I had to Take a Polygraph test for a job but...?

I had to take a Polygraph test for a job interview as a 911 Operator. The results showed that I failed on a question that I was 100% honest-to-god about. "Have you knowingly ever participated in a felony that you were or were not caught?" I really have not, and have no reason to lie about it; but the test says otherwise. Do you think that they would disqualify me from the test; or do you think I could do something to retake the test?
