The correct answer is D. Most European nations are part of the European Union.
Explanation:
The map shows the European nations and whether these belong or not to the European Union (economic and political alliance). In this map, the countries in blue are those that are already part of the union, the countries in red are candidates, and the countries in green do not belong to the union. In this context, most of the European countries are part of this union. Indeed, there are around 24 countries in blue (members of the union) and only around 9 countries in green (countries that are not part of the union). Besides this, member countries include nations such as France, Spain, Germany, Greece, and Italy; while non-members include Russia, Ukraine, and Belarus. According to this, one true statement about the map is statement D.
Answer:

This bears credence to the fact that the abacus was already widely used then.
An abacus was used to count numbers.
