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.

Ex Input:
Question: Are synthetic antifibrinolytics associated with an increased incidence of baffle fenestration closure after the modified Fontan procedure?
Answer: Use of epsilon-aminocaproic acid and tranexamic acid is not associated with early baffle fenestration closure after the modified Fontan procedure. It is concluded that these agents can be used without increasing the risk of spontaneous baffle fenestration closure.

Ex Output:
no

Ex Input:
Question: Is hyperglycemia associated with increased risk of patient delay in pulmonary tuberculosis in rural areas?
Answer: Patient delay appears to be a serious problem in this rural area with a high prevalence of tuberculosis. Hyperglycemia is independently associated with an increased probability of patient delay, which, in turn, may result in more serious clinical manifestations.

Ex Output:
yes

Ex Input:
Question: Is the impairment of reproduction in db/db mice mediated by intraovarian defective leptin signaling?
Answer: We confirmed that impairment of reproduction in intact db/db mice is not mediated by intraovary intact/defective leptin signaling even in face of a divergent modulation by gonadotropins.

Ex Output:
no
