Greek banks open a new branch somewhere in the Balkans on an almost weekly basis. The Greek telecommunications company OTE has become a strong investor in Yugoslavia and other Balkan countries.
Greece is the largest foreign investor of what area?

Problem: Average annual precipitation is 15 inches (380 mm), but great variations are seen. The mountain ranges block the moist Pacific air, holding moisture in the western valleys, and creating rain shadows to the east. Heron, in the west, receives the most precipitation, 34.70 inches (881 mm). On the eastern (leeward) side of a mountain range, the valleys are much drier; Lonepine averages 11.45 inches (291 mm), and Deer Lodge 11.00 inches (279 mm) of precipitation. The mountains themselves can receive over 100 inches (2,500 mm), for example the Grinnell Glacier in Glacier National Park gets 105 inches (2,700 mm). An area southwest of Belfry averaged only 6.59 inches (167 mm) over a sixteen-year period. Most of the larger cities get 30 to 50 inches or 0.76 to 1.27 metres of snow each year. Mountain ranges themselves can accumulate 300 inches or 7.62 metres of snow during a winter. Heavy snowstorms may occur any time from September through May, though most snow falls from November to March.
How much precipitation does the Grinnell Glacier recieve?

Answer: 105 inches

Problem: The UK political system, while technically a multi-party system, has functioned generally as a two-party (sometimes called a "two-and-a-half party") system; since the 1920s the two largest political parties have been the Conservative Party and the Labour Party. Before the Labour Party rose in British politics the Liberal Party was the other major political party along with the Conservatives. Though coalition and minority governments have been an occasional feature of parliamentary politics, the first-past-the-post electoral system used for general elections tends to maintain the dominance of these two parties, though each has in the past century relied upon a third party to deliver a working majority in Parliament. (A plurality voting system usually leads to a two-party system, a relationship described by Maurice Duverger and known as Duverger's Law.) There are also numerous other parties that hold or have held a number of seats in Parliament.
When was Duverger's Law passed in the UK?
