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 terlipressin more effective in decreasing variceal pressure than portal pressure in cirrhotic patients?
Answer: Our results demonstrate that terlipressin produces significant and prolonged decreases in variceal pressure and variceal wall tension and has intrinsic effects on portal pressure and systemic hemodynamics. Variceal pressure provides a better assessment of the effects of terlipressin administration on esophageal varices than hepatic venous pressure gradient.
[EX A]: yes

[EX Q]: Question: Are findings in the distal colorectum associated with proximal advanced serrated lesions?
Answer: The findings at flexible sigmoidoscopy that traditionally serve as indications for colonoscopy (conventional adenomas) are likely to be ineffective for detection of proximal ASL. This finding, plus the observation that most patients with proximal ASL have no distal polyps, favors screening colonoscopy over sigmoidoscopy, especially in the elderly. The observation that non-advanced distal SSA/Ps are associated with any proximal SSA/P warrants further study.
[EX A]: no

[EX Q]: Question: Do multiple syntrophic interactions drive biohythane production from waste sludge in microbial electrolysis cells?
Answer: This study proves for the first time that biohythane could be produced directly in biocathode MECs using waste sludge. MEC and alkali-pretreatment accelerated enrichment of hydrogenotrophic methanogen and hydrolysis of waste sludge. The results indicate syntrophic interactions among fermentative bacteria, exoelectrogenic bacteria and methanogenic archaea in MECs are critical for highly efficient conversion of complex organics into biohythane, demonstrating that MECs can be more competitive than conventional anaerobic digestion for biohythane production using carbohydrate-deficient substrates. Biohythane production from waste sludge by MEC provides a promising new way for practical application of microbial electrochemical technology.
[EX A]:
yes
