Question: Which county that I-24 goes through has the highest population? Passage:I-24 continues southeast through the rapidly growing suburbs of Nashville, and crosses into Rutherford County near the city of LaVergne, where there are three exits. Beginning at this point, I-24 is relatively straight and flat for most of its distance through Middle Tennessee. The straightest stretch of highway in Tennessee is located on I-24 between Lavergne and eastern Murfreesboro, where the route is perfectly straight for about fifteen miles, although the median widens and narrows. Four miles later is an interchange with SR 102, which connects to Smyrna and the Nissan Motor Manufacturing Plant. Another four miles later is an interchange with Interstate 840, the outer southern beltway around Nashville, and I-24 enters Murfreesboro, the largest suburb of Nashville. In Murfreesboro, I-24 has interchanges with SR 96 (which connects of Franklin), SR 99 (New Salem Highway), and US 231 (which connects to Lebanon and Shelbyville), respectively, and at the final Murfreesboro exit (US 231), the HOV lane designation ends, and I-24 narrows to six lanes and then four lanes a short distance later. Three miles later is an interchange with the Joe B. Jackson Parkway, which serves as an outer beltway around southeast Murfreesboro. I-24 then enters a more rural area, and at exit 97 has an interchange with SR 64, which connects to Shelbyville. I-24 then curves to the south, then the east, briefly enters Bedford County, and then Coffee County. At exit 105 is an interchange with US 41, and five miles later I-24 enters Manchester, where it has interchanges with SR 53, SR 55, and US 41, respectively. I-24 continues through a rural, largely agricultural area where it crosses into Grundy County and has an interchange with US 64 and SR 50.

Question: Was Kassel the capital of a country at the time? Passage:After his school-leaving examination (Abitur) at the secondary school Antonianum in Vechta Ludger Gerdes studied at the Academy of Arts in Münster with Timm Ulrichs and Lothar Baumgarten from 1975 to 1977, and from 1977 to 1982 at the Düsseldorf Academy of Arts with Gerhard Richter. At the beginning of the 1980s Gerdes stood out in exhibitions and actions with his criticism of the link between modern art, the museum and the temporary exhibition. At this time he exhibited among others along with Thomas Schütte. He pleaded for works of art as a means for the organization of public space and as a medium of communication. The English landscape garden was a particularly important historical model of this to him. At this time he was regarded as the intellectual head of the artist-group of Düsseldorf pattern makers (Düsseldorfer Modellbauer). In 1982 he was included in the documenta 7 in Kassel. He became known to a larger public in 1987 with his land art project A Ship for Münster (Ein Schiff für Münster) for the show "Skulptur.Projekte" in Münster. From 1990 to 1992 he taught at the Städelschule, Frankfurt; from 1998 to 2004 he was professor for painting and multimedia at the art academy in Karlsruhe; since 2005 he was professor for painting at the Muthesius Art Academy in Kiel. Parallel to his professorship he lived and worked as an artist in Munich and Düsseldorf.

Question: Which The Cars member who worked on This Side of Paradise album is the youngest? Passage:This Side of Paradise is the second solo studio album released by Ric Ocasek, lead singer and songwriter of The Cars. It was released in 1986 by Geffen Records. Though it was a solo album, other members of The Cars played significant roles. Greg Hawkes plays keyboards and bass throughout the album (he appears on most of Ocasek's solo albums), and also co-wrote "Hello Darkness" (most Cars albums feature one Ocasek/Hawkes tune). Benjamin Orr is on backing vocals for three songs. Along with Hawkes and Orr, the track "True To You" also features Elliot Easton on guitar. Had drummer David Robinson been present, the song would have been an unofficial Cars reunion. Both production and drumming were by Chris Hughes (formerly known as "Merrick", drummer for Adam and the Ants). Hughes was the recent producer of Tears for Fears most popular two albums. Steve Stevens from Billy Idol's band plays guitar on over half of the album.
