Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Peaks in France, Italy and Switzerland lie in the "Houillière zone", which consists of basement with sediments from the Mesozoic Era. High "massifs" with external sedimentary cover are more common in the Western Alps and were affected by Neogene Period thin-skinned thrusting whereas the Eastern Alps have comparatively few high peaked massifs. Similarly the peaks in Switzerland extending to western Austria (Helvetic nappes) consist of thin-skinned sedimentary folding that detached from former basement rock.
When compared to the Western Alps, what area has few high peaked massifs?

Question: By the late 80s, House had moved West, particularly to San Francisco, Oakland, Los Angeles, Fresno, San Diego and Seattle. Los Angeles saw a huge explosion of underground raves and DJs, notably DJs Marques Wyatt and Billy Long, who spun at Jewel's Catch One, the oldest dance club in America. In 1989, the L.A. based, former EBN-OZN singer/rapper Robert Ozn started indie house label One Voice Records, releasing the Mike "Hitman" Wilson remix of Dada Nada's "Haunted House," which garnered instant club and mix show radio play in Chicago, Detroit and New York as well as in the U.K. and France. The record shot up to Number Five on the Billboard Club Chart, marking it as the first House record by a white artist to chart in the U.S. Dada Nada, the moniker for Ozn's solo act, released in 1990, what has become a classic example of jazz-based Deep House, the Frankie Knuckles and David Morales remix of Dada Nada's "Deep Love" (One Voice Records/US, Polydor/UK), featuring Ozn's lush, crooning vocals and muted trumpet improvisational solos, underscoring Deep House's progression into a genre that integrated jazz and pop songwriting structures – a feature which continued to set it apart from Acid House and Techno.
