Time for yet another completely random, unimportant question:
In the US/Canada (I assume) there is a popular TV gameshow that quizzes contestants called "Jeopardy." The style is like so:
-The host (Alex Trebec) provides the contestants with an "answer" to a question. For example "This city is home of the Kremlin and capital of Russia."
-The contestants must then give the correct "question" -- "What is Moscow?"
So my question is this; assuming you wanted to translate the question part of the game, how would you do so? "Что это такая Москва?" "Что такая Москва?" "Какая Москва?"
