[Q]: Question: Which producer who worked on Daylight Crossing is the oldest? Passage:Charley and Hattie collaborated with Jeff Trott (Sheryl Crow, Aimee Mann), Mike Elizondo (Dr. Dre, Fiona Apple), and Steve Booker (Duffy) on material that would become their album Daylight Crossing. Two years later they returned to the UK, where they worked with Universal Records sister company Mercury Records for the album's release. Daylight Crossing was produced by Steve Lipson and Youth, recorded at Sarm Hook End, Abbey Road and Olympic Studios. The album featured musicians Simon Tong and Simon Jones from the band The Verve and Steve Gadd and Pino Palladino. Daylight Crossing was released in June 2006 and became the 'Record of the Week' and 'Album of the Week' at BBC Radio 2, reaching No. 2 on UK's TV music video airplay chart. iTunes chose Daylight Crossing as 'Album of the Week' and singled out the song "Torches" as its 'Single of the Week' during its release week. The Webb Sisters performed on The Sharon Osbourne Show and toured in support of Jamie Cullum (for whom their brother Brad has played drums), Jason Mraz, James Morrison and Kubb, alongside band Leya and Joe Echo. Their song "Still The Only One" was played on the TV show Cane on CBS.

[Q]: Question: What age was Zapolya's son when Vrancic and Isabella Jagiellon moved to Transylvania? Passage:In 1530 John Zápolya appointed him as the provost of the Buda cathedral and as a royal secretary. Between 1530-1539 he was also the deputy of the King and after his death he remained with his widow, Isabella Jagiellon. In 1541 he moved with her to Transylvania, but he mostly traveled fulfilling diplomatic services because of his disagreement with cardinal Juraj Utješinović's policy of claiming the Hungarian throne for Isabella's and Zápolya's infant son (instead of conceding it to Ferdinand I as per Treaty of Nagyvárad). Utješinović, appointed by Zápolya as a guardian of his son, John Sigismund Zápolya, fought against Ferdinand and allied himself with the Ottoman Empire.

[Q]: Question: What is the current population of the county that New Mexico State Road 4 is the main highway through? Passage:The fire originated as a controlled burn that was part of the 10-year Bandelier National Monument plan for reducing fire hazard within the monument. The starting point was high on Cerro Grande, a 10,200-foot (3110-m) summit on the rim of the Valles Caldera not far north of New Mexico State Road 4, the main highway through Los Alamos County. Like many mountains in the Jemez, Cerro Grande was mainly covered with coniferous forest, composed largely of Ponderosa pine, Douglas fir, white fir, and aspen trees, with a characteristic rincon (meadow) on its southern slopes near the summit. This grassy area also represented the headwaters of Frijoles Creek (Rito de los Frijoles), which flows southeast into Frijoles Canyon and on to the Rio Grande, passing en route the main tourist areas at Bandelier. The plan for the burn (see the NPS summary below) called for initial ignition ("phase 1") to be in the rincon, followed by flanking fires ("phase 2") along the slightly higher country east and west of Frijoles Creek. Ignition of the phase-1 burn was scheduled for May 4, 2000.
