[EX Q]: Question: How long had the United Nations been in existence when Gross was appointed? Passage 1:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.
 Passage 2:In 1908, she met John Dailey de Angeli, a violinist, known as Dai. They were married in Toronto on April 12,1910. The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.
 Passage 3:The Tremp Basin evolved into a sedimentary depression with the break-up of Pangea and the spreading of the North American and Eurasian Plates in the Early Jurassic. Rifting between Africa and Europe in the Early Cretaceous created the isolated Iberian microplate, where the Tremp Basin was located in the northeastern corner in a back-arc basin tectonic regime. Between the middle Albian and early Cenomanian, a series of pull-apart basins developed, producing a local unconformity in the Tremp Basin. A first phase of tectonic compression commenced in the Cenomanian, lasting until the late Santonian, around 85 Ma, when Iberia started to rotate counterclockwise towards Europe, producing a series of piggyback basins in the southern Pre-Pyrenees. A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.

[EX Q]: Question: When was the school were Denean Howard and her 3 sisters set the National High School record in the 4x440 yard relay founded? Passage 1:The Tsardom of Russia had been experiencing the Time of Troubles (1598–1613) since the death of Tsar Feodor I in 1598, causing widespread political instability and a violent succession crisis for the title of Tsar of Russia by usurpers known as the False Dmitris. In 1605, the Polish-Muscovite War started when the Polish-Lithuanian Commonwealth unofficially invaded Russia in support of False Dmitry I against the unpopular crowned tsar Boris Godunov, seeking to exploit the country's weakness for their own gain. Godunov died in June 1605 and was replaced by False Dmitry I, whose popularity among the Russian populace declined rapidly during his reign, and the Polish withdrew when he was eventually murdered during an uprising in Moscow in May 1606. 
 Passage 2: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.
 Passage 3:Denean Howard and her 3 sisters gained fame in 1979 when the four of them teamed up to set the National High School record in the 4x440 yard relay for San Gorgonio High School in San Bernardino. That distance is now rarely run as the NFHS converted to metric distances, so the record still stands today. Later teams with Denean broke the record for the slightly shorter 4x400 metres relay, after sister Atra graduated and the rest of the family moved to Kennedy High School (Los Angeles). Denean was the California High School Athlete of the Year at Kennedy in 1982, following in the footsteps of her sister Sherri. Also following her sister, she was named the national Girl's "High School Athlete of the Year" by Track and Field News, two years in a row. Her 1982 52.39 was the NFHS national high school record for eighteen years, before it was beaten by Monique Henderson. At age 15, she qualified for the ill-fated 1980 U.S. Olympic Team which was part of the 1980 Olympic Boycott finishing behind sister Sherri at the 1980 Olympic Trials, the first sisters to make the Olympic team simultaneously in the same event.

[EX Q]: Question: Which opponent that the Cyber Sunday champions faced on Raw is the youngest? Passage 1:The main feud heading into Cyber Sunday was between WWE Champion John Cena, World Heavyweight Champion King Booker, and ECW World Champion The Big Show, the top champion of each of the three brands. This feud began on the October 9 edition of Raw, where they came face to face, arguing about who was the most dominant champion in WWE. WWE Chairman Vince McMahon interrupted, and booked a triple threat "Champion of Champions" match at Cyber Sunday between the three of them. This also gave each show's General Manager an opportunity to choose opponents for each other's champion that night. This resulted in Big Show defeating Jeff Hardy and Booker defeating Rob Van Dam; however, the match between Cena and The Undertaker was interrupted by Booker, Big Show, and The Undertaker's storyline rival, Mr. Kennedy. At the same time, Cena began a minor feud with Kevin Federline. Federline, as the on-screen close friend of Johnny Nitro and Melina's, appeared on Raw to promote his album, "Playing With Fire". Cena rapped about Federline, but Nitro came out to Federline's defense and was thrown out of the ring by Cena. Cena was then interrupted by his two Cyber Sunday opponents, and McMahon who announced that a championship would be on the line at Cyber Sunday. Cena performed the FU on Federline, after being insulted. The feud between the champions continued on the October 20 edition of SmackDown!, when Big Show and Cena were at ringside during Booker's title defense against Batista. Batista speared Booker onto Big Show, who, in response, assaulted Batista, ending the match via disqualification. Cena then joined the brawl, and SmackDown! General Manager Theodore Long announced a tag team match for the next week. On the next Raw, Cena defeated Nitro after an FU, but was assaulted afterwards by his Cyber Sunday opponents, who turned on each other shortly after to start a brawl between the four to end the show. Batista and Cena were successful in the tag team match, after Big Show abandoned Booker. The next week, on Raw, a preview of Cyber Sunday's interactivity was displayed when fans voted for Cena's opponent for the night, between Big Show, Booker, and Jonathan Coachman. Coachman won in the voting, but was easily defeated by Cena.
 Passage 2:Since its exposure in the news media of both France and Pakistan, the scandal has been involved in various investigative journalism and attracted sensations and conspiracy theories in both countries, including this scandal's allegement of financing the political campaign of then-Prime Minister Edouard Balladur in the presidential elections took place in 1995. Upon electing President Jacques Chirac cancelled the commissions and kickbacks, angering many officials in Pakistan and France according to the media reports. Other theories and subsequent investigative journalist reports alleged that the bus bombing on 8 May 2002 in Karachi that killed eleven French engineers in Karachi was in retaliation for the cancellation of these commissions. This theory was rejected by the Government of Pakistan when the FIA and the CID made potential discovery in linking the HuM and the al-Qaeda had carried out the terrorist attack in Karachi, mistaking the French nationals for the Americans.
 Passage 3:The One Hundred Eleventh United States Congress was a meeting of the legislative branch of the United States federal government from January 3, 2009, until January 3, 2011. It began during the last two weeks of the George W. Bush administration, with the remainder spanning the first two years of Barack Obama's presidency. It was composed of the Senate and the House of Representatives. The apportionment of seats in the House was based on the 2000 U.S. Census. In the November 4, 2008 elections, the Democratic Party increased its majorities in both chambers, giving President Obama a Democratic majority in the legislature for the first two years of his presidency. A new delegate seat was created for the Northern Mariana Islands. The 111th Congress had the most experienced members in history: at the start of the 111th Congress, the average member of the House had served 10.3 years, while the average Senator had served 13.4 years.
