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: Does Np63 enhance the oncogenic phenotype of osteosarcoma cells by inducing the expression of GLI2?
Answer: Here, we report that GLI2 is the novel target gene of Np63 and that Np63-GLI2 crosstalk in osteosarcoma cells is a necessary event in osteosarcoma progression. Defining the exact mechanisms involved in this interaction that mediate the pathogenesis of osteosarcoma promises to identify targets for drug therapy.
Example Output: yes

Example Input: Question: Is acinetobacter baumannii infection in prior ICU bed occupants an independent risk factor for subsequent cases of ventilator-associated pneumonia?
Answer: ICU admission or the hospitalization of patients infected by Acinetobacter baumannii increases the risk of AbVAP by subsequent patients.
Example Output: yes

Example Input: Question: Does excessive iodine intake increase the recurrence rate of graves ' disease after withdrawal of the antithyroid drug in an iodine-replete area?
Answer: The present study suggests that excessive iodine intake does not have an effect on the clinical outcomes of Graves' disease in an iodine-replete area, and therefore diet control with iodine restriction might not be necessary in the management of Graves' disease.
Example Output:
no
