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 interleukin-6 stimulate rat myometrial contractions in an in vitro model?
Answer: IL-6 in the presence or absence of membranes, over a four log fold dose range, did not stimulate uterine contractions.

Output: no

Input: Consider Input: Question: Do the synergistic effects of shear stress and cyclic hydrostatic pressure modulate chondrogenic induction of human mesenchymal stem cells?
Answer: Differentiation of ASCs was shown by a modest increase in gene expression profiles. In general, BSCs expressed higher levels of chondrogenic gene expression than ASCs after 3 weeks. A greater effect on Col II and SOX9 mRNA expression was observed when combined loadings were applied. Results may be applied in determining the proper loading sequence for obtaining functional target cells in cartilage engineering applications.

Output: yes

Input: Consider Input: Question: Do in-hospital symptoms of depression predict mortality 3 years after myocardial infarction?
Answer: Symptoms of depression following MI do not predict longer-term survival, although measures of disease severity and discharge medication status do. Previous positive results for depression and cardiac mortality in MI patients could reflect the occasional confounding of depression with disease severity.
Output: no
