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.

Q: Question: When did the war end that brought the inhabitants of New Mexico under the governance of the United States? Passage:Hispanos identify strongly with their Spanish heritage and most are also mestizos of mixed Apache, Comanche, Pueblo, Navajo, Native Mexican, and Genízaro ancestry. Exact numbers for the population size of New Mexican Hispanos is difficult, as many also identify with Chicano and Mexican-American movements. For most of its modern history, New Mexico existed on the periphery of the Spanish empire from 1598 until 1821 and later Mexico (1821–1848), but was dominated by Comancheria politically and economically from the 1750s to 1850s. Due to the Comanche, contact with the rest of Spanish America was limited, and New Mexican Spanish developed closer trading links with the Comanche than the rest of New Spain. In the meantime, some Spanish colonists coexisted with and intermarried with Puebloan peoples and Navajos, enemies of the Comanche. New Mexicans of all ethnicities were commonly enslaved by the Comanche and Apache of Apacheria, while Native New Mexicans were commonly enslaved and adopted Spanish language and culture. These Genízaros served as house servants, sheep herders, and in other capacities in New Mexico including what is known today as Southern Colorado well into the 1800s. By the late 18th century, Genízaros and their descendants, often referred to as Coyotes, comprised nearly one-third of the entire population of New Mexico. After the Mexican–American War, New Mexico and all its inhabitants came under the governance of the English-speaking United States, and for the next hundred years, English-speakers increased in number. By the 1980s, more and more Hispanos were using English instead of New Mexican Spanish at home.

Q: Question: How many of Colton's teammates for the 2018-19 curling season are married? Passage:After joining the Edmonton based team of Kevin Koe, B. J. Neufeld and Ben Hebert, his new team began the 2018-19 curling season by winning the first leg of the Curling World Cup, defeating Norway's Steffen Walstad in the final. In provincial playdowns, the Koe rink lost two of their first three games at the 2019 Boston Pizza Cup, before winning five straight games to claim the Alberta championship. The team represented Alberta at the 2019 Tim Hortons Brier, and went undefeated in the entire tournament en route to winning his first Brier title. They went on to represent Canada at the 2019 World Men's Curling Championship, finishing the round robin with a 9-3 record. They battled through the playoffs to play Team Sweden's Niklas Edin rink in the final, losing 7-2. In Grand Slam play, the team failed to win any slams, but did make it to three finals. Despite the lack of any event wins, their strong play was good enough to award them with the Pinty's Cup for the season's best Slam team. The team ended the season in the Grand Final of the Curling World Cup, where they beat the host Chinese team (Zou Qiang). At the end of the season, Team Koe ranked first on the World Curling Tour Order of Merit and Money List. This also meant they led the CTRS standings, finishing the season with 512.335 points.
