Instructions: 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: Question: Does methotrexate inhibit NF-B activity via long intergenic ( noncoding ) RNA-p21 induction?
Answer: Our findings support a model whereby depressed levels of lincRNA-p21 in RA contribute to increased NF-B activity. MTX decreases basal levels of NF-B activity by increasing lincRNA-p21 levels through a DNA PKcs-dependent mechanism.
Output:
yes
