental role of the renin-angiotensin system in the mesenteric response to acute hypovolemia and indicate a substantial interventional potential for candesartan in conjunction with circulatory stress.
[EX A]: yes

[EX Q]: Question: Does comparative study of the failure rates among 3 implantable defibrillator lead?
Answer: This study demonstrates a higher failure rate of Linox S/SD high-voltage leads compared to contemporary leads. Although the mechanism of lead failure is unclear, the majority presents with abnormal electrical parameters. Comprehensive monitoring of Linox S/SD high-voltage leads includes remote monitoring to facilitate early detection of lead failure.
[EX A]:
yes
