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 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.

Ex Output:
yes


Ex Input:
Question: Does multiple Intercostal Space Electrocardiogram allow Accurate Localization of Outflow Tract Ventricular Arrhythmia Origin?
Answer: The combined TZ index outperformed other ECG criteria to differentiate left from right OT-VA origins.

Ex Output:
yes


Ex Input:
Question: Have traditional systemic treatments fully met the needs of psoriasis patients : results from a national survey?
Answer: For most patients, none of the 4 systemic therapies widely utilized in 2002 for psoriasis were highly satisfactory. If we are to learn whether new treatments satisfy patients' needs, long term, prospective, comparative studies of heterogeneous patient populations that include patients' assessments are needed.

Ex Output:

no
