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: Is nuchal cord associated with adverse perinatal outcome?
Answer: Nuchal cord is not associated with adverse perinatal outcome. Thus, labor induction in such cases is probably unnecessary.
Example Output: no

Example Input: Question: Does a migrating ciliary gate compartmentalize the site of axoneme assembly in Drosophila spermatids?
Answer: Our findings demonstrate that the ciliary gate can migrate away from the base of the cilium, thereby functioning independently of the centriole and of a static interaction with the axoneme to compartmentalize the site of axoneme assembly.
Example Output:
yes
