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.

Input: Consider Input: Question: Does peroxiredoxin II negatively regulate lipopolysaccharide-induced osteoclast formation and bone loss via JNK and STAT3?
Answer: We suggest that PrxII could be useful in the development of a novel target for inflammatory bone loss.

Output: yes


Input: Consider Input: Question: Are arterial stiffness and central arterial wave reflection associated with serum uric acid , total bilirubin , and neutrophil-to-lymphocyte ratio in patients with coronary artery disease?
Answer: N/L ratio and serum UA and TB levels might be used to risk-stratify patients with respect to arterial stiffness in CAD patients, especially in the presence of ACS.

Output: yes


Input: Consider Input: Question: Is flat-footedness a disadvantage for athletic performance in children aged 11 to 15 years?
Answer: No disadvantages in sport performance originating from flat-footedness were confirmed. Children with flat and children with "normal" feet were equally successful at accomplishing all motor tests; thus, we suggest that there is no need for treatment of flexible flat feet with the sole purpose of improving athletic performance, as traditionally advised by many.


Output: no
