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 induction pegylated interferon alfa-2a and high dose ribavirin increase SVR in heavy patients with HCV genotype 1 and high viral loads?
Answer: In patients infected with HCV genotype 1 who are difficult to treat (high viral load, body weight 85 kg), a 12-week induction regimen of peginterferon alfa-2a and/or higher-dose ribavirin is not more effective than the standard regimen.

Ex Output:
no

Ex Input:
Question: Does chlamydia pneumoniae hide inside apoptotic neutrophils to silently infect and propagate in macrophages?
Answer: Taken together, our data suggest that C. pneumoniae uses neutrophil granulocytes to be silently taken up by long-lived macrophages, which allows for efficient propagation and immune protection within the human host.

Ex Output:
yes

Ex Input:
Question: Is the transposable element environment of human genes associated with histone and expression changes in cancer?
Answer: Taken together, these results suggest that the presence of TEs near genes could favor important variation in gene expression when the cell environment is modified.

Ex Output:
yes
