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: Does proper timing of adjuvant chemotherapy affect survival in patients with stage 2 and 3 gastric cancer?
Answer: There is insufficient evidence to suggest starting adjuvant chemotherapy within 4 weeks after surgery for patients with D2 resected stage 2 and 3 gastric cancer. However, delayed treatment of adjuvant chemotherapy after 8 weeks showed worse survival outcomes than early and intermediate treatment initiation, suggesting that adjuvant chemotherapy should be considered start within 8 weeks after radical resection.
Example Output: yes

Example Input: Question: Does effective inhibition of nitric oxide production by aminoguanidine reverse hypotension in endotoxaemic rats?
Answer: AG inhibited NO formation in a dose-dependent way. Yet, AG had no haemodynamic effects, suggesting a minor cardiovascular influence of iNOS in this endotoxin model, in parallel to what has been found in microbial sepsis.
Example Output: no

Example Input: Question: Is visceral adiposity associated with altered myocardial glucose uptake measured by ( 18 ) FDG-PET in 346 subjects with normal glucose tolerance , prediabetes , and type 2 diabetes?
Answer: Our findings indicate visceral adiposity is strongly associated with the alteration of myocardial glucose uptake evaluated by (18)FDG-PET, and its association further relates to T2DM.
Example Output:
yes
