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 tumor invasion depth a useful pathologic assessment for predicting outcomes in cervical squamous cell carcinoma after neoadjuvant radiotherapy?
Answer: The TID or TIDC measured at the cervical internal surface is a useful and easily applied pathologic prognostic factor for distant metastasis and survival outcomes in patients with cervical squamous cell carcinoma treated with neoadjuvant RT or CCRT.
Example Output: yes

Example Input: Question: Does a novel biomechanical device improve gait pattern in patient with chronic nonspecific low back pain?
Answer: Patients with NSLBP treated with the novel biomechanical device for 3 months increased walking speed through longer step length and eliminated asymmetrical differences.
Example Output: yes

Example Input: Question: Is severity of hearing impairment positively associated with urine albumin excretion rate in patients with type 2 diabetes?
Answer: The present study showed increased albuminuria was positively associated with the severity of hearing impairment among patients with type 2 diabetes. Screening for hearing impairment in diabetic patients who develop albuminuria might provide early detection of hearing impairment.
Example Output:
yes
