[EX Q]: Question: Where was the person whose guard Yermolov served in 1807 born? Passage:His own military genius blossomed during the Napoleonic Wars. During the 1805 Campaign, Yermolov served in the rear and advance guards and distinguished himself at Amstetten and Austerlitz. For his actions, he was promoted to colonel on 16 July 1806. The following year, he participated in the campaign in Poland, serving in Prince Bagration's advance guard. He distinguished himself commanding an artillery company in numerous rearguard actions during the retreat to Landsberg as well as in the Battle of Eylau. In June 1807, Yermolov commanded horse artillery company in the actions at Guttstadt, Deppen, Heilsberg and Friedland, being awarded the Order of St. George (3rd class, 7 September 1807). He was promoted to major general on 28 March 1808 and was appointed inspector of horse artillery companies. In early 1809, he inspected artillery companies of the Army of the Danube. Although his division took part in the 1809 campaign against Austria, Yermolov commanded the reserves in Volhynia and Podolsk gubernias, where he remained for the next two years. In 1811, he took command of the guard artillery company and in 1812, became the Chief of Staff of the 1st Western Army.

[EX Q]: Question: Which PC operating environment sold more from Microsoft? Passage:Due to the sales growth of IBM clones in the '90s, they became the industry standard for business and home use. This growth was augmented by the introduction of Microsoft's Windows 3.0 operating environment in 1990, and followed by Windows 3.1 in 1992 and the Windows 95 operating system in 1995. The Macintosh was sent into a period of decline by these developments coupled with Apple's own inability to come up with a successor to the Macintosh operating system, and by 1996 Apple was almost bankrupt. In December 1996 Apple bought NeXT and in what has been described as a "reverse takeover", Steve Jobs returned to Apple in 1997. The NeXT purchase and Jobs' return brought Apple back to profitability, first with the release of Mac OS 8, a major new version of the operating system for Macintosh computers, and then with the PowerMac G3 and iMac computers for the professional and home markets. The iMac was notable for its transparent bondi blue casing in an ergonomic shape, as well as its discarding of legacy devices such as a floppy drive and serial ports in favor of Ethernet and USB connectivity. The iMac sold several million units and a subsequent model using a different form factor remains in production as of August 2017. In 2001 Mac OS X, the long-awaited "next generation" Mac OS based on the NeXT technologies was finally introduced by Apple, cementing its comeback.

[EX Q]: Question: How many people lived in Scone the year Wilshire first began serving as a clerk there? Passage:He was born in Sydney to James Robert Wilshire and Elizabeth Thompson, a member of a prominent and well-connected colonial family. He was educated at Peter Steel's School in Pitt Street and Henry Brown's City Grammar School before studying at the University of Sydney. He was a clerk and land agent at Scone from 1862. In 1883 he returned to Sydney, being now wealthy enough to retire. He was an alderman and mayor of Burwood, and was involved with a number of societies, notably those connected with sanitary reform. In 1889 he was elected to the New South Wales Legislative Assembly as one of the four Free Trade members for Canterbury, but he did not contest the 1891 election. Wilshire moved from Burwood to Neutral Bay, New South Wales in around 1894 (as did his half-brother Henry Austin Wilshire), and lived there until his death in 1909, leaving to his widow a substantial portfolio of local properties. He had no children.
