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: Is preoperative prolonged steroid use associated with intraoperative blood transfusion in noncardiac surgical patients?
Answer: The effect of prolonged steroid use on bleeding, if any, thus seems likely to be small and is probably of limited clinical consequence. In contrast, corticosteroid use augments the risk of both systemic and wound infections.
Example Output: no

Example Input: Question: Does treatment of subclinical hypothyroidism affect bone mass as determined by dual-energy X-ray absorptiometry , peripheral quantitative computed tomography and quantitative bone ultrasound in Spanish women?
Answer: Our results indicate that adequate metabolic control through replacement treatment with L-T4 in pre- and postmenopausal women does not affect bone mass.
Example Output: no

Example Input: Question: Is drosophila glob1 required for the maintenance of cytoskeletal integrity during oogenesis?
