[EX Q]: Question: How old was the British Admiral when he took control of the Southeast Asia Command? Passage 1:Silvanus was born in Gaul, the son of Bonitus, a Laetic Frankish general who had supported Constantine I in the civil war against Licinius. Like so many other Franks of his times, and like his father before him, he was a loyal and thoroughly romanized "barbarian" in the military service of the Empire. By AD 351, he held the rank of tribune and was one of the senior officers who defected to Emperor Constantius II at the Battle of Mursa Major, after initially supporting the usurper Magnentius. An able soldier, Silvanus was eventually promoted to the rank of Magister militum per Gallias, a crucial post, then in AD 352-353, Constantius personally entrusted him with the difficult task of driving the Alamanni tribesmen raiding and looting in Gaul back beyond the Rhine, and restoring the fast eroding Roman authority in the province. This Silvanus fulfilled partly by bribing the Alamanni chieftains with the taxes he had collected, partly by defeating the Alamanni in battle and partly by suppressing the local bagaudae insurrections flaring up again in central and northern Gaul.
 Passage 2:At the Potsdam Conference in July 1945, the Combined Chiefs of Staff decided that Indochina south of latitude 16° north was to be included in the Southeast Asia Command under British Admiral Mountbatten. Japanese forces located south of that line surrendered to him and those to the north surrendered to Generalissimo Chiang Kai-shek. In September 1945, Chinese forces entered Tonkin, and a small British task force landed at Saigon. The Chinese accepted the Vietnamese government under Hồ Chí Minh, then in power in Hanoi. The British refused to do likewise in Saigon, and deferred to the French there from the outset, against the ostensible support of the Việt Minh authorities by American OSS representatives. On V-J Day, September 2, Hồ Chí Minh had proclaimed in Hanoi the establishment of the Democratic Republic of Vietnam (DRV). The DRV ruled as the only civil government in all of Vietnam for a period of about 20 days, after the abdication of Emperor Bảo Đại, who had governed under Japanese rule. On 23 September 1945, with the knowledge of the British commander in Saigon, French forces overthrew the local DRV government, and declared French authority restored in Cochinchina. Guerrilla warfare began around Saigon immediately, but the French gradually retook control of the South and North of Indochina. Hồ Chí Minh agreed to negotiate the future status of Vietnam, but the talks, held in France, failed to produce a solution. After over one year of latent conflict, all-out war broke out in December 1946 between French and Việt Minh forces as Hồ Chí Minh and his government went underground. The French tried to stabilize Indochina by reorganizing it as a Federation of Associated States. In 1949, they put former Emperor Bảo Đại back in power, as the ruler of a newly established State of Vietnam.
 Passage 3:Like the star Epsilon Draconis in the constellation of Draco, Beta Cephei is visible primarily in the northern hemisphere, given its extreme northern declination of 70 degrees and 34 minutes. It is nevertheless visible to most observers throughout the world reaching as far south as cities like Harare in Zimbabwe, Santa Cruz de la Sierra in Bolivia or other settlements north ± 19° South latitude. It is circumpolar throughout all of Europe, northern Asia, and North American cities as far south as Guadalajara in west central Mexico. All other locations around the globe having a latitude greater than ± 20° North will notice that the star is always visible in the night sky. Because Beta Cephei is a faint third magnitude star, it may be difficult to identify in most light polluted cities, though in rural locations the star should be easily observable.

He is also an Honorary Fellow of the Royal Society of Literature.
 Passage 2:In 2008, Everett started by performing with one of her idols, Tina Turner, at the 2008 50th Annual Grammy Awards with Beyoncé. She featured in the video for "Love in This Club" by Usher and began a working relationship with him. In October of the same year, the video for "Single Ladies (Put a Ring on It)" was released, which featured a J-Setting choreography and contained only Beyoncé, Everett and dancer Ebony Williams. It has since gone viral, amassing over 580 million views and has been recreated thousands of times. It also won the MTV Video Music Award for Video of the Year. Everett featured in videos for both "Ego" and "Sweet Dreams" from I Am... Sasha Fierce (2008), and begun her second worldwide tour with Beyoncé, on the I Am... World Tour (2009–10). Here, Everett performed as the female Dance Captain for the entire tour. In 2010, Everett begun a working relationship with Ne-Yo and featured in three of his music videos from his album Libra Scale (2010); "One in a Million", "Champagne Life" and "Beautiful Monster".

