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: Do the biceps tendon as a measure of rotational deformity in residual brachial plexus birth palsy?
Answer: The biceps angle is a measure of rotational deformity in patients with residual brachial plexus birth palsy, and correlates better with external rotation than either the glenoid version or the PHHA. The biceps angle may be a useful measure of rotational glenohumeral deformity before and after surgery.
Example Output: yes

Example Input: Question: Does novel individual metabolic profile characterize the protein kinase B-alpha ( pkbα-/- ) in vivo model?
Answer: Specific metabolic characterization should be assessed individually. Therefore, our in silico model enables novel insights inaugurating specific primary preventive strategies targeting individual metabolic profiling precisely.
Example Output: yes

Example Input: Question: Is the combination of octreotide and midodrine superior to albumin in preventing recurrence of ascites after large-volume paracentesis?
Answer: The combination of midodrine and octreotide after LVP is not superior to albumin in delaying recurrence of ascites or preventing PCD in patients with cirrhosis. Outcomes appear to be worse in patients given octreotide and midodrine. ClinicalTrials.gov number, NCT00108355.
Example Output:
no
