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: 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.

Ex Output:
yes

Ex Input:
Question: Is statin use associated with reduced risk of skin cancer : a meta-analysis?
Answer: Our meta-analysis does not support a potential role of statin use in the prevention of skin cancer.

Ex Output:
no

Ex Input:
Question: Are pre-transplant impedance measures of reflux associated with early allograft injury after lung transplantation?
Answer: Prolonged bolus clearance, increased total distal reflux episodes, and increased total proximal reflux episodes on pre-transplant MII-pH were associated with decreased time to early allograft injury after lung transplantation. Routine pre-transplant MII-pH may provide clinically relevant data regarding transplant outcomes and peri-transplant care.

Ex Output:
yes
