If we can continue to call Cote d'Ivoire the Ivory Coast (as this site does), then we can continue to call Lagos the capital of Nigeria; call it Swaziland instead of eSwatini, and continue to use Macedonia instead of North Macedonia..
Except Lagos and Abuja are two entirely different cities whereas your other examples are referring to the same place but by different appellations. That's akin to saying Philadelphia and Washington DC are the same city because Timor Leste and East Timor are often used interchangeably.
Guess you're not all that familiar with the geography of Delaware! Delaware is among the flattest states in the US - even flatter than famously-flat Kansas!
I feel like I've been living under a rock with the White Cliffs of Dover question, because I've never heard of 'em before. I thought it meant Dover as in the capital of Delaware, so I thought the question was ridiculous and there was no way France could see them across the entire Atlantic. This all happened until I looked them up...
Did a quick survey among my many French friends and colleagues: The all pronounce Cannes as "Cann". I can well believe that US Americans pronounce it differently - but if you are asking how Americans pronounce this, you should specify this in the question
The Rio Grande question might need rephrasing. The way it currently is makes it sound like a trick question, since it doesn't form part of the border between Mexico and Texas, it forms the ENTIRE border between the two.
The Rio Grande definitely forms "part of" the border between Mexico and the United States not its "entire" border! What is meant is that the entire river forms (part of) the border, but not the entire border between the two countries.
The distance between the White Cliffs of Dover and France is only about 20 miles or so. Some claim that during WW1 and WW2 people in Dover could hear the fighting going on across the Channel in France
Une enclave est soit un terrain entouré par un autre terrain qui n'a aucune issue sur la voie publique, soit un territoire ou un pays à l'intérieur d'un autre, soit un fragment de roche dans une autre roche différente, donc aucunes de ces définitions ne correspondent à la Suisse
Three wrong. Common factor? All three are US-related questions: its highest point, its trade deficit and yes, its snowy climate in Hawaii. I have long admitted my US geography isn't the best...
In the US it pretty much the same except they more less were all Christian.
Only if you have a map where Greenland is printed green.
