Question: Of the 8 fraternities at the University of Alabama in the 1800s, which was the oldest on a national level? Passage:Greek letter organizations (GLOs) first appeared at the university in 1847 when two men visiting from Yale University installed a chapter of Delta Kappa Epsilon. When DKE members began holding secret meetings in the old state capitol building that year, the administration strongly voiced its disapproval. Over a few more decades, 7 other fraternities appeared at UA: Alpha Delta Phi in 1850, Phi Gamma Delta in 1855, Sigma Alpha Epsilon in 1856 (this was the founding chapter), Kappa Sigma in 1867, Sigma Nu in 1874, Sigma Chi in 1876, and Phi Delta Theta in 1877. Anti-fraternity laws were imposed that year, but were lifted in the 1890s. Women at the university founded the Zeta chapter of Kappa Delta sorority in 1903. Alpha Delta Pi soon followed.

Question: What year was Minaj's tour where she typically wore four major different outfits? Passage:Throughout the tour, Minaj has incorporated multiple outfits into the show that correlate with the major themes of The Pinkprint. The show usually consists of four major outfits, each of which stylistically represent different segments of the show. For the first section of the show, Minaj is dressed in black lingerie covered with a black polka dot mesh catsuit, and is supported by an all female group of dancers who are also dressed in solid black mesh catsuits. The second section of the show sees Minaj performing in a gold-dipped skirt with matching thigh-high boots, and a gold bra, while her dancers, now both male and female, are dressed in gold attire as well. The designers of the second segment outfit were later revealed to be The Blonds, who created the costume especially for Minaj to perform in while on tour. The third and fourth portions of the show have seen multiple changes in wardrobe throughout the extent of the tour. For the third segment, Minaj has either worn a frilly black dress or a solid pink dress depending on the date of the show. And for the fourth and final segment for the tour, Minaj's ensemble either consists of a jumpsuit that can be described as looking like "a broken pink disco ball" on the front with an all mesh back, or a frilly pink bra with a shiny tutu and pink lace tights. Marissa G. Muller from MTV described the latter of the two outfits as "50% Barbie, 50% Ballerina", while also adding that Minaj looked like "the prettiest ballerina Barbie of them all" alongside her female dancers who were almost identically dressed. Muller also noted that the outfit was reminiscent of Minaj's look around the time she released her debut album, Pink Friday (2010). Overall, Nadeska Alexis, also from MTV, greatly praised Minaj's wardrobe choice for the tour stating that the outfits were "sexy", "elegant", and "sweet".

Question: How long had Arista Records existed at the time of signing Uropa Lula? Passage:In 1980, Lloyd formed Uropa Lula with Hilde Swendgaard (manager) and Kevin Smith (drums), making two short films, "Here in the Sun" and "At Night Time" with Video Active. They were joined by Colin Prior (bass) and Peter Fromm (keyboards) in 1981 and began performing live in London, opening for John Cale, Alternative TV and Depeche Mode. American bass player Allan Dias replaced Prior in August of the same year. In September, the band recorded three songs, "Here's a Medal", "Timber Fall" I and "My Black Hour" for the Nicky Horne Capital Radio show. Leeds-born drummer Andrew Edge joined the group later that year. Uropa Lula signed to Arista Records in May 1982 and spent the rest of that year recording album tracks and their first two singles, "Our Love Has Just Begun" and "Fell Upon a Jewel" at Trident Studios, The Manor Studio, Townhouse Studios and RAK Studios. To tie in with the release of the first single, the band recorded a live session for the David Jensen show on Radio 1 for the BBC. The session was produced by Dale Griffin, the English drummer and founding member of 1970s rock band Mott the Hoople and featured two songs, "Here's a Medal" and "Timber Fall I". A month later, Uropa Lula returned to London's Capital Radio to record their second live session for the Nicky Horne show playing two songs, "I Am My Older Brother" and "Leather and Metal (Winter's Here)". In the fall of 1982, guitarist Chester Kamen and keyboard player Carol Isaacs joined the group in time for tours of the UK and US in 1983. The group's opening US show was at the Ritz in New York (1 February 1982). This was followed by dates at the Mudd Club (7 February 1982), the in Washington, D.C., the New Jersey City Gardens and a show at the Brooklyn Zoo (26 February 1982) where they shared the bill with Holly and the Italians. Upon their return to the UK, on 2 June 1982 the group played at the Camden Palace (now called Koko) and opened for Big Country at the Royal Court Theatre, Liverpool (19 June 1982) and John Cale at The Venue, Victoria, London (5 July 1982). With some irony, the band had by this point changed their name to Viva Lula and as part of the promotion of their third single, "Dad Sings the Blues"; they toured the UK with Big Country in June 1983. Lloyd disbanded the group in October 1983 and embarked on a solo career, albeit continuing to work with Uropa Lula members Kamen, Dias and Smith throughout the '80s.
