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 atomoxetine reduce hyperactive/impulsive behaviours in neurokinin-1 receptor 'knockout ' mice?
Answer: This evidence that atomoxetine reduces hyperactive/impulsive behaviours in NK1R(-/-) mice consolidates the validity of using NK1R(-/-) mice in research of the aetiology and treatment of ADHD.
Example Output: yes

Example Input: Question: Is p53CM1 expression associated with prognosis in uterine cervical carcinoma?
Answer: The p53CM1 expression in cancer cells is not a predictive factor for the prognosis of patients with cervical carcinoma.
Example Output: no

Example Input: Question: Is sIRT1 required for oncogenic transformation of neural stem cells and for the survival of `` cancer cells with neural stemness '' in a p53-dependent manner?
Answer: These results indicate that expression of SIRT1 in cancer cells with neural stemness plays an important role in suppressing p53-dependent tumor surveillance, the abrogation of which may be responsible not only for inducing oncogenic transformation but also for retaining the neural cancer stemness of the cells, suggesting that SIRT1 may be a putative therapeutic target in GSCs.
Example Output:
yes
