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 ultrasound-guided synovial biopsy of the wrist alter subsequent clinical or ultrasound disease activity assessments : a prospective study for incorporation of imaging in clinical trials?
Answer: In this population, UGSB of the wrist did not significantly alter subsequent clinical or US assessments, indicating that a wrist joint, which has undergone UGSB, may be incorporated into an US dataset or clinical outcome assessment tools, such as the DAS-28, without prejudice.
Output:
no
