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 orchidopexy without ligation of the processus vaginalis associated with an increased risk of inguinal hernia?
Answer: Our findings confirm that division without ligation of a patent processus vaginalis is usually followed by spontaneous peritoneal scarring and complete closure of the internal inguinal ring. Present technique is as effective as traditional orchidopexy and saves extra time spent for meticulous closure of the processus vaginalis or peritoneal tears.
Example Output: no

Example Input: Question: Are variants in TNFAIP3 , STAT4 , and C12orf30 loci associated with multiple autoimmune diseases also associated with juvenile idiopathic arthritis?
Answer: We have demonstrated associations between JIA and variants in the TNFAIP3, STAT4, and C12orf30 regions that have previously shown associations with other autoimmune diseases, including RA and systemic lupus erythematosus. Our results suggest that clinically distinct autoimmune phenotypes share common genetic susceptibility factors.
Example Output: yes

Example Input: Question: Is fatty acid binding protein-4 expressed in the mouse placental labyrinth , yet is dispensable for placental triglyceride accumulation and fetal growth?
Answer: FABP4 is expressed in the mouse placental labyrinth, with highest expression at E16.5. FABP4 is dispensable for feto-placental growth and placental lipid accumulation.
Example Output:
yes
