Question: Which of the actors playing Qatermass and Paterson was younger? Passage 1:Born in Philadelphia, Day studied at the Jacobs School of Music at Indiana University and at the Curtis Institute of Music where she was a pupil of Margaret Harshaw. She placed third in the finals of the Metropolitan Opera National Council Auditions in 1973, which led to her debut performance at the Metropolitan Opera House on March 25, 1973 singing "Come scoglio" from Cosi fan tutte and "Song to the Moon" from Rusalka. She made her professional opera debut in 1972 with the Pennsylvania Opera Company as Violetta in La traviata. That same year she was the soprano soloist in Verdi's Requiem with the Mendelssohn Club. In 1973 she portrayed Mimi in La boheme and Violetta with the Little Lyric Opera Company in Philadelphia.

Isla Blair was cast as Home Secretary Margaret Blaker, a combination of parts of Lomax's character and two officials from the original serial, and she brought to rehearsals a photograph of her husband Julian Glover on the set of the 1967 film version of Quatermass and the Pit. Blair stated that she was delighted to be joining "the Quatermass club".
Passage 3:The conflict emerged from the First Indochina War against the communist-led Viet Minh. Most of the funding for the French war effort was provided by the U.S. After the French quit Indochina in 1954, the US assumed financial and military support for the South Vietnamese state. The Viet Cong, also known as or NLF (the National Liberation Front), a South Vietnamese common front under the direction of North Vietnam, initiated a guerrilla war in the south. North Vietnam had also invaded Laos in the mid-1950s in support of insurgents, establishing the Ho Chi Minh Trail to supply and reinforce the Viet Cong. U.S. involvement escalated under President John F. Kennedy through the MAAG program from just under a thousand military advisors in 1959 to 16,000 in 1963. By 1963, the North Vietnamese had sent 40,000 soldiers to fight in South Vietnam. North Vietnam was heavily backed by the USSR and the People's Republic of China. China also sent hundreds of PLA servicemen to North Vietnam to serve in air-defense and support roles.

Question: Was the GDP of Egypt larger than that of Syria the year of the Israeli invasion into Lebanon? Passage 1:PA 741 begins at an intersection with PA 722 in the borough of East Petersburg in Lancaster County, heading to the south on two-lane undivided Lemon Street, which is unsigned and locally maintained. The road passes homes prior to crossing into East Hempfield Township, where it becomes Rohrerstown Road and continues through industrial parks. PA 741 gains a center left-turn lane and becomes signed at the Commercial Avenue intersection. The route continues to an interchange with PA 283, at which point it becomes state-maintained. The road crosses the Little Conestoga Creek into Manheim Township after PA 283. The route becomes two lanes again and turns east prior to turning southwest and crossing the Little Conestoga Creek back into East Hempfield Township. At this point, PA 741 becomes McGovernville Road and comes to a bridge over Norfolk Southern's Lititz Secondary and Amtrak's Keystone Corridor. The road passes a mix of homes and woods as it comes to the Harrisburg Pike intersection, where it makes a turn to the south onto Rohrerstown Road, a three lane road with a center left-turn lane. PA 741 passes homes to the west and a branch of Lancaster General Hospital to the east prior to coming to the US 30 interchange. In the area of the interchange, PA 741 is briefly a divided highway. Following US 30, the route becomes a two-lane undivided road and passes residences prior to crossing Norfolk Southern's Columbia Secondary and entering the residential and commercial community of Rohrerstown. Here, PA 741 crosses PA 23. After leaving Rohrerstown, the road passes a mix of farms and businesses prior to an intersection with PA 462.
Passage 2:Blignaut went to the State School in his birthplace Paarl, where he subsequently attended the Gymnasium (Grammar School). After his exams Blignaut went to Cape Town, where he joined the colonial administration. In 1861 he passed the examination for the State Service Certificate of the Cape Colony and in 1862 he moved to the Orange Free State. Here he was appointed to the position of clerk to the Landdrost and Justice of the Peace of Philippolis (17 September 1862). At the time, civil, judicial, and military administration were still very much in the same hand. In view of Basotho threats, President Brand ordered the reorganisation of the Orange Free State defence, and the formulation of clear regulations for the different Volunteer Corps, which were administered by the Landdrosts' offices. For Philippolis Blignaut and J.G. Fraser attended the conference.
Passage 3:According to historians William Cleveland and Martin Bunton, Beirut became an international banking center because of its "laissez-faire economic system". Business owners from Cairo, Damascus, and Baghdad moved to Beirut for economic opportunities. Despite Lebanon's cultural liberalism and economic prosperity, sectarian tensions remained as citizens identified themselves through their sects. With Muslims calling for greater representation and with Cold War tensions, Lebanese leadership had to decide whether to ally with the West or with Egypt, Syria and its Arab history. Christians wanted to continue alliances with the West but Muslims were drawn to Nasser's pan-Arabism. Multiple factors including sectarian tensions and Palestinian refugee settlement in southern Lebanon contributed to the beginnings of the Lebanese Civil War. In 1976, Syrian President Hafez al-Assad sent troops into Lebanon to fight PLO forces on behalf of Christian militias. This led to escalated fighting until a cease-fire agreement later that year that allowed for the stationing of Syrian troops within Lebanon. The Syrian presence in Lebanon quickly changed sides; soon after they entered Lebanon they had flip-flopped and began to fight the Christian nationalists in Lebanon they allegedly entered the country to protect. The Kateab Party and the Lebanese Forces under Bachir Gemayel strongly resisted the Syrians in Lebanon. Following the Israeli invasion into Lebanon in 1982, new Lebanese President Amine Gemayel sought the support of Syrian troops to stabilize the region. Syria fought Israeli troops after the latter's invasion of Lebanon.

