Input: Question: How many NCAA tournament titles has the coach for the only college basketball team to have ever had its national title vacated won? Passage 1:At the time, the term "Southern Syria" referred to a political position which implied support for the Greater Syria nationalism associated with the kingdom promised to the Hashemites of the Hejaz by the British during World War I. After the war, the Hashemite prince Faisal attempted to establish such a Pan-Syrian or pan-Mashriq state (i.e. a united kingdom that would comprise all of modern Syria, as well as Mount Lebanon and Palestine, including Transjordan, so that Palestine would be the province of "Southern Syria"). This kingdom was to be united with the other Hashemite domains in Hejaz and Iraq, thus contributing in large measure towards the fulfillment of Pan-Arabist ambitions. However, he was stymied by conflicting promises made by the British to different parties (see Sykes–Picot Agreement, Balfour Declaration and McMahon–Hussein Correspondence), leading to the Franco-Syrian War, which destroyed the Arab Kingdom of Syria in 1920.
 Passage 2:The first NCAA Tournament was organized by the National Association of Basketball Coaches. Oregon won the inaugural tournament, defeating Ohio State 46–33 in the first championship game. Before the 1941 tournament, control of the event was given to the NCAA. In the early years of the tournament, it was considered less important than the National Invitation Tournament (NIT), a New York City-based event. Teams were able to compete in both events in the same year, and three of those that did so—Utah in 1944, Kentucky in 1949, and City College of New York (CCNY) in 1950—won the NCAA Tournament. The 1949–50 CCNY team won both tournaments (defeating Bradley in both finals), and is the only college basketball team to accomplish this feat. By the mid-1950s, the NCAA Tournament became the more prestigious of the two events, and in 1971 the NCAA barred universities from playing in other tournaments, such as the NIT, if they were invited to the NCAA Tournament. The 2013 championship won by Louisville was the first men's basketball national title to ever be vacated by the NCAA after the school and its coach at the time, Rick Pitino, were implicated in a 2015 sex scandal involving recruits.
 Passage 3: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.
