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: Has survival after recurrent esophageal carcinoma improved over the past 18 years?
Answer: Survival after recurrent EC in patients who undergo FU without routine imaging after esophagectomy is approximately 3months and has not improved over the past 18years.
Example Output: no

Example 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.
Example Output: no

Example Input: Question: Does fibroblast Growth Factor Receptor 3 Deficiency Impair the Osteoanabolic Action of Parathyroid Hormone on Mice?
Answer: Bone anabolic effects of PTH were not impaired by the absence of FGFR3, suggesting that the FGFR3 signaling may not be required for osteoanabolic effects of PTH activities.
Example Output:
no
