Question: How many siblings did Khalid have in total? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Question: What other commercials did Rupert Sanders direct the year he directed The Life? Passage:The Life, also known as We Are ODST is a television and cinema advertisement launched in 2009 by Microsoft to promote the first person shooter  in the United States. The 150-second piece follows a young soldier through enlistment, training, and battle as an Orbital Drop Shock Trooper (ODST), analogous to a paratrooper that drops from space to a battlefield. The Life was created by advertising agency T.A.G., an offshoot of McCann Erickson. Production of the commercial itself was handled by production company Morton/Jankel/Zander (MJZ). It was directed by Rupert Sanders, and post-production was conducted by Asylum. It was filmed in Hungary, just outside Budapest in a coal mine and abandoned factories to give the sequence an "Eastern Bloc" aesthetic. The commercial and its associated campaign proved hugely successful; on the week of its launch, Halo 3: ODST became the top-selling game for the Xbox 360 worldwide, and over 2.5 million copies were sold within the first few weeks of release. The Life went on to win a number of honours from the advertising and entertainment industries, including two Clio Awards, a London International Advertising Award and several honours from the Cannes Lions International Advertising Festival, the most prestigious awards ceremony in the advertising industry.

Question: What county was the 73rd Regiment of Foot formed in? Passage:In April 1809 the regiment raised a second battalion in Nottingham from local militia companies and lost its Highland status due to recruiting difficulties, becoming the 73rd Regiment of Foot. The 1st Battalion embarked at Yarmouth for a seven-month journey to New South Wales, Australia in May 1809. The battalion's role was to ensure the newly appointed New South Wales Governor Lachlan Macquarie was able to govern after the previously appointed governor William Bligh was deposed by leading members of the New South Wales Corps (102nd Regiment of Foot) in the Rum Rebellion. There in 1810 they received a draft of men from the New South Wales Corps. The 73rd Regiment was under the command of Maurice Charles O'Connell who married Mary Putland, the widowed daughter of William Bligh in May 1810, which created ongoing tension with the leaders of the Rum Rebellion (such as John Macarthur) who were highly influential members of society within New South Wales. To reduce these tensions, the main body of the battalion left New South Wales in April 1814 on the General Hewitt for Ceylon. During the tour in Ceylon the battalion was under the command of Lieutenant Colonel Andrew Giels, whose children, along with hundreds of wounded men of the regiment, perished in May 1815 in the wreck of the Arniston after visiting him there.
