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 a common variant in the precursor miR-146a sequence predispose to cholangiocarcinoma in a large European cohort?
Answer: Our data do not support a prominent contribution of the pre-miR-146a sequence variant in the genetic predisposition to CCA. However, current studies functionally characterizing rs2910164 have proposed that distinct repertoires of target genes are addressed by genotype-specific mature miR-146a species. Given the detected trend towards a potentially protective role of GC heterozygosity, a subtle modulation of genetic CCA risk by the pre-miR-146a GC genotype may exist and should be evaluated further.
Example Output: no

Example Input: Question: Does diffusion-tensor imaging implicate prefrontal axonal injury in executive function impairment following very mild traumatic brain injury?
Answer: Impaired executive function following mTBI is associated with axonal injury involving the DLPFC.
Example Output: yes

Example Input: Question: Does n-2-mercaptopropionylglycine , a scavanger of reactive oxygen species , modify the early antiarrhythmic effect of ischaemic preconditioning in anaesthetised dogs?
Answer: We conclude that in our canine model of ischaemia/reperfusion the generation of ROS does not play a trigger role in the early PC-induced antiarrhythmic protection.
Example Output:
no
