Consider the following countries:

1. Finland

2. Germany

3. Norway

4. Russia

How many of the above countries have a border with the North Sea?

The correct option is Only two.

To determine how many of the given countries border the North Sea, let us examine the geography of each country listed:
1. Finland: Finland is located in Northern Europe and is bordered by the Baltic Sea, specifically the Gulf of Bothnia to the west and the Gulf of Finland to the south. It does not have a coastline along the North Sea.
2. Germany: Germany has coastlines along two seas in the north: the Baltic Sea to the northeast and the North Sea to the northwest. Therefore, Germany borders the North Sea.
3. Norway: Norway occupies the western and northern parts of the Scandinavian Peninsula. Its extensive coastline borders the North Sea in the southwest, the Norwegian Sea in the west, and the Barents Sea in the north. Therefore, Norway borders the North Sea.
4. Russia: While Russia is the largest country in the world and borders many oceans and seas (such as the Baltic Sea, Black Sea, Caspian Sea, and the Arctic and Pacific Oceans), it does not extend to or border the North Sea.

Out of the four listed countries, only Germany and Norway border the North Sea. Thus, exactly two of the countries meet the criterion.
