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: Do antioxidants attenuate myocyte apoptosis in the remote non-infarcted myocardium following large myocardial infarction?
Answer: Long-term treatment with the antioxidants probucol and pyrrolidine dithiocarbamate attenuates oxidative stress, myocyte apoptosis, caspase-3 like activity and the expression of p53, bax and caspase-3 within RM in rats after a large myocardial infarction.

Ex Output:
yes


Ex Input:
Question: Are mutational status of KIT and PDGFRA and expression of PDGFRA associated with prognosis after curative resection of primary gastrointestinal stromal tumors ( GISTs )?
Answer: Our data do not support the notion that expression of PDGFRA or mutations in KIT or PDGFRA are independent prognostic factors after curative resection of primary GIST.

Ex Output:
no


Ex Input:
Question: Do gold-induced reactive oxygen species ( ROS ) mediate suppression of monocytic mitochondrial or secretory function?
Answer: Our results do not indicate that ROS and redox effects play major roles in mediating the cytotoxicity of AF, GSTM or Au(III).

Ex Output:

no
