Passage 1:On April 1942, when the 24th Tank Corps was formed, Burdeinei joined it as chief of staff to General Badanov. The Corps was sent to engage the advancing German forces in the South, and was nearly wiped out in the fighting near the Don River, during July. By late October, the unit has recovered from its losses after several months in the reserve. It was assigned to the Southwestern Front and took part in the Battle of Stalingrad. On December, the Corps destroyed the Tatsinskaya Airport and was renamed 2nd Tatsinskaya Guards Tank Corps in honor of this operation. After the Battle of Stalingrad the Corps was made part of the Voronezh Front on March. On 26 June 1943, Colonel Burdeinei assumed command over the Corps, holding the post to the end of the war. As such, he participated in the Battle of Kursk, and was promoted to Major General on 31 August. On 3 July 1944, during Operation Bagration, his units were the first to enter Minsk and liberated the city. He was promoted to the rank of Lieutenant General on the 2 November 1944. The Corps later took part in the Baltic, East Prussian, Vistula-Oder and Berlin operations. For his leadership during the Minsk Offensive he was awarded the title Hero of the Soviet Union (Medal no. 5026) on 19 April 1945.
 Passage 2:In 1600, the family were granted the Earldom of Winton and the 1st Earl immediately set about restoration of the castle, although work ceased upon his death in 1603. His son Robert, the 2nd Earl, resigned the title which passed to his younger brother George. George commissioned William Wallace, master-mason to the king, to oversee the completion of the restoration in 1620. One of the plasterers who made the fine ceilings was John White or "Quhyte", who also worked for Lady Home at The Hirsel. White was killed at Dunglass Castle when it was destroyed by an explosion in August 1640. The completed house was more palatial than defensive, in keeping with a new confidence after the turbulent 16th century. Prince Charles, the future King Charles I of Scotland and England, was said to have visited Winton House, having been tutored by Alexander Seton, 1st Earl of Dunfermline who resided at nearby Pinkie House. Charles' son, King Charles II also visited the house. 
 Passage 3:After graduating from the Yale School of Drama, Clarkson was cast in a 1986 Broadway production of The House of Blue Leaves as a replacement in the role of Corrinna Stroller. The following year, she made her feature film debut in Brian De Palma's The Untouchables (1987), portraying Catherine Ness, the wife of US Treasury Prohibition agent Elliott Ness (Kevin Costner). Clarkson stated she was financially struggling during this time and was paying student loans, and that De Palma expanded her role in the film as she originally only had several days' worth of shooting. The next year, she was cast in Clint Eastwood's The Dead Pool (1988), the fifth installment in the Dirty Harry film series. In 1989, she returned to Broadway portraying a Wall Street investment counselor whose brother (played by Kevin Conroy) is diagnosed with AIDS; the play ran from January to March of that year. Clarkson has stated that beginning in the early 1990s, she went through a turbulent period in her career and was unable to find significant work.

Her performance earned her an Independent Spirit Award nomination for Best Supporting Actress.
