My most upvoted answer in Quora is me talking about China.
«Officially:
There is only one China. China includes mainland China and Taiwan. There are two political entities that claim to be the rightful government of all China (both mainland and Taiwan): they are the People’s Republic of China (PRC), and the Republic of China (ROC).»

The answer was posted in 2017, and it had a peek of views in early 2020. I wonder why.
The second most upvoted answer is related to New World monkeys and vegetation rafts.
It might be the most upvoted, if we add that it was shared in another space, and combined they got more upvotes than the China one, in a lesser time.
«The split between Old World monkeys and New World monkeys happened nearly 40 million years ago. By this time South America and Africa were already separated by the Atlantic Ocean. The gap was shorter than today, but it was already an ocean. Other non-simian primates only live in the Old World (Eurasia and Africa). It is reasonable to think, and so far the fossil record confirms it, that primates originated in the old world and at some point they migrated to the Americas.»

It refers to the Caucasus, a mountainous region between the Black Sea and the Caspian Sea, currently under the recognized countries of Russia, Georgia, Armenia, Azerbaijan, Iran and Turkey; as well as several de facto countries.
The word was used by German physiologist Johann Friedrich Blumenbach, one of the first people who attempted a scientific study of human races. »

My fourth most upvoted answer was a nice trivia.
«Paris (France), Brasilia (Brazil): 8,735 km (5,427 mi)
Second place (and just in case you refuse to consider French Guiana as main French territory):
Moscow (Russia), Pyongyang (DPRK): 6,420 km (3,989 mi)
[Edit: Actually third after Paris-Paramaribo, still largest distance for continuous land territories. Thank to Colin Myrick for noticing.]»
