The quiz is supposed to be about countries, but some of the answers are not about countries. For example, the great pyramid is, of course, in Egypt, but when I answered Egypt - knowing you were asking about countries - it did not accept that. The same thing with the Great Wall of China. And the Trans-Siberian Railroad, which on a "countries" quiz would be Russia. Also, I am not sure the Tallest Manmade Structure is the Burj Khalifa. For years, it was a radio tower in North Dakota in the U.S. That may have changed, and if you mean "Building" you may have the correct answer, but "structure" I would assume counts everything.
I know doing these quizzes is hard sometimes (believe me I've tried) and I do appreciate the effort.
The quiz does not ask for countries unless it is specifically in the question so the answers for the pyramid and the railroad are in line with the question.
As for the highest manmade structure, the Burj Khalifa appears to be recognised as the tallest structure since 2010. Single towers are a slightly different definition to a building but either way the Burj is taller than any recorded towers or masts.
