Input: Question: Which of the entities that fought in the First Punic War was founded first? Passage 1:While still a youth in 265 BC, Fabius was consecrated an augur. It is unknown whether he participated in the First Punic War, fought between the Roman Republic and Carthage from 264 to 241 BC, or what his role might have been. Fabius' political career began in the years following that war. He was probably quaestor in 237 or 236 BC, and curule aedile about 235. During his first consulship, in 233 BC, Fabius was awarded a triumph for his victory over the Ligurians, whom he defeated and drove into the Alps. He was censor in 230, then consul a second time in 228. It is possible that he held the office of dictator for a first time around this time: according to Livy, Fabius's tenure of the dictatorship in 217 was his second term in that office, with Gaius Flaminius as his deputy and magister equitum during the first term: however Plutarch suggests that Flaminius was deputy instead to Marcus Minucius Rufus - presumably Fabius's great political rival of that name, who later served as deputy to Fabius himself (see below). It is of course possible that Flaminius was successively deputy to both, after Minucius's apparently premature deposition following bad augural omens: and also possible that little of note (other than, possibly, holding elections during the absence of consuls) was accomplished during either dictatorship.
Passage 2:During the Winter 2017 TCA Press Tour, series mainstays Sarah Paulson and Evan Peters were reported to be starring as the leads in the season. In March 2017, Billy on the Street host Billy Eichner was announced to be cast in the series, playing a role in the life of Paulson's character. His character is slated for appearing in "six or seven" episodes. The next month, it was reported that Scream Queens actress Billie Lourd will also star in the seventh installment of the series. In May 2017, Leslie Grossman, who starred in Murphy's series Popular, joined the cast of the series, and Angela Bassett hinted she may return in a recurring role. Despite this, Bassett didn't appear, but she did direct the episode "Drink the Kool-Aid". Later that month, it was confirmed via set pictures that Adina Porter and Cheyenne Jackson were also returning. In June 2017, Murphy confirmed via his Instagram account that Colton Haynes, whom Murphy worked with previously on second season of Scream Queens, was joining the casting for the seventh season. Later that month, set pictures revealed that Alison Pill was joining the cast of the season, seemingly portraying the partner of Sarah Paulson's character. In July 2017, Murphy revealed via his Twitter account that Lena Dunham was joining the season. She is set to play Valerie Solanas, author of the SCUM Manifesto and attempted murder of Andy Warhol, via flashbacks. Murphy also confirmed the returns of Frances Conroy and Mare Winningham. Conroy has appeared in all the seasons except Hotel, while Winningham has appeared in Coven, Freak Show, and Hotel. In August 2017, Murphy confirmed the return of Emma Roberts, who appeared in Coven and Freak Show, while Roanoke actors Chaz Bono and James Morosini also confirmed their returns. In the seventh episode, Murder House, Coven, and Freak Show actress Jamie Brewer returned to the show.
Passage 3:In ancient times the area around Changzhi (Including Jincheng) was known as Shangdang. Changzhi was the site of the Shangdang Campaign, the first battle between the Kuomintang and the People's Liberation Army after the end of World War II. The campaign began in August 1945 and lasted until October. It began when the local Shanxi warlord, Yan Xishan, attempted to retake the region from Communist forces. Yan's forces were eventually defeated by an army led by Liu Bocheng, who was later named one of China's Ten Great Marshals. Liu's political commissar was Deng Xiaoping, who later became China's "paramount leader". The campaign ended with the complete destruction of Yan's army, most of which joined the Communists after surrendering. Following the Shangdang Campaign, the Communists remained in control of the region until they won the civil war in 1949.
