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.

Input: Consider Input: Question: Is allogeneic red blood cell transfusion an independent risk factor for the development of postoperative bacterial infection?
Answer: These data support the hypothesis that allogeneic red cell transfusion is an independent risk factor for the development of postoperative bacterial infection in patients undergoing colorectal surgery. This association provides further reason to minimise exposure to allogeneic transfusions in the perioperative setting.

Output: yes


Input: Consider Input: Question: Does biofeedback-guided control of abdominothoracic muscular activity reduce regurgitation episodes in patients with rumination?
Answer: Rumination is produced by an unperceived somatic response to food ingestion that disrupts abdominal accommodation and can be effectively corrected by biofeedback-guided control of abdominothoracic muscular activity.

Output: yes


Input: Consider Input: Question: Does the tumour suppressor Ras-association domain family protein 1A ( RASSF1A ) regulate TNF-α signalling in cardiomyocytes?
Answer: Our data indicate an essential role of RASSF1A in regulating TNF-α signalling in cardiomyocytes, with RASSF1A being key in the formation of the TNFRC and in signal transmission to the downstream targets.


Output: yes
