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: Is resistive heating more effective than metallic-foil insulation in an experimental model of accidental hypothermia : A randomized controlled trial?
Answer: Resistive heating more than doubles the rewarming rate compared with that produced by reflective metal foil and does so without producing an afterdrop. It is therefore likely to be useful in the prehospital setting.
Example Output: yes

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 the potent somatostatin analogue vapreotide decrease pancreas-specific complications after elective pancreatectomy : a prospective , multicenter , double-blinded , randomized , placebo-controlled trial?
Answer: The potent somatostatin analogue vapreotide does not appear to decrease postoperative complications after major pancreatectomy in patients without chronic pancreatitis.
Example Output:
no
