Article: So an additional problem beyond canceling the unwanted reactance is of matching the remaining resistive impedance to the characteristic impedance of the transmission line. In principle this can always be done with a transformer, however the turns ratio of a transformer is not adjustable. A general matching network with at least two adjustments can be made to correct both components of impedance. Matching networks using discrete inductors and capacitors will have losses associated with those components, and will have power restrictions when used for transmitting. Avoiding these difficulties, commercial antennas are generally designed with fixed matching elements or feeding strategies to get an approximate match to standard coax, such as 50 or 75 Ohms. Antennas based on the dipole (rather than vertical antennas) should include a balun in between the transmission line and antenna element, which may be integrated into any such matching network.

Question: What is included between the transmission line and the antenna element?
Ans: balun


Article: Josip Broz Tito received a total of 119 awards and decorations from 60 countries around the world (59 countries and Yugoslavia). 21 decorations were from Yugoslavia itself, 18 having been awarded once, and the Order of the National Hero on three occasions. Of the 98 international awards and decorations, 92 were received once, and three on two occasions (Order of the White Lion, Polonia Restituta, and Karl Marx). The most notable awards included the French Legion of Honour and National Order of Merit, the British Order of the Bath, the Soviet Order of Lenin, the Japanese Order of the Chrysanthemum, the German Federal Cross of Merit, and the Order of Merit of Italy.

Question: Which government awards the Order of the Chrysanthemum?
Ans: Japanese


Article: The independence of the Thirteen Colonies in North America in 1783 after the American War of Independence caused Britain to lose some of its oldest and most populous colonies. British attention soon turned towards Asia, Africa, and the Pacific. After the defeat of France in the Revolutionary and Napoleonic Wars (1792–1815), Britain emerged as the principal naval and imperial power of the 19th century (with London the largest city in the world from about 1830). Unchallenged at sea, British dominance was later described as Pax Britannica ("British Peace"), a period of relative peace in Europe and the world (1815–1914) during which the British Empire became the global hegemon and adopted the role of global policeman. In the early 19th century, the Industrial Revolution began to transform Britain; by the time of the Great Exhibition in 1851 the country was described as the "workshop of the world". The British Empire expanded to include India, large parts of Africa and many other territories throughout the world. Alongside the formal control it exerted over its own colonies, British dominance of much of world trade meant that it effectively controlled the economies of many regions, such as Asia and Latin America. Domestically, political attitudes favoured free trade and laissez-faire policies and a gradual widening of the voting franchise. During this century, the population increased at a dramatic rate, accompanied by rapid urbanisation, causing significant social and economic stresses. To seek new markets and sources of raw materials, the Conservative Party under Disraeli launched a period of imperialist expansion in Egypt, South Africa, and elsewhere. Canada, Australia, and New Zealand became self-governing dominions.

Question: Which war caused Britain to lose some of its oldest and most populous colonies?
Ans: American War of Independence


Article: A similar fate befell the Curonians who lived in the area around the Curonian Lagoon. While many fled from the Red Army during the evacuation of East Prussia, Curonians that remained behind were subsequently expelled by the Soviet Union. Only 219 lived along the Curonian Spit in 1955. Many had German names such as Fritz or Hans, a cause for anti-German discrimination. The Soviet authorities considered the Curonians fascists. Because of this discrimination, many immigrated to West Germany in 1958, where the majority of Curonians now live.

Question: Where did most of the Curonians flee to in 1958?
Ans:
West Germany
