Problem: House music:

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.

Problem: Washington University in St. Louis:

The West Campus is located about one mile (1.6 km) to the west of the Danforth Campus in Clayton, Missouri, and primarily consists of a four-story former department store building housing mostly administrative space. The West Campus building was home to the Clayton branch of the Famous-Barr department store until 1990, when the University acquired the property and adjacent parking and began a series of renovations. Today, the basement level houses the West Campus Library, the University Archives, the Modern Graphic History Library, and conference space. The ground level still remains a retail space. The upper floors house consolidated capital gifts, portions of alumni and development, and information systems offices from across the Danforth and Medical School campuses. There is also a music rehearsal room on the second floor. The West Campus is also home to the Center for the Application of Information Technologies (CAIT), which provides IT training services.

Where is the West Campus of Washington University located?

A: Clayton, Missouri


Problem: Printed circuit board:

Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side. Once surface-mounting came into use, small-sized SMD components were used where possible, with through-hole mounting only of components unsuitably large for surface-mounting due to power requirements or mechanical limitations, or subject to mechanical stress which might damage the PCB.

Which type of construction is more expensive?
---
A: Through-hole


Problem: Alps:

High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the 3,500 m (11,483 ft) level. The 1,817 square kilometres (702 sq mi) of the Alps covered by glaciers in 1876 had shrunk to 1,342 km2 (518 sq mi) by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland.

How much of the glaciation in Austria disappeared?
---
A:
Forty percent
