Question: How long did the war in which Massey joined the Canadian Army last? Passage 1:The Morris Brothers were born in Old Fort, North Carolina. Originally, they began performing as a trio together with a third brother, George Morris. In 1933, Zeke moved to Concord and joined J. E. Mainer's Crazy Mountaineers He made his first recordings with the Mountaineers in August 1935 för Bluebird Records. Four years later, in 1937, Wiley and Zeke along with banjo player Wade Mainer did some radio work in the North Carolina towns of Asheville and Raleigh. In April 1938, The Morris Brothers, fiddler Homer Sherrill and banjo player Joel Martin, calling themselves the Smilin' Rangers, performed at radio station WBTM in Danville, Virginia. In September 1938, Zeke recorded with Charlie Monroe as a replacement for Bill Monroe just after the Monroe Brothers had disbanded. The same year, Zeke's musical career came to a halt when he went to work in a cotton mill in Gastonia. In 1939, the brothers moved to Asheville and WWNC radio, where they resumed their career. After World War II they retired and opened an auto repair business. Between 1938 and 1939, the Morris Brothers made 36 recordings for RCA Victor.
 Passage 2:After leaving Union Station and crossing the Los Angeles River, the line follows the San Bernardino Freeway and El Monte Busway until just after the Cal State L.A. station; it then runs in the median of the San Bernardino Freeway to the El Monte Station along the former route of the Pacific Electric Railway's San Bernardino Line. Starting at El Monte, the line parallels the Union Pacific's Sunset Route (ex-Southern Pacific) for a few miles before turning northeast at Bassett onto a Southern Pacific branch. At (a former Southern Pacific/Pacific Electric-Santa Fe crossing), it switches to the Santa Fe; from Claremont to just west of San Bernardino it follows what was the Santa Fe's Pasadena Subdivision (and before that the Second District of the LA Division, the Santa Fe passenger main line). The San Bernardino Line is mostly single track with 6 passing sidings and short sections of double track near Covina, between Pomona and Montclair, and west of Fontana.
 Passage 3:Massey joined the Canadian Army at the outbreak of World War I, and served on the Western Front in the Royal Regiment of Canadian Artillery.

Question: What number President was Grover Cleveland before losing in 1888? Passage 1:Beginning with the 2000 election, the status of the Missouri bellwether came into question. Between 1904 and 2004, Missouri was carried by the victor of each presidential election, with the exception of 1956. Though Bush won the presidency in the 2000 election through the Electoral College, he lost the national popular vote. The 2000 election was unique because this was the first time in over a century where the popular vote winner lost the general election. (In 1888, Missouri voted for Grover Cleveland, the incumbent Democrat, who lost to Republican candidate Benjamin Harrison). Thus, controversy exists as to whether or not Missouri accurately predicted victor in this election. In the subsequent election, Missouri voted for George W. Bush, who this time won both the popular vote and the Electoral College. Missouri has voted reliably Republican since 2000. The state voted for John McCain in 2008, and for Mitt Romney in 2012, both of whom lost the general election to Barack Obama. The controversy is further complicated by the 2016 presidential election, where Missouri voted for Donald Trump by a landslide, while Hillary Clinton won the popular vote by nearly three million votes, but like in 2000, Trump won the Electoral College and became 45th President of the United States. Like 2000, political scientists have differing opinions on whether or not Missouri accurately predicted the victor, and even if Missouri is still a bellwether state at all.
 Passage 2:Minimal music is a form of art music that employs limited or minimal musical materials. In the Western art music tradition, the American composers La Monte Young, Terry Riley, Steve Reich, and Philip Glass are credited with being among the first to develop compositional techniques that exploit a minimal approach. It originated in the New York Downtown scene of the 1960s and was initially viewed as a form of experimental music called the New York Hypnotic School. As an aesthetic, it is marked by a non-narrative, non-teleological, and non-representational conception of a work in progress, and represents a new approach to the activity of listening to music by focusing on the internal processes of the music, which lack goals or motion toward those goals. Prominent features of the technique include consonant harmony, hypnotic rhythmic pulses or steady drones, stasis or gradual transformation, and often reiteration of musical phrases or smaller units such as figures, motifs, and cells. It may include features such as additive process and phase shifting. Phase-shifting leads to what has been termed phase music. Minimal compositions that rely heavily on process techniques that follow strict rules are usually described as process music.
 Passage 3:In 1950, Yost posted career-highs with a .295 batting average and a .440 on-base percentage. In 1951 he led the American League with 36 doubles and produced a career-high 65 runs batted in. He earned a place as a reserve player for the American League team in the 1952 All-Star Game. Between August 30, 1949 and May 11, 1955, Yost played in 829 consecutive games for the Senators, the ninth longest consecutive game streak in major league history. Yost's home run totals were diminished by having to play his home games in Washington's cavernous Griffith Stadium. Between 1944 and 1953, he hit only 3 home runs at home while hitting 52 home runs on the road.

Question: Is the game geared to doctors still in use today? Passage 1:3DiTeams was developed in collaboration with Duke University Medical Center and used for medical education and team training. The game is intended for training and exercising of medical teams of practitioners of many levels of clinical expertise. The scope of practice of the tools in the game are geared toward care of a trauma patient and the interpersonal communications that surround the patient's care. The training is based on the United States Department of Defense Patient Safety Program and Agency for Healthcare Research and Quality's TeamSTEPPS curriculum. In 2006, the Telemedicine and Advanced Technology Research Center (TATRC), a division of the United States Army Medical Research and Materiel Command, funded a one-year $249,530 award to support the "3DiTeams: Gaming Environment for Training Healthcare Team Coordination Skills" study. The team was also awarded a 2-year $291,248 grant from the NIH Agency for Healthcare Research and Quality for their study on "Virtual Health Care Environments Versus Traditional Interactive Team Training."
 Passage 2:In February 2017 a diplomatic committee led by former driver Eliseo Salazar began discussions with Formula E CEO Alejandro Agag in Buenos Aires about the possibility of holding a race in the Chilean capital of Santiago. The ePrix was officially confirmed by the world governing body of motorsport, the Fédération Internationale de l'Automobile (FIA), in June, and was added to the 2017–18 Formula E calendar by the FIA World Motor Sport Council three months later. It was the fourth of twelve scheduled single seater electric car races of the season and took place on 3 February 2018. Prior to the event, a non-championship Formula One race won by Juan Manuel Fangio was held on the streets of Santiago in 1950. The press predicted the ePrix would be the largest sporting event in Chile since the 1962 FIFA World Cup, and organisers expected 20,000 people in attendance.
 Passage 3:Crunchfish is a Swedish technology company in Malmö that develops gesture recognition software for the mobile phone and tablet market.