Question: What year did the Toshitsugu descendants stop ruling over Toyama castle? Passage 1:One of the later signings of the summer was goalkeeper Len Hill, who joined from Queens Park Rangers in June 1925. Regular keeper Tommy Allen had turned down a new contract at the club, leading to the signing of Hill as his replacement. Allen later agreed to new terms in October and returned to his place as first-choice Southampton goalkeeper, with Hill making sporadic appearances later in the season. Transfer activity continued throughout the season. In December 1925 the club signed inside-forward Jim Swinden from Salisbury City, following a trial in which he scored two goals on his debut for the reserve side against Folkestone. In March 1926, right-half Bill Adams joined from Southern League side Guildford United. Needing money to purchase the freehold of The Dell, Southampton sold mainstay full-backs Fred Titmuss and Tom Parker in early 1926 the former in February to Plymouth Argyle for 1,750; the latter in March to Arsenal for 3,250 which "caused uproar amongst supporters".
Passage 2:In late April 2016, Travis began taking part in extended spring training games. He was assigned to the Advanced-A Dunedin Blue Jays for rehab on May 13. On May 18, he was promoted to the Triple-A Buffalo Bisons to continue rehabbing. On May 25, Travis was activated off the disabled list by the Blue Jays and called up. He hit a walk-off infield single on May 28 to help the Blue Jays defeat the Boston Red Sox 109. On August 5, Travis hit two home runs in a game for the first time in his career. Leading off against the Kansas City Royals, Travis hit a solo home run to give the Blue Jays an early 10 lead. In the ninth inning, he hit another solo home run off Kelvin Herrera to lift Toronto to a 43 victory. On August 8, Travis hit his first career triple, which came as part of a four-hit game against the Tampa Bay Rays. Following a game on August 31, the Blue Jays optioned Travis to the Rookie-Advanced Bluefield Blue Jays. The move was made to allow Josh Thole to be re-signed and have postseason eligibility. As the Bluefield season would end on September 1, Travis could be immediately recalled by Toronto afterward, bypassing the ten-day waiting period. Travis was recalled by the Blue Jays on September 2. He finished the season hitting .300 with 11 home runs and 50 RBI in 101 games. Travis played in the Wild Card Game and the first game of the American League Division Series, but missed the remainder of the ALDS with a bone bruise in his right knee. He played in the first game of the Championship Series, but left in the fifth inning after reaggravating his knee injury. On October 15, Travis was removed from the ALCS roster due to injury, and replaced by Justin Smoak. In accordance with MLB rules, Travis was ruled ineligible to return for the postseason, ending his season. On November 18, he underwent right knee surgery to remove a small flap of cartilage, and was expected to be ready for spring training.
Passage 3:Following the establishment of the Tokugawa shogunate, the Maeda clan were confirmed as daimyo of Kaga Domain, which included most of Etchu Province. Maeda Toshinaga, the son of Maeda Toshiba and second daimyo of Kaga Domain rebuilt the castle and temporarily used it as his retirement home until much of it burned down in 1609. His grandson, Maeda Toshitsugu was awarded a 100,000 koku holding in Etchu Province in 1639, the forming Toyama Domain; however, initially his fief did not include Toyama Castle. Unable to raise funds to build his own castle, in 1659 he reached an agreement with Kaga Domain to exchange some of holdings for Toyama Castle and the surrounding lands. In 1661, he received permission from the Tokugawa shogunate to rebuild the castle and to lay out a new castle town. His descendants ruled over Toyama from here until the Meiji Restoration. Many of the structures of the castle and its rampant were destroyed by the 1858 Hietsu earthquake, and most of what survived was destroyed by order of the new Meiji government in 1871.
