Question: Question: Which of the battles and offensives that Kazakevich led were successful? Passage 1:Daniil Vasilievich Kazakevich (Russian: Даниил Васильевич Казакевич; 16 December 1902 – 28 November 1988) was a Belorussian Soviet Lieutenant general and Hero of the Soviet Union. Kazakevich was drafted into the Red Army in 1920 and fought in the Polish–Soviet War. In 1923 he transferred to the Soviet Border Troops. Kazakevich became an officer and by 1939 was chief of staff of a border district in the Soviet Far East. In December 1942 he became chief of staff of the Far Eastern NKVD Rifle Division, which became the 102nd Rifle Division some months later. After fighting in Operation Kutuzov, Kazakevich was given command of the 399th Rifle Division in September 1943. Kazakevich led the division through the Battle of the Dnieper, Operation Bagration and the East Prussian Offensive. He was awarded the title Hero of the Soviet Union for his leadership in the battle for the Narew bridgeheads during September 1944. Postwar, Kazakevich returned to the Border Troops and led the Moldovan and Southwestern Border Districts. After a two-year period as an advisor to the East German Border Troops, Kazakevich became chief of the Border Troops military educational institutions. He retired in 1959 and lived in Moscow, working in the Intourist Directorate.
 Passage 2:In August 1915, after recovering from his injuries, Elles was one of three officers specially selected by General Sir William Robertson, soon to be Chief of the Imperial General Staff (CIGS), the professional head of the British Army, to liaise with troops at the front and pass the information directly to the British General Headquarters (GHQ). In January 1916, as a General Staff Officer (GSO), Elles was sent by General Sir Douglas Haig, the Commander-in-Chief (C-in-C) of the BEF on the Western Front, to investigate the first tanks or "caterpillars" being built in England. He attended the first trials of "Mother" and reported back to Haig on its success. During the summer of 1916, he was tasked to report back from the Somme, where the tanks were first used. Elles was appointed to head the Heavy Branch (the first tank units) of the Machine Gun Corps in France on 29 September 1916, with the temporary rank of colonel. His responsibilities included its advanced training and tactical employment. He also commanded the large central depot and workshops established near Bermicourt.

He attended state schools and became a schoolteacher, working for the Victorian Education Department from 1900. On 3 September 1907 he married Elizabeth Brown, with whom he had four children. In 1913 he was appointed a supervisor of school gardening, and pioneered several early initiatives in this area. During World War I he served with the 58th Battalion, and after the war he spent time in England studying horticulture. He ran a nursery at Noble Park from 1922. From 1928 to 1931 and 1937 to 1940 he was a member of Dandenong Shire Council, and he was also chairman of Associated Nurseries Pty Ltd from 1932 to 1965 and president of the Nurserymen and Seedsmen's Association from 1936 to 1937. In 1940 he was elected to the Victorian Legislative Council as a United Australia Party member for South Eastern Province. While in the Council he ran a Save the Forests campaign, which evolved into the National Resources Conservation League in which Isaac played a leading role. He lost Liberal and Country Party endorsement in 1952 and was defeated running as an independent candidate. In 1956 he was appointed an Officer of the Order of the British Empire. Isaac died at Footscray in 1965.

Question: Question: How long did the financial period last that delayed work on the park? Passage 1:Gary di Silvestri is a graduate of Monsignor Farrell High School in Staten Island, New York, where he was a member of the football, wrestling and track & field teams. He graduated salutatorian and was awarded the top student athlete on Staten island. He has an undergraduate degree from Georgetown University where he graduated Magna Cum Laude and was inducted into the Phi Beta Kappa National Honor Society. Gary also has a Masters of Business Administration from Columbia University, where he graduated with honors and was inducted into the Beta Gamma Sigma national honors society. He has had a long career in financial services, having worked for Credit Suisse First Boston in London, England; and Morgan Stanley in both London and New York City. In 1997, di Silvestri founded Deutsche Suisse Asset Management, and he said his business success had allowed him to pursue philanthropy full time. 
 Passage 2:On November 29, 2017, at 3 p.m., after playing “End Game” by Taylor Swift, WQMP flipped to alternative rock as Alt 101.9—joining several other former "AMP Radio"-branded stations in switching to the format and brand after the completion of the Entercom merger. The change brought the format back to a full-market signal in Orlando for the first time since 2008, when sister station WOCL flipped to classic hits. The most recent analog broadcast station to air the format full-time, Cox Media's W297BB/WCFB-HD2, was aired on a translator and an HD sub-channel, and aired from June 2014 to January 2016. Elsewhere in the Orlando market, iHeartMedia's talk-formatted WTKS-FM features alternative on nights and weekends, and is also aired on two HD subchannels in the Orlando market, WOCL HD2 and WJRR HD3, the latter of which also uses the brand Alt as standardized by iHeartMedia; this name conflict resulted in WQMP quietly changing its on-air brand to FM 101.9. WQMP's flip to alternative made former sister station WXXL the de facto CHR station in Orlando, until WPYO flipped to CHR from an urban-leaning rhythmic contemporary format in April 2018.
 Passage 3:A $2.5 million bond issue passed in 1922 for a stadium conceived by Burnham. Designed by architects Holabird & Roche and named Soldier Field for the veterans of World War I, cost overruns required another bond issue in 1926. By 1924, the breakwater wall stretched from 14th to 55th Streets. In 1926, Soldier Field and a portion of Lake Shore Drive were opened. Landfilling extended from 23rd Street to 56th Street; however, Promontory Point was not complete, prompting complaints regarding garbage, blowing sand and odors. Throughout the 1920s and 1930s, landfill efforts continued to fill in Burnham Park and the adjacent Northerly Island. The South Development was named for Daniel Burnham on January 14, 1927, and support increased for a world's fair in the park. Construction was completed on Lake Shore Drive, with northbound lanes named for Leif Erikson, and southbound lanes for Christopher Columbus. In 1929, construction of the park at Promontory Point began. The Great Depression delayed work and prevented construction of nearshore islands. Burnham Park was chosen for the site of the Century of Progress world's fair and a yacht basin was built south of 51st Street.

Question: Question: How many areas of study did Boston University offer degrees in the year Mairson began working there as a Visiting Professor? Passage 1:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".
 Passage 2:Mairson received a B.A. in Mathematics from Yale University in 1978 and a Ph.D. in Computer Science from Stanford University in 1984 under the supervision of Jeffrey Ullman.

Mairson was a Postdoctoral researcher at INRIA Rocqencourt from 1984 to 1985, at Stanford University in 1985, and at the University of Oxford in 1986. He held a Visiting Professor position from 1999 to 2001 at Boston University. From 2005 to 2007, Mairson has served as the Chair of the Faculty Senate at Brandeis.
