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: Does pI3K and Bcl-2 inhibition prime glioblastoma cells to apoptosis through downregulation of Mcl-1 and Phospho-BAD?
Answer: Combination therapy with ABT-263 and GDC-0941 has novel therapeutic potential by specifically targeting aberrantly active, deregulated pathways in GBM, overcoming endogenous resistance to apoptosis.
Example Output: yes

Example Input: Question: 's it just the big kids : both high and low BMI impact bracing success for adolescent idiopathic scoliosis?
Answer: Based on our results, children on either end of the BMI spectrum are more likely to fail brace treatment for scoliosis than their mid-BMI counterparts. In high-BMI patients, this appears to be in large part attributable to an inadequacy of in-brace curve correction as well as to poorer brace compliance, while a low BMI appears to be an independent risk factor for brace failure.
Example Output: no

Example Input: Question: Do small doses of droperidol present relevant torsadogenic actions : a double-blind , ondansetron-controlled study?
Answer: In men without cardiovascular disorders small doses (1.25 mg) of droperidol prophylaxis induced transient QTc prolongation without changes in transmural dispersion of repolarization. The apparently low risk of the drug applies only in low risk male patients with a low pro-QTc score.
Example Output:
no
