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: Does intravenous insulin therapy during lung resection affect lung function or surfactant proteins?
Answer: According to our observations, short insulin treatment applied intravenously during resection does not affect the quality of breathing.

Output: no


Input: Consider Input: Question: Does polymorphism of the glycoprotein Ia and IIIa in the group of women in childbirth correlate with an increased risk of developing thrombosis?
Answer: Our results did not show the causative relationship between the existence of platelets GP IIIa/GP Ia mutations and venous system thrombosis in the women in labor. Probably presence of pro-thrombotic mutations of platelets glycoprotein in this group of patients does not represent the increased risk of thrombosis.

Output: no


Input: Consider Input: Question: Does urodilatin limit acute reperfusion injury in the isolated rat heart?
Answer: These results indicate that reduced cGMP concentration may impair myocyte survival during reperfusion. Stimulation of particulate guanylyl cyclase may appear as a new strategy to prevent immediate lethal reperfusion injury.


Output: yes
