Please answer this: A friend asked me to answer this question: What is the full name of the vocalist who SR replaced with Lill-Babs?, using the article: Most of Melodifestivalen's rules are dictated by those of the Eurovision Song Contest.  However, regulations have been introduced by the Swedish broadcasters. The competition's official rules are released by SVT early in preparation for each year's Melodifestival, to ensure any changes are noted by songwriters and performers. There was a limit of six people on stage for each performance. This included the Melodifestivalen choir (huskören, literally "the house choir"), a five-person group of flexible backing singers used by most participants. Artists could use some or all of the back-up singers, or use their own group. All vocals had to be completely live; human voices were not allowed on backing tracks. However, from 2009, the number of performers allowed on stage was eight, and voices were allowed on backing tracks. A live orchestra was used every year from the event's debut to 2000, except 1985 and 1986. Two orchestras were used between 1960 and 1963, a large orchestra and Göte Wilhelmsons kvartett, a jazz quartet. Since 2001, participants have performed to backing tracks. Entries cannot be publicly broadcast until the semi-finals are previewed on radio. Entries eliminated in the semi-finals may be broadcast as soon as the semi-final has finished. An embargo is placed on songs that qualify for the later rounds until the previews for the Second Chance are broadcast. After this, restrictions on the broadcast of contestant songs are lifted.Broadcasters sometimes make sweeping changes to winning songs before they go to Eurovision. For example, at Melodifestivalen 1961, Siw Malmkvist won with "April, April". Performing after her victory, she stumbled on the lyrics of the song and laughed out loud. The press criticised this as childish. SR replaced her with Lill-Babs for the Eurovision Song Contest. The 1987 winner "Fyra bugg och en Coca Cola", performed by Lotta Engberg, is another example; the song's title was changed to "Boogaloo" for Eurovision, as use of a brand name was against the Contest's rules. This..., what would be the answer ?

Answer: Siw Malmkvist

Problem: A friend asked me to answer this question: What system pairs the eight songs off against each other?, using the article: Prior to the introduction of the current format of semifinals (deltävlingar) in 2002, the competition was usually a single live show. Under the current system, four semifinals are broadcast at 20:00 CET on consecutive Saturday nights. The semi-finals begin in early February, and seven songs compete in each show. Unlike in the final, no juries are used; televoting decides the results. The songs are performed live with telephone lines open for the first round of voting; two songs with the fewest votes do not qualify to the second round. The top five battle for a place in the final and Andra chansen round – the 1st and 2nd placed songs qualifying to the final, and the 3rd and 4th placed songs progressing to Andra chansen. Both finalists reprise their entries at the end of the broadcast. The organisation of a semi-final system for Melodifestivalen popularised televised heats at national Eurovision selections. A similar system was adopted by the Eurovision itself in 2004. The Second Chance round (Andra chansen) is the fifth heat in which the remaining four entries to the final are chosen. The third- and fourth-placed songs from each semi-final (eight songs in total) compete in the event. The first Second Chance round in 2002 had a panel of former winners decide the two finalists. Between 2003 and 2006, the semi-final performances were re-broadcast, and a round of voting narrowed the songs to three or four. Another round then determined the two finalists. The programme was broadcast on the Sunday afternoon after the fourth semi-final. It was held in a smaller venue than those that would have hosted the semi-finals—such as Berns Salonger in Stockholm, which hosted the Second Chance round in 2005. In 2007, the Second Chance round became a full semi-final, taking place in a venue comparable in size to those hosting the others. The expanded Second Chance takes place on a Saturday night, adding an extra week to the event's timetable. The format of voting also changed with the introduction of a knock-out system. The..., what would be the answer ?

A: a knock-out system

Q: A friend asked me to answer this question: Who does the drifter have a sweetly burgeoning relationship with?, using the article: Zac is a lonely, highly strung city trader on the edge of a psychological breakdown. He has lost everything—his job, his girlfriend Eva (Sophia Di Martino from "Flowers") and, most devastatingly, his weird and wayward younger sister Alice, the only family he had left. Alice is now a missing person, having disappeared on a narrow boat trip along with her kindred drifter and boyfriend Toby. Zac becomes increasingly frustrated with the futile attempts of the police to find them and, eventually, decides to take matters into his own inexpert hands by starting a terribly executed video blog and scouring the dark canals of the UK in a desperate, perhaps even deluded search for clues. Struggling for information and fast losing hope, Zac reflects on his past and the difficult relationship he had with Alice. Wracked with guilt and regret, his sanity starts to unravel as he fights with memories of her in the weeks leading up to her disappearance. As he remembers her sweetly burgeoning relationship with the mysterious Toby, however, he begins to wonder if there may in fact be a grander, wilder, much stranger explanation for their disappearance., what would be the answer ?
A:
Alice
