[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: What team did Neil Ramirez play for when Bellinger hit his first major league hit off of him? Passage 1:In 1923 it was organised the first edition of leagues in the Kingdom of Yugoslavia where, beside the top-level national Yugoslav Football Championship, regional championships were also played. The clubs of the Drina Banovina, part of Littoral Banovina and Vrbas Banovina, territorially similar to present day Bosnia and Herzegovina, played within the Sarajevo Football Subassociation League until 1939. The champions of Subassociation Leagues were granted a place in the qualifiers to the Yugoslav Championship, a top national level. SASK (1923, 1924, 1925, 1926, 1927, 1928, 1930/31), Slavija (1929, 1930, 1932/33, 1934/35, 1935/36, 1936/37, 1937/38, 1938/39, 1939/40), FK Krajisnik Banja Luka (1935/36) were the clubs to manage to participate in the national league, first in 1923 when the championship was played in a cup system. In 1939 the Yugoslav league system was changed, with the creation of separate Serbian and Croato-Slovenian Leagues which will serve as qualifying leagues for the final phase of the Yugoslav Championship. The clubs from the Sarajevo Subassociation played their qualifications to the Serbian League, however Slavija Sarajevo managed to participate, in 193940 (3rd place) and 194041 (9th place) and played their qualifications to the Croatian-Slovenian League, however SASK managed to participate, and it did it in both occasions, in 193940 (5th place) and 194041 (5th place). That became the last season before the beginning of the Second World War.
Passage 2:Bellinger started in left field in his major league debut on April 25, 2017, against the San Francisco Giants, and had one hit in three at-bats, with an intentional walk. He was just the third Dodgers player in history to be intentionally walked in his debut (Chico Fernandez, Dick Nen). Bellinger's first major league hit was an infield single off Neil Ramirez in the ninth inning of the same game. Bellinger hit his first major league home run on April 29 off Zach Eflin of the Philadelphia Phillies and followed that by hitting a second home run in the same game, this one off Hector Neris. He was just the third Dodgers player with a twohome-run game among his first five starts, joining Charlie Gilbert (1940) and Yasiel Puig (2013). He hit his first grand slam on May 6, off Miguel Diaz of the San Diego Padres, as part of a career-high five RBI day. He was the first Dodgers player to hit five home runs within his first 11 games. Bellinger was named the National League Player of the Week for the first week of May. With nine home runs in May, Bellinger moved into a three-way tie with Joc Pederson (May 2015) and James Loney (September 2007) for most home runs by a Dodgers rookie in a calendar month. He was named the National League Rookie of the Month for May.
Passage 3:As part of Middle Tennessee, Grundy County has historically been one of the strongest Democratic counties in the state. It voted Democratic in every presidential election from 1912 to 2004, except for in 1968 (when segregationist George Wallace won the county), and 1972 when many traditional Democratic voters around the nation rejected the perceived radical liberal George McGovern in favor of incumbent Republican Richard Nixon. However, like most of the rural south, Grundy County has shifted towards the Republican Party in recent years, but was one of the last counties in Tennessee to make the switch to the party. The last Democratic Presidential candidate to win Grundy County was John Kerry in 2004, who won 18 out of Tennessee's 95 counties, whereas Al Gore won 36 in 2000. Grundy County was also won by Democratic U.S senate candidates Bob Clement in 2002 and Harold Ford Jr. in 2006, both of whom lost. Republican Presidential nominee John McCain won the county by nearly 13% in 2008, becoming the first Republican Presidential candidate to win Grundy County since Nixon won it 36 years earlier, and by 2016, Grundy County had taken a major shift toward the GOP, when Republican Donald Trump received 76% of the vote, a figure closer to what is usually seen in historically Republican East Tennessee counties.

[EX Q]: Question: When did the US enter the war that McNamara fought in as a sergeant of the 87th Division? Passage 1:Ahead of the club's first season in League One, Westley adopted the same "five in, five out" transfer policy as he had done for the two previous seasons. Strikers Yemi Odubade and Charlie Griffin were the first to leave having been loaned out for much of the previous campaign, joining Conference National sides Gateshead and Forest Green Rovers respectively. Second choice goalkeeper Ashley Bayes opted to leave the club in order to play first-team football at Conference South club Basingstoke Town. Luke Foster and David Bridges also opted to leave Stevenage ahead of the season, both on free transfers, with Foster signing for Rotherham United, and Bridges for his former club, Kettering Town. Stevenage's first signing of the season was striker Guy Madjo, who joined on a free transfer from Albanian Superliga side KS Bylis Ballsh. Former Stevenage goalkeeper Alan Julian re-joined the club following his release by Gillingham, while Phil Edwards rejected a contract extension at Accrington Stanley in order to join the Hertfordshire club on a free transfer. Midfielders Jennison Myrie-Williams and Robin Shroot also signed on free transfers following successful trial periods with the club. In terms of transfers during the 201112 campaign, striker Don Cowan joined the club from Longford Town for an undisclosed fee in August 2011, and winger Luke Freeman signed from Arsenal in January 2012, after a successful three-month loan spell with the club. Strikers Byron Harrison and Guy Madjo both departed in January 2012, signing for League Two sides AFC Wimbledon and Aldershot Town for respective undisclosed fees.
Passage 2:McNamara was a native of Fair Haven, Vermont, and attended the schools of Fair Haven. He graduated from College of the Holy Cross in 1915, studied law with a Vermont attorney, and attended Harvard Law School. Leaving law school early to enter the military for World War I, McNamara served in the United States Army and attained the rank of sergeant as a member of the 87th Division. After leaving the Army, McNamara was admitted to the bar and began to practice law in Burlington, Vermont. He became active in politics as a Democrat, and served as Burlington's municipal court judge from 1921 to 1923. After unsuccessful runs for Vermont Attorney General and the U.S. House, in 1933 McNamara was named US Attorney for Vermont. He held the post through the administrations of Democrats Franklin Roosevelt and Harry Truman, and resigned after Republican Dwight Eisenhower became president.
Passage 3:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the red-winged starling in his Ornithologie based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name Le merle du Cap de Bonne Esperance and the Latin Merula Capitis Bonae Spei. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the red-winged starling. Linnaeus included a brief description, coined the binomial name Turdus morio and cited Brisson's work. The specific name morio or morion is Latin for "dark brown stone" or "black quartz". This species is now placed in the genus Onychognathus that was introduced by the German physician and ornithologist Gustav Hartlaub in 1849.
