Question: How long did Aulus Plautius live after capturing the lands south of the River Trent? Passage 1:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 4647 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
Passage 2:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frederic Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wullner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
Passage 3:Kevin Francis (born June 5, 1993) is a professional Canadian football linebacker for the Ottawa Redblacks of the Canadian Football League (CFL). After going undrafted in the 2016 NFL draft, Francis declared eligible for the 2016 CFL Supplemental Draft after informing the league that he was born in Toronto, Ontario. He was drafted by the Roughriders on May 26, 2016, who forfeited a third round selection in the 2017 CFL Draft to acquire his rights. Upon entering 2016 training camp, Francis switched to the defensive side of the ball after playing as a tight end during his college football career with the North Carolina A&T Aggies. He made his CFL debut on June 30, 2016 against the Toronto Argonauts, registering his first defensive tackle. Francis finished his rookie season leading the team in special team tackles, also being ranked 7 on the CFL rising sophomore list

After his graduation, Hussain subsequently joined the family business comprising large numbers of industries, textiles, agricultural farms, sugar and flour mills. He successfully contested in the non-partisan 1985 elections and was appointed as minister of industry in the government of Prime minister Muhammad Junejo, lasting until 1988.

Passage 2:In late July, a trough of low pressure, which Hurricane Blanche avoided, was situated over the northeastern Gulf of Mexico. The system developed into Tropical Depression Six at 12:00UTC on July28, while located about 60mi (100km) southwest of Cape San Blas, Florida. The depression combined with a building high pressure system, resulting in the development of a strong convergence zone. This, in turn, caused heavy rainfall along the Gulf Coast, particularly in southern Alabama and the Florida Panhandle. With sustained winds initially at 25mph (35km/h), the storm intensified slightly while tracking west-northwestward. Early on July29, the depression attained its peak intensity with maximum sustained winds of 35mph (55km/h) and a minimum barometric pressure of 1010mbar (29.83inHg). Several hours later, it made landfall in a rural area of St. Bernard Parish, Louisiana, with winds of 30mph (45km/h). The system curved northwestward and dissipated at 12:00UTC on July30, shortly after crossing into Mississippi. The remnants continued into northern Louisiana and then turned northward, before dissipating over Arkansas on August3.
Passage 3:The band released its debut album, Never Trust a Happy Song, on September 13, 2011 through Canvasback/Atlantic Records. They released 4 singles from the album Colours (which was featured on FIFA 12, albeit as the Captain Cuts remix), "Tongue Tied" (which went on to score the band a no. 1 on the US Alternative Chart and featured in several commercials (including one for Apple, and one for Coca-Cola) and an episode of Fox's Glee) Lovely Cup and Itchin On A Photograph. In support of their debut album, the band went on a headlining North American Fall tour and also performed with Two Door Cinema Club as their main support. In December, the band performed at KROQ Almost Acoustic Christmas, which takes place at the Gibson Amphitheatre, in Universal City. On January 3, 2012 the band kicked off their sold-out headline tour in Australia at the Factory Theatre in Sydney and continued their tour in Europe in February. The band began their US Spring 2012 tour on March 6 in Burlington, VT in support of Young The Giant. Throughout the sold-out headline tour the band had featured stops at Coachella Valley Music and Arts Festival, Sasquatch! Music Festival, and Bonnaroo Music and Arts Festival.

Question: What was the age of Lea Sirk the year that she placed twenty-second in the Eurovision Song Contest? Passage 1:Morton was a prolific photographer who took photographs of all aspects of life in North Carolina. His first published photograph came in 1935, when he was 14; a picture he took of a golfing scene was published as a North Carolina travel advertisement in Time Magazine. During his time at the University of North Carolina, he was a photographer for the student newspaper, the Daily Tar Heel. During World War II, Morton joined as a member of the Signal Corps, where he was assigned the job of newsreel photographer. He was sent to New Caledonia, an island off the coast of Australia, where he was attached to the 37th Infantry Division. Near the end of the war, Morton was assigned to take pictures of General Douglas MacArthur when MacArthur's regular photographer was sick. While on the island of Luzon in the Philippines, Morton was injured by a Japanese explosive and was awarded the Bronze Star and the Purple Heart.
Passage 2:A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. In 1931, the German engineer Bruno Lange developed a photo cell using silver selenide in place of copper oxide, although the prototype selenium cells converted less than 1% of incident light into electricity. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954. These early solar cells cost US$286/watt and reached efficiencies of 4.56%. In 1957, Mohamed M. Atalla developed the process of silicon surface passivation by thermal oxidation at Bell Labs. The surface passivation process has since been critical to solar cell efficiency.
Passage 3:Prior to the 2020 Contest, Slovenia had participated in the Eurovision Song Contest twenty-five times since its first entry in . Slovenia's highest placing in the contest, to this point, has been seventh place, which the nation achieved on two occasions: in 1995 with the song "Prisluhni mi" performed by Darja Svajger and in 2001 with the song "Energy" performed by Nusa Derenda. The country's only other top ten result was achieved in 1997 when Tanja Ribic performing "Zbudi se" placed tenth. Since the introduction of semi-finals to the format of the contest in 2004, Slovenia had thus far only managed to qualify to the final on six occasions. In 2018, Slovenia was represented by Lea Sirk and the song "Hvala, ne!", which qualified to the final and placed twenty-second. One year later, in 2019, Slovenia qualified for the final again with Zala Kralj & Gasper Santl, finishing in fifteenth place with the song "Sebi".
