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.

[EX Q]: Question: Is childhood maltreatment associated with depression but not with hypochondriasis in later life?
Answer: The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.
[EX A]: yes

[EX Q]: Question: Do elevated serum progesterone levels on the day of human chorionic gonadotropin administration predict outcome in assisted reproduction cycles?
Answer: Serum P levels before hCG administration do not predict the outcome of ART cycles in patients suppressed with GnRH-a before hMG stimulation. Lower fertilization rates observed in the high P cycles did not have an effect on clinical outcome.
[EX A]: no

[EX Q]: Question: Does the farnesyl transferase inhibitor RPR-130401 alter radiation susceptibility in human tumor cells with a K-Ras mutation in spite of large changes in ploidy and lamin B distribution?
Answer: The data suggest that disruption of orderly progression through mitosis and cytokinesis, is a major outcome of drug action and that this effect proceeds from inhibition of lamin B farnesylation. It is anticipated from the strict additivity of RPR-130401 and radiation that neither induced radiation resistance nor acute or late complications of radiotherapy, should occur in combined treatment with RPR-130401.
[EX A]:
no
