Question: Which of the battles and offensives that Kazakevich led were successful? Passage 1:Daniil Vasilievich Kazakevich (Russian: ; 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 PolishSoviet 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.
Passage 3:He was born in Brunswick to Congregationalist minister Abraham Isaac and Mary Judd. 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: Which driver who won the New Zealand Grand Prix in the Lola T332 car had the fastest lap time? Passage 1:The town was built on the mouth of a small tributary of the Severn Estuary near the mouth of the River Avon. The old pill or jetty provided protection for craft against the Bristol Channel's large tidal range, and iron rings can be seen in the high street at which fishing boats used to moor. Its position meant Portishead was used to guard the "King Road", as the waters around the headland are called. In 1497 it was the departure point for John Cabot on the Matthew. A fort was built on Battery Point, and was used during the English Civil War when the town supported the Royalists, but surrendered to Fairfax in 1645. Guns were also placed at Battery Point during World War II. The King Road was the site of a naval action in 1758 when HMS Antelope captured HMS Belliqueux, one of a French squadron returning from Quebec.
Passage 2:The T332 dominated the last three years of the US F5000 championship, with Briton Brian Redman taking the title three times in a row in 197476, his most serious rivals Al Unser and Mario Andretti, in 197475 in Parnelli T332C. Australian driver Warwick Brown used a T332 to win the 1975 Tasman Series as well as the 1975 New Zealand Grand Prix. In doing so he became the only Australian driver to ever win the Tasman Series. New Zealand driver Ken Smith also used a Lola T332 to win the 1976 New Zealand Grand Prix. Ken Smith had obtained Redman's 1974 US winning chassis and a couple of extremely powerful US F5000 chev engines. Lawrence, after a serious accident in the 72 NZGP regained competitive form in a new T332 in the 1974 Tasman and by 1975 had upgraded his chassis to the specs of Andretti's US car and running with real sponsorship from Malboro, Singapore Airlines and Wix, was Warwick Brown's most serious rival during the 1975 Tasman. As a side note, both the 1975 and 1976 New Zealand Grands Prix were held at Pukekohe Park Raceway. It was generally thought in the 1975 Tasman the two best drivers, Graham MacRae in a MacRae GM2 and Chris Amon in a Talon (a modified version of the GM2) were very much at a disadvantage compared with Lawrence, Brown and Smith in the Lola 332T, although to some extent that was compensated by the very fast Firestone F5000 tyres used by McRae for the last time in NZ which meant MacRae took pole or deadheated for pole time in the four kiwi rounds of the last Tasman. MacRae himself found his own T332 far faster than his GM2 in the 1974/75 US Travellers Cheque F5000 series. Although not able to equal the engine preparation of the Haas or Parnelli teams running at F1 level, even in 1975 at Watkins Geln, Lagua Seca and Long Beach, McRae in a T332 was still as quick as Jarier or Unser while his T332 lasted. In Australasia the T400 never matched the T332 although after its disastrous 1975 series, Max Stewarts T400 was often competitive in 1976 and 1977. In the Shellsport F5000 series in 1975, Peter Gethin and Pilete's T400 was probably quicker than the best T332s of Guy Edwards and Ian Ashley and in 1976 Keith Holland in a T400 often matched Edward's and David Purley 3.6 March and Chevron cars. The last two new T332c F5000s in 1977 were built for Alan Jones for the 1977 Australian Tasman rounds and Keith Holland Shellsport campaign that year.
Passage 3:The yellow bloodwood is found in central New South Wales from Howes Valley in the north to Tolwong in the south. Around the Sydney Basin, it is common on sandstone plateaux and escarpments in the vicinity of the Nepean and Hawkesbury Rivers, and lower Blue Mountains, particularly on western aspects of slopes. It is seen up to altitudes of 500 metres, with annual rainfall of 7301800mm. It grows in dry sclerophyll forest on sandstone soils, associated with such species as red bloodwood (Corymbia gummifera), dwarf apple (Angophora hispida), smooth-barked apple (Angophora costata), narrow-leaved stringybark (Eucalyptus sparsifolia), white stringybark (E. globoidea), sydney peppermint (E. piperita), grey gum (E. punctata), scribbly gums (E. haemastoma and E. racemosa) and black sheoak (Allocasuarina littoralis).

