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: What car did Sommer drive in the Vanderbilt Cup? Passage:Sommer was born in Mouzon, in the Ardennes departement of France, into a wealthy Sedan carpet-making family. His father, Roger Sommer, broke the Wright Brothers' record for the longest flight in 1909. It was not until 1931 that Raymond started to display daredevil tendencies of his own, entering motor races in a privateer Chrysler Imperial. The following year, he won the 24 Hours of Le Mans race, despite having to drive over 20 hours solo after his teammate, Luigi Chinetti, retired ill. During the 1930s, Sommer was to dominate the French endurance classic, winning again in 1933 driving an Alfa Romeo alongside Tazio Nuvolari. He also led every race until 1938, only to suffer a mechanical failure, once when 12 laps in the lead. Sommer traveled to Long Island, New York, to compete in the 1936 Vanderbilt Cup where he finished fourth behind the winner, Nuvolari.

Question: What age was Mary J. Blige when Rolling Stone called her debut album "genre-creating"? Passage:American singer and songwriter Mary J. Blige began her career as a backing vocalist for Uptown Records in the early 1990s. She has released 13 studio albums, eight of which have individually achieved worldwide multi-platinum status. The Queen of Hip-Hop Soul and Queen of R&B (publications often refer to her as both honorific titles), Mary J. Blige is uniquely credited as the first singer to release an album singing over hip-hop beats, which created the genre "hip hop soul" which fuses elements of soul, R&B and gospel style vocals over hip hop beats. Blige's genre-changing sound, in many ways, changed and shaped the sound for modern day R&B and blue-eyed soul artists. In September 1999, Rolling Stone bestowed her first album, What's the 411? (1992), as "genre-creating". Her discography consists of 14 top 10 Billboard 200 studio albums, two live albums, two remix albums and over eighty singlesincluding more than 20 as a featured artist. In 2009, Billboard magazine ranked Blige as the most successful female R&B/hip-hop artist of the past 25 years. In March 2017, Billboard magazine ranked her 2006 song "Be Without You" as the most successful R&B/hip-hop song of all time, as it spent an unparalleled 75 weeks on the Hot R&B/Hip-Hop Songs chart, 15 of those weeks at number one. In 2011, VH1 ranked Blige as the 80th greatest artist of all time. Moreover, she was ranked 100th on the list of "100 Greatest Singers of All Time" by Rolling Stone magazine. In 2012, VH1 ranked Blige ninth among "The 100 Greatest Woman in Music" listing.