[EX Q]: Question: How old was Bill Anderson the year that he helped co-write a song that became Wills's first No. 1 country hit? Passage 1:At the same time, other explanations were proposed that did not concord with general relativity. Edward Milne proposed an explanation compatible with special relativity but not general relativity that there was a giant explosion that could explain redshifts (see Milne universe). Others proposed that systematic effects could explain the redshift-distance correlation. Along this line, Fritz Zwicky proposed a "tired light" mechanism in 1929. Zwicky suggested that photons might slowly lose energy as they travel vast distances through a static universe by interaction with matter or other photons, or by some novel physical mechanism. Since a decrease in energy corresponds to an increase in light's wavelength, this effect would produce a redshift in spectral lines that increase proportionally with the distance of the source. The term "tired light" was coined by Richard Tolman in the early 1930s as a way to refer to this idea.
 Passage 2:Wish You Were Here was Wills's second album. This was his most commercially successful, earning a platinum certification from the Recording Industry Association of America. The lead-off single "I Do (Cherish You)" and its followup, "Don't Laugh at Me", both reached No. 2 on the country charts, with the former bringing him to the Billboard Hot 100 for the first time. Following the pair of No. 2-peaking songs was the album's title track. Co-written by Bill Anderson, Skip Ewing, and Debbie Moore, it became Wills's first No. 1 country hit in 1999. Later that year, the boy band 98 Degrees covered "I Do (Cherish You)" on their album 98 Degrees and Rising. Following "Wish You Were Here" was "She's in Love", the final single from Wish You Were Here, which peaked at No. 7. In 1998, Wills received an Academy of Country Music award for Top New Male Vocalist.
 Passage 3:In 1843, Barnett was elected (by the Georgia State Senate) to the position of Georgia Secretary of State, a position he held for three terms until 1849. He was subsequently elected to another, single, term in 1851. He was again elected to the position for the period 1861-1868, but was removed by the Military Governor at the onset of the Reconstruction era. It is said that Barnett twice saved the Great Seal of the State of Georgia. The first time was when Union troops under William Tecumseh Sherman were about to capture the State Capitol at Milledgeville. Barnett took the seal, and numerous official documents and Acts, and with the assistance of his wife Mary, buried them at his farm. After Sherman's troops marched on, Barnett returned the seal and the documents to the state. In 1866 Barnett again removed the Great Seal from the capitol. General Ruger, who was at that time acting as the Military Governor of Georgia, requested that Barnett affix the seal to an executive act, which Colonel Barnett could not approve. He refused to sanction the papers with the imprint of the seal and as a consequence was removed by General Ruger. Colonel Barnett then took the seal with him to prevent it from falling into the hands of what was considered an illegitimate Carpetbagger government which occupied the state: so that it was never affixed to any of the documents of misrule which followed under the carpetbag government. Since the seal was required, to certify official acts of the state government, the Reconstruction government fabricated a replacement. That replacement was identical in all respects except one. The soldier depicted on the replacement seal held his sword in the wrong hand. The period of the Reconstruction government in Georgia is thus referred to as the "Period of the False Seal". The Great Seal and documents were buried on Barnett's farm, and remained hidden there until 1868, when a new state constitution was enacted and a new government installed. After democrats regained control of state government, Barnett was again elected Secretary of State in 1873. Upon his return to office, both houses of the Legislature voted to present him with a replica of the Executive Seal, which replica is now in Savannah, Georgia, the property of the Georgia Historical Society. Barnett continued to serve as Secretary of State until his death on 2 February 1890. Toward the end of his more than 30 years of service as secretary of state under numerous administrations and into his late 80s, he was said to wear a row of three pairs of glasses. A portrait of Barnett hangs in the office of the Georgia Secretary of State to this day.
