Repeat question

Although the editors of the "Kto khochet stat' millionerom?" game show are trying to compose a set of questions for each contestants that can not be repeated by other participants, in the Russian version's history have been moments when the same question could be repeated in another episode after a certain amount of time (for example, after few years). In some cases, the repetition of the question could not be complete: the answers or their sequence could change.
