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.

Input: Consider Input: Question: Is diffuse musculoskeletal pain associated with low vitamin D levels or improved by treatment with vitamin D?
Answer: Low vitamin D levels are not associated with diffuse musculoskeletal pain, and treatment with vitamin D does not reduce pain in patients with diffuse pain who have low vitamin D levels.

Output: no


Input: Consider Input: Question: Do elevated serum progesterone levels on the day of human chorionic gonadotropin administration predict outcome in assisted reproduction cycles?
Answer: Serum P levels before hCG administration do not predict the outcome of ART cycles in patients suppressed with GnRH-a before hMG stimulation. Lower fertilization rates observed in the high P cycles did not have an effect on clinical outcome.

Output: no


Input: Consider Input: Question: Does 1,8-Cineole ameliorate oxygen-glucose deprivation/reoxygenation-induced ischaemic injury by reducing oxidative stress in rat cortical neuron/glia?
Answer: Collectively, these results suggest 1,8-cineole as a potentially effective neuroprotective and anti-oxidative candidate for the treatment of patients with ischaemic stroke.


Output: yes