Question: What is the age difference between Ingold's parents? Passage 1:In 1938, after graduating from the Spetses school, Xenakis moved to Athens to prepare for entrance exams at the National Technical University of Athens. Although he intended to study architecture and engineering, he also took lessons in harmony and counterpoint with Aristotelis Koundouroff. In 1940 he successfully passed the exams, but his studies were cut short by the Greco-Italian War, which began with the Italian invasion on 28 October 1940. Although Greece eventually won the war, it was not long before the German army joined the Italians in the Battle of Greece, in April 1941. This led to the Axis occupation of Greece during World War II, which lasted until late 1944, when the Allies began their drive across Europe, forcing the Axis forces to withdraw. Xenakis joined the National Liberation Front early during the war, participating in mass protests and demonstrations, and later becoming part of armed resistancethis last step was a painful experience Xenakis refused to discuss until much later in life. After the Axis forces left, Churchill ordered that British forces step in to help restore the Greek monarchy; they were opposed by the Democratic Army of Greece, and the country plunged into a civil war. In December 1944, during the period of Churchill's martial law, Xenakis (who was by then a member of the communist students' company of the left-wing Lord Byron faction of ELAS) became involved in street fighting against British tanks. He was wounded and facially disfigured when shrapnel from a tank blast hit his cheek and left eye, which was blinded; that Xenakis survived the injury has been described as a miracle.
Passage 2:He was born to Sir Christopher Ingold and Dr. Hilda Usherwood, and studied for a BSc in Chemistry at the University of London, completing his degree in 1949. He continued his higher education with a PhD in chemistry at Oxford University, which he completed in 1951. Soon after graduation he moved to Canada to begin work with the National Research Council, followed by two years of post-doctoral research at the University of British Columbia. He returned to work for the NRC in 1955 as a research officer, followed by a promotion to head of the Free Radical Chemistry Section. He was awarded the 1968 Petroleum Chemistry Award, the 1988 Linus Pauling Award, and both the Davy Medal and Royal Medal of the Royal Society, the latter for "elucidating the mechanism of reactions involving free radicals". In 1995 he was made an officer of the Order of Canada. He has received honorary degrees from the universities of Guelph, Mount Allison, St Andrews, Carleton, McMaster and Dalhousie.
Passage 3:After college, Cranston began his acting career in local and regional theaters, getting his start at the Granada Theater in the San Fernando Valley. He had previously performed as a youth, but his show business parents had mixed feelings about their son being involved in the profession, so he did not continue until years later. Cranston was ordained as a minister by the Universal Life Church, and performed weddings for $150 a service to help with his income. He also worked as a waiter, night-shift security guard at the gates of a private LA community, truck loader, camera operator for a video dating service, and CCTV security guard at a supermarket. He started working regularly in the late 1980s, mostly doing minor roles and advertisements. He was an original cast member of the ABC soap opera Loving, where he played Douglas Donovan from 1983 to 1985. Cranston starred in the short-lived series Raising Miranda in 1988. Cranston's voice acting includes English dubbing of Japanese anime (for which he primarily used the non-union pseudonym Lee Stone), including Macross Plus and Armitage III: Poly-Matrix, and most notably, as Fei-Long, and the children's series Mighty Morphin Power Rangers. Cranston did voice work for the 1993-94 first season of that series, playing characters such as Twin Man and Snizzard, for which he was paid about $50 an hour for two or three hours of daily work. The Blue Power Ranger, Billy Cranston, was named for him.
