Question: How many weeks did the single that peaked at number nine spend on the charts? Passage:"Go Girl" was the first single released from the album. It was originally the lead single from the album, but the single achieved minimum success and was later deemed a promo single. However, the single managed to reach the top of the charts in Japan. The album's official lead single, "Never Ever", which features Young Jeezy, was released in the United States in January 2009 and reached a peak of number nine on the U.S. Hot R&B/Hip-Hop Songs. The second single, "Love Sex Magic", featuring Justin Timberlake, became a worldwide hit, peaking within the top ten in twenty countries including the U.S., where it peaked at number ten on the Billboard Hot 100. It went on to be certified platinum in Australia and received a gold accreditation in New Zealand. It received a nomination for "Best Pop Collaboration with Vocals" at the 52nd Annual Grammy Awards and also for Best Choreography in a Video at the 2009 MTV Video Music Awards. "Like A Surgeon" was the fourth single from the album. The song received no promotion and no single cover nor music video was released. However, the song did manage to peak at number fifty-nine on the Hot R&B/Hip-Hop Songs chart from airplay alone. "Work", the final single, achieved moderate success in international markets.

Question: Does the scene on the west side of the piazza take place in Italy? Passage:In Morning, a lady makes her way to church, shielding herself with her fan from the shocking view of two men pawing at the market girls. The scene is the west side of the piazza at Covent Garden, indicated by a part of the Palladian portico of Inigo Jones's Church of St Paul visible behind Tom King's Coffee House, a notorious venue celebrated in pamphlets of the time. Henry Fielding mentions the coffee house in both The Covent Garden Tragedy and Pasquin. At the time Hogarth produced this picture, the coffee house was being run by Tom's widow, Moll King, but its reputation had not diminished. Moll opened the doors once those of the taverns had shut, allowing the revellers to continue enjoying themselves from midnight until dawn. The mansion with columned portico visible in the centre of the picture, No. 43 King Street, is attributed to architect Thomas Archer (later 1st Baron Archer) and occupied by him at the date of Hogarth's works. It was situated on the north side of the piazza, while the coffee house was on the south side, as depicted in Hogarth's original painting. In the picture, it is early morning and some revellers are ending their evening: a fight has broken out in the coffee house and, in the melée, a wig flies out of the door. Meanwhile, stallholders set out their fruit and vegetables for the day's market. Two children who should be making their way to school have stopped, entranced by the activity of the market, in a direct reference to Swift's A Description of the Morning in which children "lag with satchels in their hands". Above the clock is Father Time and below it the inscription Sic transit gloria mundi. The smoke rising from the chimney of the coffee house connects these portents to the scene below.
