Q: Question: How many years were there between the end of the British Burma Campaign and the start of the Battle of Na San? Passage:The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Nà Sản, at which the Viet Minh were defeated. The French used the lessons learned at Nà Sản – strong ground bases, versatile air support, and a model based on the British Burma Campaign – as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".

Q: Question: What was the final score in the loss to the Houston Rockets on March 30? Passage:On December 8, 2017, the Phoenix Suns signed House to a two-way contract with the team. Throughout the rest of the season, House would split his playing time there between Phoenix and their NBA G League squad, the Northern Arizona Suns. House would make his debut with the team a day later, scoring two points and recording a single rebound in 11 minutes of play in a close loss against the San Antonio Spurs. On December 16, House would score a season-high 8 points in 15 minutes of playing time in a 108–106 win over the Minnesota Timberwolves. House was later assigned to the Northern Arizona Suns affiliate alongside Davon Reed on December 28, mainly for healing purposes. House then returned to action on January 5, 2018, recording what was at the time a new season-high 9 points in a loss against the San Antonio Spurs. On February 23, his two-way contract expired, meaning he couldn't be allowed to play for Phoenix again until after the NBA G League's first season under its rebranded name concluded. Once that happened, he was allowed to return to Phoenix for the rest of the season. On March 30, House recorded a career-high 8 rebounds in a heartbreaking, buzzer-beating loss against the Houston Rockets. On April 1, House would record a new season-high with 16 points scored alongside 6 rebounds and 3 assists in a 117–107 loss against the Golden State Warriors. Two days later, House recorded 14 points, 6 rebounds, and a career-high 5 assists in a 97–94 win against the Sacramento Kings. On April 6, House would put up his first start in the NBA against the New Orleans Pelicans. Two days later, House would record career-highs of 22 points and 8 rebounds in a 117–100 loss to the Golden State Warriors.

Q: Question: Which continent where the 420 class racing vessels are popular currently has the larger population? Passage:Yachting has a long and prolific history in the area. New Silver Anchorage was dredged from Wild Harbor in the 1920s to shelter Beetle Cat boats which had become popular among the Cape Cod elite. Prior to the Second World War organized sailing flourished out of Wild Harbor, however U-Boat hysteria during the war led to dwindling popularity. On August 30, 1953, the Wild Harbor Yacht Club was formed on Wickertree Road to primarily serve New Silver and its constituent communities. The Club was incorporated by the United States Sailing Association the following year. A Widgeon fleet was organized in 1979 which brought the sport of sailing back into regional popularity. The club clinched the Southern Massachusetts Beetle Cat championship in 1981, 1982, 1984, 1985, 1986, 1987, and 1989. In 1990 the club focused its junior sailing on the new 420 class racing vessels which were already popular in Europe and Australia. Wild Harbor is a regional powerhouse and dominates the north shore of Buzzards Bay and competes competitively in the Southern Massachusetts Sailing Grand Prix. Wild Harbor has produced three collegiate all-Americans and a member of the 2000 US International 470 team.
