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 apoptosis inhibitor-5 overexpression associated with tumor progression and poor prognosis in patients with cervical cancer?
Answer: API5 expression is associated with pERK1/2 in a subset of cervical cancer patients and its expression predicts poor overall survival, supporting that API5 may be a promising novel target for therapeutic interventions.

Output: yes


Input: Consider Input: Question: Does prolonged hemorrhagic shock impair regeneration of plasma coagulant masses in the rabbit?
Answer: Dilutional coagulopathy corrects spontaneously within hours. Normovolemic shock prolongs dilutional coagulopathy not by impairment of factor regeneration but because of further (internal) dilution due to plasma expansion. Rapid correction of dilutional coagulopathy is likely to necessitate cryoprecipitate administration.

Output: no


Input: Consider Input: Question: Are international trends in the incidence of bone cancer related to drinking water fluoridation?
Answer: The mortality/incidence ratio, but not the incidence rate (IR), has dropped sharply since then, which erodes the basis of past inferences relating cancer mortality to fluoridation.


Output: no
