Passage: A part of the Province of East Prussia until after World War I, in 1920 Nemirseta was with the Klaipėda Region (Memelland) separated from Germany according to the Treaty of Versailles. It was put under administration of the League of Nations and controlled by French forces, until the 1923 Klaipėda Revolt, after which it was annexed by Lithuania. For a brief period Nemirseta again became a border checkpoint, when Lithuanian Foreign Minister Juozas Urbšys under pressure of Nazi Germany in March 1939 signed an agreement after which the Klaipėda Region was reannexed to the German nation. The secret protocol of the Molotov–Ribbentrop Pact allocated it to the German sphere of influence.
 Link Information:  It was signed on 28 June 1919 in Versailles Question: On what date was the treaty signed that separated Nemirseta from Germany?

Passage: Azurite is unstable in air, however it was used as a blue pigment in antiquity. Azurite is naturally occurring in Sinai and the Eastern Desert of Egypt. It was reported by F. C. J. Spurrell (1895) in the following examples; a shell used as a pallet in a Fourth Dynasty (2613 to 2494 BCE) context in Meidum, a cloth over the face of a Fifth Dynasty (2494 to 2345 BCE) mummy also at Meidum and a number of Eighteenth Dynasty (1543–1292 BCE) wall paintings. Depending on the degree of fineness to which it was ground, and its basic content of copper carbonate, it gave a wide range of blues. It has been known as mountain blue or Armenian stone, in addition it was formerly known as Azurro Della Magna (from Italian). When mixed with oil it turns slightly green. When mixed with egg yolk it turns green-grey. It is also known by the names blue bice and blue verditer, though verditer usually refers to a pigment made by chemical process. Older examples of azurite pigment may show a more greenish tint due to weathering into malachite. Much azurite was mislabeled lapis lazuli, a term applied to many blue pigments. As chemical analysis of paintings from the Middle Ages improves, azurite is being recognized as a major source of the blues used by medieval painters. Lapis lazuli (the pigment ultramarine) was chiefly supplied from Afghanistan during the Middle Ages, whereas azurite was a common mineral in Europe at the time. Sizable deposits were found near Lyons, France. It was mined since the 12th century in Saxony, in the silver mines located there.
 Link Information: Saxony ( ; ; ; ), officially the Free State of Saxony (German: , Upper Sorbian: ), is a landlocked federal state of Germany Question: What country was azurite mined in during the 12th century?

Ex Output:
Answer: Germany


Ex Input:
Passage: Born in Machakos, he began running seriously around 2004 in the hope he could make a living out of the sport. Ndiku made his international debut at the 2007 World Youth Championships in Athletics, coming fourth in the 2000 metres steeplechase event. His technique was poor and his coach, Paul Mutwii, turned to Boniface Teren, the Kenyan national steeplechase coach, for help. Working with Teren, Ndiku's technique over the barriers greatly improved and one year later he won the gold medal at the 2008 World Junior Championships in Athletics, beating Uganda's Benjamin Kiplagat who had built up a sizeable lead in the early stages. Ndiku's winning time of 8:17.28 minutes was enough to rank the 16-year-old in the top 25 athletes in the world that year, as well as being the fastest ever recorded by a youth category athlete. His flat speed also improved, as he won the 1500 metres at the Commonwealth Youth Games that year. He also competed in Japan that year. After signing up with the Hitachi Cable corporate running team, he set track bests of 7:54.04 minutes for the 3000 metres, 13:21.17 minutes for the 5000 metres and 28:08.28 minutes for the 10,000 metres.
 Link Information: none Question: What is the lowest point of the place where Ndiku was born?

Ex Output:

Answer: none
