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: Do nAT1 genotypes predict response to mesalamine in patients with ulcerative colitis?
Answer: NAT1 genotypes do not predict response or side effects to mesalamine in patients with UC. Variations caused by non-genomic effects may be associated with the clinical response to 5-ASA.
Example Output: no

Example Input: Question: Is early systemic sclerosis : serum profiling of factors involved in endothelial , T-cell , and fibroblast interplay marked by elevated interleukin-33 levels?
Answer: Our study suggests that an endothelial, T-cell and fibroblast activation can be present in patients with early SSc and it is associated with a distinct profile of circulating factors involved in the cross-talk of these cells. The marked increase of IL-33 in early SSc patients suggests new routes of investigation of cell-cell dynamics in target tissues predating overt disease manifestations, thus opening to new therapeutic approaches.
Example Output: yes

Example Input: Question: Does rAMP1 suppress mucosal injury from dextran sodium sulfate-induced colitis in mice?
Answer: The findings of this study suggest that RAMP1 exerted mucosal protection in DSS-induced colitis via attenuation of recruitment of inflammatory cells and of pro-inflammatory cytokines. This article is protected by copyright. All rights reserved.
