Question: Which of Eugenio's cousins in the first degree reigned longer with their respective titles? Passage:In addition to being a cousin in the first degree of Victor Amadeus III of Sardinia and of Louis Joseph of Bourbon, Prince de Conde, Eugenio's sister Maria Teresa (1749-1792) had married Louis Alexandre de Bourbon, Prince de Lamballe, the heir of a legitimised branch of the French royal family when he was 13, and had become the close friend and Surintendante of the French queen, Marie Antoinette of Austria, by 1775. As his elder brother, Victor Amadeus, was heir to the Carignano princedom, the traditional occupations for a younger son of a princely house, an episcopal or military sinecure, beckoned him to the French court. Upon reaching adulthood, he assumed a family title, Count of Villafranca, and obtained a commission in the French army service as proprietary colonel of the Villefranche Regiment, and was known there as "Prince Eugene, comte de Villefranche".

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.

Question: Which of the two leagues whose teams faced off in the 1924 World Series has won the competition more times? Passage:The 1924 World Series was the championship series of the 1924 Major League Baseball season. A best-of-seven playoff, the series was played between the American League (AL) pennant winner Washington Senators and the National League (NL) pennant winner New York Giants. The Senators defeated the Giants in seven games to win their first championship in club history. The Giants became the first team to play in four consecutive World Series, winning in 19211922 and losing in 19231924. Their long-time manager, John McGraw, made his ninth and final World Series appearance in 1924. The contest concluded with the second World Series-deciding game which ran to extra innings (the first had occurred in 1912). Later, the Senators would reorganize as the Minnesota Twins, again winning the World Series in 1987 and in 1991.
