Involvement - France is one of the six founding member of theEU.
It is one of the 6 core founding countries of the EU, so France technically founded & joined the EU in 1958.
Euro was introduced in 1999, and since 2012 France uses the Euro exclusively.
Because France used to be a powerful colonialist, they have overseas regions, territories which are not located in Europe, but their citizens are european citizens. For example, French Guiana people can live & work in Europe based on their French citizenship.
Because of its resemblance to a hexagon, france is sometimes called l’Hexagone
France abolished the guillotine as the capital method of punishment only in 1981 - 23 years after they founded the EU. The last person to be punished in France by guillotine was executed on 10 September 1977.
If i'm not wrong, it's true
What you're looking for in here is the hardness: a material can scratch another material if it's harder than it.
So the desired material cannot be harder than amphibole, which has a hardness of 6.
But it has to be harder than fluorite, which has a hardness of 4.
So we're looking for a hardness of between 4 and 6 and from the table we see it's magnesite (we'll need a hard magesite) - this is the correct answer!
