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 adjuvant Stereotactic Radiosurgery reduce Need for Retreatments in Patients with Meningioma Residuals?
Answer: aSRS of meningioma residuals had a positive effect on tumor control and should be considered in patients with meningioma residuals.
Example Output: yes

Example Input: Question: Is human in vitro oocyte maturation associated with increased imprinting error rates at LIT1 , SNRPN , PEG3 and GTL2?
Answer: There is no significant increase in imprinting mutations at LIT1, SNRPN, PEG3 and GTL2 after IVM of cumulus-enclosed GV oocytes from small antral follicles in minimally stimulated cycles without hCG priming.
Example Output: no

Example Input: Question: Does transfusion of recently donated ( fresh ) red blood cells ( RBCs ) improve survival in comparison with current practice , while safety of the oldest stored units is yet to be established : a meta-analysis?
Answer: RCTs established that transfusion of 1- to 10-day-old stored RBCs is not superior to current practice. The apparent discrepancy in mortality between analyses of RCTs and observational studies may in part relate to differences in hypotheses tested and ages of stored RBCs studied. Further trials investigating 1- to 10-day-old stored RBC benefits would seem of lower priority than studies to determine whether 4- to 6-week stored units have safety and efficacy equivalent to the 2- to 3-week-old stored RBCs commonly transfused today.
Example Output:
no
