Circular references

Circular references is a computational problem, which cannot be resolved by a computer because it has no logical beginning and end, for example: Enable question Q1 if question Q2 is enabled, and enable question Q2 if question Q1 is enabled. In this example each of the questions Q1 and Q2 depends on each other, and there is no way to establish whether both should be asked or none at all.
