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: Does expression microarray identify the unliganded glucocorticoid receptor as a regulator of gene expression in mammary epithelial cells?
Answer: This work presents the first identification of targets of unliganded GR. We propose that the balance between targets of liganded and unliganded GR signaling is responsible for controlling differentiation and apoptosis, respectively, and suggest that gene regulation by unliganded GR may represent a mechanism for reducing the risk of breast tumourigenesis by the elimination of abnormal cells.
Example Output: yes

Example Input: Question: Does vorapaxar , an oral PAR-1 receptor antagonist , affect the pharmacokinetics of rosiglitazone?
Answer: Coadministration of vorapaxar with rosiglitazone or drugs metabolized via CYP2C8 is unlikely to cause a significant pharmacokinetic interaction.
Example Output:
no
