[Q]: Passage: Landowski had not held any public office until his election to the Assembly's 13th Milwaukee County district (the 13th & 21st Wards of the city of Milwaukee) in 1948 to succeed fellow Democrat William Nawrocki, who was not a candidate for re-election. After getting an absolute majority in a four-way primary election race, he won in the general election with 10,912 votes to 6071 for Republican John Froemming and 250 for People's Progressive Leo Jacobs. He was assigned to the standing committee on transportation. After an easy victory in the 1950 primary, he again defeated Froemming in the general election. He remained on the transportation committee, and was also assigned to the committee on commerce and manufacturers. He was an unsuccessful candidate in 1952's spring election for the Milwaukee County board of supervisors.

[Q]: Passage: The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Nà Sản, at which the Viet Minh were defeated. The French used the lessons learned at Nà Sản – strong ground bases, versatile air support, and a model based on the British Burma Campaign – as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".

[Q]: Passage: The Romanoviches (Izyaslavichi of Volhynia)were the line of Roman the Great, descended from Mstislav I of Kiev through his son Iziaslav II of Kiev and his grandson Mstislav II of Kiev, father of Roman the Great. The older Monomakhovychi line that ruled Principality of Volhynia, they were eventually crowned kings of Galicia and Volhynia and ruled until 1323. Romanovychi displaced the older line of Izyaslavychi from Turov and Volhynia as well as Rostyslavychi from Galicia. The last were two brothers of Romanovychi, Andrew and Lev II, who ruled jointly and were slain trying to repel Mongol incursions. The Polish king, Władysław I the Elbow-high, in his letter to the Pope wrote with regret: "The two last Ruthenian kings, that had been firm shields for Poland from the Tatars, left this world and after their death Poland is directly under Tatar threat." Losing their leadership role, Rurikids, however, continued to play a vital role in the Grand Duchy of Lithuania and the later Polish-Lithuanian Commonwealth. Most notably, the Ostrogski family held the title of Grand Hetman of Lithuania and strove to preserve the Ruthenian language and Eastern Orthodoxy in this part of Europe. It is thought that the Drutsk and related princely families may also descend from Roman the Great.
