True but if we're talking USA, Piedmont is the name for a region of Virginia, North and South Carolina, and Georgia. The Piedmont Triad of NC is probably the best known "Piedmont" in the US, since there's a major airport with that name.
Give him/her a break. I'm guessing English is not the first language and some of us do well to do these quizzes with English as our first language. Such as me myself probably maybe.
Mato Grosso is a political state in Brazil, but is not considered as a region.
It should be better Pantanal, Amazônia, Sertão, Campos Sulinos...
these are regions limited by its own similar characteristics, and not merely a political division.
Well, I'm Brazilian, so I know better. Mato Grosso is a State of my country. Saying it's a region is the same as saying Florida is a region or on the other way round saying New England is a State. For the sake of accuracy, please, correct that. There are 5 major regions in Brazil: Norte, Nordeste, Centro-Oeste, Sudeste and South and dozens other microregions such as Pantanal, Sertão Nordestino, Vale do Paraíba, Chapada Diamantina, Pampas Gaúchos, Serra da Mantiqueira, Floresta Amazônica and so on.
Region means area... so if there is a piece of land with a name, it is a region. If you are talking official you get names like state, department, district, provence etc,
While correct, the Romanian area is far, far more widely known to the point where it's practically irrelevant, particularly after when "Texas" is the first item.
yeah... though I made a similar point above, it wasn't meant to mean that the quiz should be changed. There are a thousand or more place names in the Americas that were named for other places in Europe or elsewhere.
It's always odd to look at a map of America and be able to say "oh, this must be where people from my home county emigrated to" since all the names are the same.
Cork - on its own - is a city in County Cork. Most Irish counties are referred to in this way, because many of them are named after towns or cities within them. The same thing also happens in the UK: you might live in County Durham, but not necessarily in the city of Durham. So, you need to actively use the "County" part of the name so as to specify.
Not to split a hair, but Flanders is actually split between Belgium and France. The biggest city in North France, Lille, is commonly known as "The Capital Of Flanders".
Using Siberia for Russia feels quite weird... for all the others (I believe) those are administrative regions, but Siberia is just geographical and doesn't have any significance otherwise
