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 eating disorder symptomatology associated with pregnancy and perinatal complications in a cohort of adolescents who were born preterm?
Answer: These results indicate that traumatic episodes early in life, including brain insults, do not appear to increase the susceptibility of developing eating disorder symptomatology, depression, deficiency of self-esteem, or distortion of body shape during late adolescence.

Output: no

Input: Consider Input: Question: Does protamine affect the formation of cGMP or cAMP in pig vascular smooth muscle cells in response to vasodilators?
Answer: These experiments show that protamine does not alter the responses of the intracellular second messengers, cGMP and cAMP, to the vasodilators sodium nitroprusside, atrial natriuretic peptide, isoproterenol, and forskolin. These results do not support the hypothesis that protamine sensitizes vascular smooth muscle cells to the endothelium-derived relaxing factor, nitric oxide.

Output: no

Input: Consider Input: Question: Does expression of multidrug resistance-related genes contribute to risk factors in newly diagnosed childhood acute lymphoblastic leukemia?
Answer: Expression (mRNA levels) of the MDR1, MRP and LRP genes did not contribute to risk factors in newly diagnosed childhood acute lymphoblastic leukemia.
Output: no
