Question: Question: Who was the last leader of the the country that was established after the year-long siege in 831? Passage:At the time of his accession, Theophilos was obliged to wage wars against the Arabs on two fronts. Sicily was once again invaded by the Arabs, who took Palermo after a year-long siege in 831, established the Emirate of Sicily, and gradually continued to expand across the island. The defence after the invasion of Anatolia by the Abbasid Caliph Al-Ma'mun in 830 was led by the Emperor himself, but the Byzantines were defeated and lost several fortresses. In 831 Theophilos retaliated by leading a large army into Cilicia and capturing Tarsus. The Emperor returned to Constantinople in triumph, but in the autumn he was defeated in Cappadocia. Another defeat in the same province in 833 forced Theophilos to sue for peace (Theophilos offered 100,000 gold dinars and the return of 7,000 prisoners), which he obtained the next year, after the death of Al-Ma'mun.

Question: Question: Did TJ Maxx make a profit the year Famous-Barr was re-branded as Macy's? Passage:Northpark Mall opened in 1972, on Range Line Road on the east side of Joplin. At the time, the mall was anchored by Montgomery Ward to the north, JCPenney to the south, and local chain Newman's the middle. Other stores included Walgreens, McCrory's, Ramsay's department store, For All Bible (which is still in business), Wyatts cafeteria, as well as many other stores. Newman's became Heer's in 1987, the same year that a new wing was built, and the mall received its first renovation. The new wing extended easterly from the JCPenney store. This new wing included two new anchors, Famous-Barr and Venture. The renovation also brought a food court as well as a new 5 screen cinema. In 1994, Heer's closed, and Famous-Barr moved its men's wear and home goods to the former Heer's space. That same year Sears built a store adjacent to Montgomery Ward, moving from an older store near downtown Joplin. In 1998 the mall received a minor renovation, changing only the color scheme. After the closure of the Venture chain in 1998, its anchor at the mall was converted to Shopko, but it closed in the early 2000s following the closure of Montgomery Ward in 2001. Both Famous-Barr locations were re-branded as Macy's in 2006. Montgomery Ward remained vacant until mid-2007, when its space was split between TJ Maxx and Steve & Barry's, the latter of which closed in 2008 and was replaced by Vintage Stock. In 2006 the mall received its first major renovation in nearly 20 years, changing the color scheme, adding all new lighting and floor tiles, and renovating the food court to a route 66 theme.

Question: Question: How many years after the Beach Boys released "Don't Worry Baby" did Roger Christian pass away? Passage:During a vocal tracking session in which Manson was singing over music already written for "Push It", the band felt that one of the lines in "Push It" would benefit from having a vocal chorus answering the words back to her. Inspired by Manson's spontaneous ad-lib of the phrase "don't worry baby" over the music, guitarist Steve Marker sampled the Beach Boys song "Don't Worry Baby" and used it as a backing vocal. The sample didn't work with what the band had already recorded so Manson re-sang the lines to fit the key and tempo of the song. Aware of the potential for incurring copyright legalities, the band debated whether or not to keep the line. Garbage and Brian Wilson coincidentally shared the same publishing company (Irving Music), and figuring that they had nothing to lose, contacted him through their company representative, sent him a copy of "Push It", and asked him for permission to use the interpolation. Wilson gave his blessing, and reportedly kept the tape. Both Wilson and Roger Christian, the deceased co-writer of "Don't Worry Baby", received a writing credit. A simpler interpolation credit was given to Herbie Azor, as the band's lawyers felt that there was a possible similarity of the line "Push it!" to his own "Push It", which had been a hit single for New York hip hop trio Salt-N-Pepa.
