Thank you for taking the effort to submit your test for the contest. Unfortunately, this test will not be able to receive a prize: 1) Too many missing explanations. More than 10 explanations simply repeat the correct answer. E.g #q1, #q2, #q4, etc. 2) Major language issues. Too many mistakes in questions, answers and explanations (grammar, punctuation, typos, style). E. g. "in the Africa" (in Africa), "USA" (the USA), "In which city lives the biggest amount of people in the world?" (In which city does the biggest number of people in the world live?), etc.
3.The largest country in the Eastern Europe is Russia. Even half of Russia (as written in your explanation) is much bigger than Ukraine. Russia reaching to the Ural Mountains is considered as Europe. https://en.wikipedia.org/wiki/Eastern_Europe

However, even if the measurement based on three properties (city proper, metropolitan area, urban area), there other cities which are larger in the area than both Beijing and New York.
