Question: How long had the Senator held his position before he helped Thurmond to try to get Schweiker off the ticket? Passage:In the 1976 Republican primary, President Ford faced a challenge from former California Governor Ronald Reagan, who selected Richard Schweiker as his running mate. Though Thurmond backed Reagan's candidacy, he, along with North Carolina Senator Jesse Helms, led efforts to oust Schweiker from the ticket. During the subsequent general election, Thurmond appeared in a campaign commercial for incumbent U.S. President Gerald Ford in his race against Thurmond's fellow Southerner, former Georgia Governor Jimmy Carter. In the commercial, Thurmond said Ford (who was born in Nebraska and spent most of his life in Michigan) "sound[ed] more like a Southerner than Jimmy Carter". After President-elect Carter nominated Theodore C. Sorensen as his choice to become Director of the Central Intelligence Agency, Thurmond expressed reservations and fellow Senator Jake Garn said he believed Thurmond would not vote for the nomination. Sorensen withdrew from consideration days later, before a vote could be had.
 Links: a. Jimmy Carter b. Director of the Central Intelligence Agency c. Jimmy Carter d. Jesse Helms

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.

Question: Who was the Han emperor when the Xianbei killed the Xiongnu chanyu Youliu? Passage:The Xianbei (; ) were an ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China. They originated from the Donghu people who splintered into the Wuhuan and Xianbei when they were defeated by the Xiongnu at the end of the 3rd century BC. The Xianbei were largely subordinate to larger nomadic powers and the Han dynasty until they gained prominence in 87 AD by killing the Xiongnu chanyu Youliu. However unlike the Xiongnu, the Xianbei political structure lacked the organization to pose a concerted challenge to the Chinese for most of their time as a nomadic people. After suffering several defeats by the end of the Three Kingdoms period, the Xianbei migrated south and settled in close proximity to Chinese society and submitted as vassals, being granted the titles of Dukes. As the Xianbei Murong, Tuoba and Duan tribes were one of the Five Barbarians who were vassals of the Han Chinese Western Jin and Eastern Jin dynasties, they took part in the Uprising of the Five Barbarians as allies of the Han Chinese Eastern Jin against the other four barbarians, the Xiongnu, Jie, Di and Qiang. The Xianbei were at one point all defeated and conquered by the Di Former Qin empire before it fell apart at the Battle of Fei River at the hands of the Eastern Jin. The Xianbei later founded their own states and reunited northern China as the Northern Wei. These states opposed and promoted sinicization at one point or another but trended towards the latter and had merged with the general Chinese population by the Tang dynasty.
 Links: a. Han dynasty b. Battle of Fei River c. Five Barbarians d. Eurasia
