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: Are respiratory disorders more common in farmers . Results from a study on Icelandic animal farmers?
Answer: The prevalence of respiratory disorders and symptoms among Icelandic farmers is currently similar to non-farmers. This may suggest that modernization of the agricultural environment has had a positive effect on workers' health.
Example Output: no

Example Input: Question: Is neutrophil-lymphocyte ratio a reliable predictive marker for early-stage diabetic nephropathy?
Answer: Increased NLR was significantly associated with DN, and high NLR values may be a reliable predictive marker of early-stage DN.
Example Output: yes

Example 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.
Example Output:
yes
