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 Q]: Question: Is the WFS1 ( Wolfram syndrome 1 ) a major susceptibility gene for the development of psychiatric disorders?
Answer: Our results suggest that WFS1 is not a major susceptibility gene for the development of psychiatric disorders in our population.
[EX A]: no

[EX Q]: Question: Do lipopolysaccharide and cytokines inhibit rat cardiomyocyte contractility in vitro?
Answer: Prolonged exposure of ARVM to a mixture of LPS and inflammatory cytokines inhibits cell contractility. The effect is mediated by the inhibition of Ca(2+) influx via LTCC, and partially opposed by the inhibition of Na(+)/Ca(2+) exchange. Because both mechanisms are commonly seen in animal models of SIC, we conclude that prolonged challenge with Cytomix-100 of ARVM may represent an accurate in vitro model for SIC.
[EX A]: yes

[EX Q]: Question: Is epithelial ovarian tumors in the reproductive age group : age an independent prognostic factor?
Answer: Epithelial ovarian cancer patients age 30 years or younger have a more favorable prognosis because of a higher rate of early stage, low grade tumors. Patients aged 31-40 years also show a more favorable disease profile and clinical outcome, although to a lesser extent, than the average ovarian cancer population. Age does not emerge as an independent prognostic factor for ovarian carcinoma in women younger than 40 years.
[EX A]:
no
