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: Do inpatient admission for febrile seizure and subsequent outcomes differ in children with vaccine-associated versus non-vaccine associated febrile seizures?
Answer: The risk of hospitalization for index FS or select subsequent FS outcomes did not differ between VA or NVA-FS. This suggests that the follow-up care of children with VA-FS does not warrant attention beyond that for NVA-FS.

Ex Output:
no


Ex Input:
Question: Does inhibition of peripheral FAAH depress activities of bladder mechanosensitive nerve fibers of the rat?
Answer: To our knowledge we report for the first time that inhibiting peripheral FAAH depresses the Aδ and C-fiber activity of primary bladder afferents via CB1 and CB2 receptors. CB antagonists alone exerted facilitatory effects on single unit afferent activity during bladder filling in rats. The endocannabinoid system may be involved in physiological control of micturition as regulators of afferent signals.

Ex Output:

yes
