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: Are longer durations of antitumour necrosis factor treatment associated with reduced risk of cardiovascular events in patients with rheumatoid arthritis?
Answer: Anti-TNF therapy was associated with a significantly lower risk of cardiovascular events among patients with RA, older patients with RA and patients without prior exposure to methotrexate.

Output: yes


Input: Consider Input: Question: Does asfotase Alfa Treatment improve Survival for Perinatal and Infantile Hypophosphatasia?
Answer: Asfotase alfa mineralizes the HPP skeleton, including the ribs, and improves respiratory function and survival in life-threatening perinatal and infantile HPP.

Output: yes


Input: Consider Input: Question: Does thymidylate synthase mRNA expression predict resistance to floxuridine in a choriocarcinoma cell line?
Answer: We successfully established an FUDR-resistant human choriocarcinoma sub-line and found that the expression of TS mRNA in FUDR-resistant JeG-3 cells was related to the concentration and phase of FUDR exposure. These data suggest that TS mRNA levels would be of limited use as biomarkers for the prediction of chemoresistance to FUDR-based chemotherapy.


Output: no
