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.

Ex Input:
Question: Does indoleamine 2,3-dioxygenase inhibition alter the non-coding RNA transcriptome following renal ischemia-reperfusion injury?
Answer: These results suggest a biologic role for non-coding, IDO-dependent genes in regulating the early response to IRI.

Ex Output:
yes


Ex 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.

Ex Output:
yes


Ex Input:
Question: Are hot flashes predictive for serum concentrations of tamoxifen and its metabolites?
Answer: No univariate associations were observed between concentrations of active tamoxifen metabolites and either the frequency or severity of hot flashes during treatment. However, the frequency of hot flashes may be exacerbated by higher serum concentrations of tamoxifen and its metabolites in post-menopausal women with a history of hot flashes prior to tamoxifen treatment.

Ex Output:

no
