Article: In southeast Europe agrarian societies first appeared in the 7th millennium BC, attested by one of the earliest farming sites of Europe, discovered in Vashtemi, southeastern Albania and dating back to 6,500 BC. Anthropomorphic figurines have been found in the Balkans from 6000 BC, and in Central Europe by c. 5800 BC (La Hoguette). Among the earliest cultural complexes of this area are the Sesklo culture in Thessaly, which later expanded in the Balkans giving rise to Starcevo-Koros (Cris), Linearbandkeramik, and Vinca. Through a combination of cultural diffusion and migration of peoples, the Neolithic traditions spread west and northwards to reach northwestern Europe by around 4500 BC. The Vinca culture may have created the earliest system of writing, the Vinca signs, though archaeologist Shan Winn believes they most likely represented pictograms and ideograms rather than a truly developed form of writing. The Cucuteni-Trypillian culture built enormous settlements in Romania, Moldova and Ukraine from 5300 to 2300 BC. The megalithic temple complexes of Ggantija on the Mediterranean island of Gozo (in the Maltese archipelago) and of Mnajdra (Malta) are notable for their gigantic Neolithic structures, the oldest of which date back to c. 3600 BC. The Hypogeum of al-Saflieni, Paola, Malta, is a subterranean structure excavated c. 2500 BC; originally a sanctuary, it became a necropolis, the only prehistoric underground temple in the world, and showing a degree of artistry in stone sculpture unique in prehistory to the Maltese islands. After 2500 BC, the Maltese Islands were depopulated for several decades until the arrival of a new influx of Bronze Age immigrants, a culture that cremated its dead and introduced smaller megalithic structures called dolmens to Malta. In most cases there are small chambers here, with the cover made of a large slab placed on upright stones. They are claimed to belong to a population certainly different from that which built the previous megalithic temples. It is presumed the population arrived from Sicily because of the similarity of Maltese dolmens to some small constructions found in the largest island of the Mediterranean sea.

Question: Where was one of earliest farming sites in Europe found?
Ans: Vashtemi, southeastern Albania

Article: In some countries, such as Britain and Germany during the Second World War, the Soviet Union and NATO's Allied Command Europe, ground based air defence and air defence aircraft have been under integrated command and control. However, while overall air defence may be for homeland defence including military facilities, forces in the field, wherever they are, invariably deploy their own air defence capability if there is an air threat. A surface-based air defence capability can also be deployed offensively to deny the use of airspace to an opponent.

Question: Which country's air defence and aircraft has been under integrated command and control?
Ans: Soviet Union

Article: The 2010 maternal mortality rate per 100,000 births for Guinea Bissau was 1000. This compares with 804.3 in 2008 and 966 in 1990. The under 5 mortality rate, per 1,000 births, was 195 and the neonatal mortality as a percentage of under 5's mortality was 24. The number of midwives per 1,000 live births was 3; one out of eighteen pregnant women die as a result of pregnancy. According to a 2013 UNICEF report, 50% of women in Guinea Bissau had undergone female genital mutilation. In 2010, Guinea Bissau had the 7th highest maternal mortality rate in the world.

Question: What was the 1990 maternal mortality rate per 100,000 births?
Ans: 966

Article: The first non-stop transatlantic crossing was made by the British airship R34 in 1919. Regular passenger service resumed in the 1920s and the discovery of helium reserves in the United States promised increased safety, but the U.S. government refused to sell the gas for this purpose. Therefore, H2 was used in the Hindenburg airship, which was destroyed in a midair fire over New Jersey on 6 May 1937. The incident was broadcast live on radio and filmed. Ignition of leaking hydrogen is widely assumed to be the cause, but later investigations pointed to the ignition of the aluminized fabric coating by static electricity. But the damage to hydrogen's reputation as a lifting gas was already done.

Question: What year did the airship get destroyed?
Ans:
1937
