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.

Input: Consider Input: Question: Does dietary beet pulp decrease taurine status in dogs fed low protein diet?
Answer: These results do not support the hypothesis that RB is likely to be a primary cause of lamb meal and rice diets, increasing the risk of taurine deficiency in large dogs. However these indicate that BP may contribute to a decrease taurine status in dogs by increasing excretion of fecal BA and decreasing protein digestibility, thus decreasing the bioavailability of sulfur amino acids, the precursors of taurine.

Output: yes


Input: Consider 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.

Output: yes


Input: Consider Input: Question: Does retinal function in rabbits improve 4-5 months after terminating treatment with vigabatrin?
Answer: Four to five months after terminating treatment with vigabatrin the rabbit full-field ERG remains reduced in isolated cone b-wave amplitude indicating that vigabatrin induced retinal dysfunction may be irreversible. However, immunohistology is normal after a period without treatment, implying that the previously described changes in retinal morphology and glial cell activity are reversible, and probably exist only during treatment.


Output: no
