Question: 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 Na San, at which the Viet Minh were defeated. The French used the lessons learned at Na San 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".

He has degrees from Haverford College (A.B., 1963) and from Columbia University (M.A., 1964; Ph.D., 1970), where he studied under James L. Clifford, Allen T. Hazen, and John H. Middendorf. Between 1966 and 1971, while working on his dissertation on aspects of the 18th-century London book trade, he taught advanced prose composition courses at the Columbia University School of General Studies, an activity leading to the 1972 publication of The Art of Persuasion, a writing manual co-authored with J. Steward LaCasce. While in England on a Columbia traveling fellowship in 196869, he revised the book production sections of the 18th-century volume of the New Cambridge Bibliography of English Literature (NCBEL), working with Graham Pollard, who had compiled the original sections for the first edition of CBEL, published in 1940. With Jane Marla Robbins, he co-authored and co-directed a one-character play starring Robbins called Dear Nobody, based on the life of the 18th-century diarist and novelist, Fanny Burney. The play ran Off-Off-Broadway in 1968; it later had a five-months' Off-Broadway run at the Cherry Lane Theatre in 1974.

Question: Passage: On 7 October 1593, the superintendent of the Venetian Republic founded a revolutionary new kind of settlement: Palmanova. The city's founding date commemorated the victory of the Christian forces (supplied primarily by the Italian states and the Spanish kingdom) over the Ottoman Turks in the Battle of Lepanto in 1571, during the War of Cyprus. Also honored on 7 October was Saint Justina, chosen as the city's patron saint. Using all the latest military innovations of the 16th century, this small town was a fortress in the shape of a nine-pointed star, designed by Vincenzo Scamozzi. Between the points of the star, ramparts protruded so that the points could defend each other. A moat surrounded the town, and three large, guarded gates allowed entry. The construction of the first circle, with a total circumference of , took 30 years. Marcantonio Barbaro headed a group of Venetian noblemen in charge of building the town, Marcantonio Martinego was in charge of construction, and Giulio Savorgnan acted as an adviser. A second phase of construction took place between 1658 and 1690, and the outer line of fortifications was completed between 1806 and 1813 under the Napoleonic domination. The final fortress consists of: 9 ravelins, 9 bastions, 9 lunettes, and 18 cavaliers.
