Problem: Cubism:

Cubism and modern European art was introduced into the United States at the now legendary 1913 Armory Show in New York City, which then traveled to Chicago and Boston. In the Armory show Pablo Picasso exhibited La Femme au pot de moutarde (1910), the sculpture Head of a Woman (Fernande) (1909–10), Les Arbres (1907) amongst other cubist works. Jacques Villon exhibited seven important and large drypoints, his brother Marcel Duchamp shocked the American public with his painting Nude Descending a Staircase, No. 2 (1912). Francis Picabia exhibited his abstractions La Danse à la source and La Procession, Seville (both of 1912). Albert Gleizes exhibited La Femme aux phlox (1910) and L'Homme au balcon (1912), two highly stylized and faceted cubist works. Georges Braque, Fernand Léger, Raymond Duchamp-Villon, Roger de La Fresnaye and Alexander Archipenko also contributed examples of their cubist works.

What 1910 piece did Albert Gleizes present in that show that introduced Cubism to the USA? 
---
A: La Femme aux phlox


Problem: In the U.S., the music was being developed to create a more sophisticated sound,[citation needed] moving beyond just drum loops and short samples. In Chicago, Marshall Jefferson had formed the house group Ten City Byron Burke, Byron Stingily & Herb Lawson(from "intensity"). New York–based performers such as Mateo & Matos and Blaze had slickly produced disco house tracks. In Detroit a proto-techno music sound began to emerge with the recordings of Juan Atkins, Derrick May and Kevin Saunderson.
what sound emerged in Detroit with the recordings of juan atkins and derrick may?
---
Answer: proto-techno music sound

Phosphor-based LED efficiency losses are due to the heat loss from the Stokes shift and also other phosphor-related degradation issues. Their luminous efficacies compared to normal LEDs depend on the spectral distribution of the resultant light output and the original wavelength of the LED itself. For example, the luminous efficacy of a typical YAG yellow phosphor based white LED ranges from 3 to 5 times the luminous efficacy of the original blue LED because of the human eye's greater sensitivity to yellow than to blue (as modeled in the luminosity function). Due to the simplicity of manufacturing the phosphor method is still the most popular method for making high-intensity white LEDs. The design and production of a light source or light fixture using a monochrome emitter with phosphor conversion is simpler and cheaper than a complex RGB system, and the majority of high-intensity white LEDs presently on the market are manufactured using phosphor light conversion.
What are some of the luminous efficacies of yellow phosphor based white LED compared to blue?
A: 3 to 5 times the luminous efficacy


Context and question: In 1991, there were only two proposals available that could be completely assessed for an MPEG audio standard: Musicam (Masking pattern adapted Universal Subband Integrated Coding And Multiplexing) and ASPEC (Adaptive Spectral Perceptual Entropy Coding). The Musicam technique, as proposed by Philips (the Netherlands), CCETT (France) and Institut für Rundfunktechnik (Germany) was chosen due to its simplicity and error robustness, as well as its low computational power associated with the encoding of high quality compressed audio. The Musicam format, based on sub-band coding, was the basis of the MPEG Audio compression format (sampling rates, structure of frames, headers, number of samples per frame).
Which other quality alongside simplicty was key in selecting this proposal?
Answer: error robustness


Question: The most obvious function of clothing is to improve the comfort of the wearer, by protecting the wearer from the elements. In hot climates, clothing provides protection from sunburn or wind damage, while in cold climates its thermal insulation properties are generally more important. Shelter usually reduces the functional need for clothing. For example, coats, hats, gloves, and other superficial layers are normally removed when entering a warm home, particularly if one is residing or sleeping there. Similarly, clothing has seasonal and regional aspects, so that thinner materials and fewer layers of clothing are generally worn in warmer seasons and regions than in colder ones.
Is there an answer to this question: The least obvious improvement bestowed by clothing is what?

Answer: unanswerable

Notre Dame alumni work in various fields. Alumni working in political fields include state governors, members of the United States Congress, and former United States Secretary of State Condoleezza Rice. A notable alumnus of the College of Science is Medicine Nobel Prize winner Eric F. Wieschaus. A number of university heads are alumni, including Notre Dame's current president, the Rev. John Jenkins. Additionally, many alumni are in the media, including talk show hosts Regis Philbin and Phil Donahue, and television and radio personalities such as Mike Golic and Hannah Storm. With the university having high profile sports teams itself, a number of alumni went on to become involved in athletics outside the university, including professional baseball, basketball, football, and ice hockey players, such as Joe Theismann, Joe Montana, Tim Brown, Ross Browner, Rocket Ismail, Ruth Riley, Jeff Samardzija, Jerome Bettis, Brett Lebda, Olympic gold medalist Mariel Zagunis, professional boxer Mike Lee, former football coaches such as Charlie Weis, Frank Leahy and Knute Rockne, and Basketball Hall of Famers Austin Carr and Adrian Dantley. Other notable alumni include prominent businessman Edward J. DeBartolo, Jr. and astronaut Jim Wetherbee.
Who is the current president of Notre Dame?
A:
Rev. John Jenkins
