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 monosialotetrahexosylganglioside inhibit the Expression of p-CREB and NR2B in the Auditory Cortex in Rats with Salicylate-Induced Tinnitus?
Answer: These data suggest that chronic salicylate administration induces tinnitus via upregulation of p-CREB and NR2B expression, and that GM1 can potentially be used to treat tinnitus.
Example Output: yes

Example Input: Question: Does prolonged Achilles Tendon Vibration Alter the Neuromuscular Performance of Plantar Flexor Muscles?
Answer: The current study demonstrates that 30 min of Achilles tendon vibration at a low or high frequency using a portable stimulator did not affect the neuromuscular performance of the plantar flexor muscles. These results emphasize the limits of tendon vibration, whatever the frequency applied, for inducing neuromuscular fatigue.
Example Output:
no
