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: Is hyperglycemia associated with increased risk of patient delay in pulmonary tuberculosis in rural areas?
Answer: Patient delay appears to be a serious problem in this rural area with a high prevalence of tuberculosis. Hyperglycemia is independently associated with an increased probability of patient delay, which, in turn, may result in more serious clinical manifestations.
Example Output: yes

Example Input: Question: Is statin use associated with reduced risk of skin cancer : a meta-analysis?
Answer: Our meta-analysis does not support a potential role of statin use in the prevention of skin cancer.
Example Output: no

Example Input: Question: Are the effects of high glucose on human endothelial cell growth and gene expression mediated by transforming growth factor-beta?
Answer: These combined observations indicate that (a) endothelial cells exposed to high glucose do not secrete TGF-beta in excess of control cells, (b) there are growth-inhibitory effects of high glucose that are independent of TGF-beta, and (c) high glucose and TGF-beta exert their effects through distinct pathways and at different loci.
Example Output:
no
