Question: What team did the captain that left Stoke in 2007 go to? Passage:He joined fellow Championship side Stoke City for a 225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.

question:
Question: Which TLC hit that reached top 10 on the UK Singles Chart was the most successful commercially? Passage:The Very Best of TLC: Crazy Sexy Hits material is taken from four of their studio albums: Ooooooohhh... On the TLC Tip (1992), CrazySexyCool (1994), FanMail (1999), and 3D (2002), and Now & Forever: The Hits (2003), which were all recorded from 1991 to 2003. Their 1993 cover of The Time's "Get It Up" for the soundtrack to Poetic Justice does not appear on any of their studio albums, but still appears on the compilation along with the trio's most successful singles in the United Kingdom. These include "No Scrubs", which placed at number three on the UK Singles Chart and was awarded a platinum certification from the British Phonographic Industry (BPI); "Waterfalls", which peaked at number four on the UK Singles Chart and also achieved platinum status; "Unpretty", a silver-certificated single which peaked at number six on the UK Singles Chart, and "Creep", which also peaked at number six on the UK Singles Chart after being reissued across the UK and Europe. It did not, however, include "Dear Lie", a moderately received UK single which was certified silver. Instead, the non-charting songs "Come Get Some", "Damaged" and "Get It Up" were included in the final track listing, with "Whoop De Woo" (a non-album track) and "In Your Arms Tonight" (from 3D) the only two non-single tracks that appeared the compilation.
