Actually, the questions listed by integrity02 do not include any probable-lie "control" questions. The first two are irrelevant questions, and the last three are relevant.

A standard ploy used by NSA polygraphers is to falsely tell applicants that the question about their name is a very important one, because people have attempted to infiltrate the NSA using fake names in the past. Thus, it is conceivable that in practice, NSA is using this irrelevant question as a kind of "hidden control" question. But I have found no documentation that such is the case.
