You will be given a definition of a task first, then some input of the task.
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.

Question: Does tERT promoter mutation predict radioiodine refractory in distant metastatic differentiated thyroid cancer?
Answer: TERT promoter mutation closely associates with non-RAI-avidity in DM-DTC, and when comparing with BRAF mutation, TERT mutation manifested a worse negative influence on RAI uptake. It could also be used as a predictive marker to early identify refractory to RAI.
Output:
yes
