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: Does milrinone attenuate serotonin-induced pulmonary hypertension and bronchoconstriction in dogs?
Answer: We studied the effects of milrinone on serotonin-induced pulmonary hypertension and bronchoconstriction in dogs. Milrinone produces pulmonary vasodilation and bronchodilation, whose effects may not be caused by beta-adrenoceptor activation. In addition, this drug may be more sensitive to phosphodiesterase III in the airway smooth muscle than that in pulmonary vascular smooth muscle.
Example Output: yes

Example Input: Question: Does brivaracetam differentially affect voltage-gated sodium currents without impairing sustained repetitive firing in neurons?
Answer: The lack of effect of BRV on SRF in neurons suggests that the reported inhibition of BRV on VGSC currents does not contribute to its antiepileptic properties.
Example Output: yes

Example Input: Question: Do pilot study of glaucoma drainage implant surgery supplemented with reticulated hyaluronic acid gel in severe glaucoma?
Answer: In eyes with severe glaucoma, the intraoperative application of crosslinked sodium HA gel may improve the efficacy of GDI surgery.
Example Output:
yes
