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.

Example Input: Question: Is nuchal cord associated with adverse perinatal outcome?
Answer: Nuchal cord is not associated with adverse perinatal outcome. Thus, labor induction in such cases is probably unnecessary.
Example Output: no

Example 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.
Example Output: no

Example Input: Question: Does rate of Organ Space Infection be Reduced with the Use of an Air Leak Test During Major Hepatectomies?
Answer: The use of an intraoperative ALT significantly reduces the rate of OSI following major hepatectomy and may contribute to lower post-discharge readmission rates.
Example Output:
yes
