In his 2003 paper, "Human Genetic Diversity: Lewontin's Fallacy", A. W. F. Edwards argued that rather than using a locus-by-locus analysis of variation to derive taxonomy, it is possible to construct a human classification system based on characteristic genetic patterns, or clusters inferred from multilocus genetic data. Geographically based human studies since have shown that such genetic clusters can be derived from analyzing of a large number of loci which can assort individuals sampled into groups analogous to traditional continental racial groups. Joanna Mountain and Neil Risch cautioned that while genetic clusters may one day be shown to correspond to phenotypic variations between groups, such assumptions were premature as the relationship between genes and complex traits remains poorly understood. However, Risch denied such limitations render the analysis useless: "Perhaps just using someone's actual birth year is not a very good way of measuring age. Does that mean we should throw it out? ... Any category you come up with is going to be imperfect, but that doesn't preclude you from using it or the fact that it has utility."

Risch thinks imperfect categories still have what?
Answer: utility

Problem: During the Mexican Revolution, Alvaro Obregon invited a group of Canadian German-speaking Mennonites to resettle in Mexico. By the late 1920s, some 7,000 had immigrated to Chihuahua State and Durango State, almost all from Canada, only a few from the U.S. and Russia. Today, Mexico accounts for about 42% of all Mennonites in Latin America. Mennonites in the country stand out because of their light skin, hair, and eyes. They are a largely insular community that speaks a form of German and wear traditional clothing. They own their own businesses in various communities in Chihuahua, and account for about half of the state's farm economy, excelling in cheese production.
Today, Mexico accounts for what percentage of Mennonites in Latin America?
The answer is the following: 42%

As a doctoral student at Germany's University of Erlangen-Nuremberg, Karlheinz Brandenburg began working on digital music compression in the early 1980s, focusing on how people perceive music. He completed his doctoral work in 1989. MP3 is directly descended from OCF and PXFM, representing the outcome of the collaboration of Brandenburgworking as a postdoc at AT&T-Bell Labs with James D. Johnston ("JJ") of AT&T-Bell Labswith the Fraunhofer Institut for Integrated Circuits, Erlangen, with relatively minor contributions from the MP2 branch of psychoacoustic sub-band coders. In 1990, Brandenburg became an assistant professor at Erlangen-Nuremberg. While there, he continued to work on music compression with scientists at the Fraunhofer Society (in 1993 he joined the staff of the Fraunhofer Institute).
Where did Bradenburg become an assistant professor at?
Erlangen-Nuremberg

Input: Ottoman Empire
Ottoman Divan poetry was a highly ritualized and symbolic art form. From the Persian poetry that largely inspired it, it inherited a wealth of symbols whose meanings and interrelationshipsboth of similitude ( mura'at-i nazir / tenasub) and opposition ( tezad) were more or less prescribed. Divan poetry was composed through the constant juxtaposition of many such images within a strict metrical framework, thus allowing numerous potential meanings to emerge. The vast majority of Divan poetry was lyric in nature: either gazels (which make up the greatest part of the repertoire of the tradition), or kasides. There were, however, other common genres, most particularly the mesnevi, a kind of verse romance and thus a variety of narrative poetry; the two most notable examples of this form are the Leyli and Majnun of Fuzuli and the Husn u Ask of Seyh Galib.

What kind of poetry inspired Ottoman Divan Poetry?
Output: Persian poetry

Input: Article: According to Tony Sclafani from MSNBC, "It's worth noting that before Madonna, most music mega-stars were guy rockers; after her, almost all would be female singers ... When The Beatles hit America, they changed the paradigm of performer from solo act to band. Madonna changed it backwith an emphasis on the female." Howard Kramer, curatorial director of the Rock and Roll Hall of Fame and Museum, asserted that "Madonna and the career she carved out for herself made possible virtually every other female pop singer to follow ... She certainly raised the standards of all of them ... She redefined what the parameters were for female performers." According to Fouz-Hernandez, subsequent female singers such as Britney Spears, Christina Aguilera, Kylie Minogue, the Spice Girls, Destiny's Child, Jennifer Lopez, and Pink were like her "daughters in the very direct sense that they grew up listening to and admiring Madonna, and decided they wanted to be like her." Time magazine included her in the list of the "25 Most Powerful Women of the Past Century", where she became one of only two singers to be included, alongside Aretha Franklin. She also topped VH1's lists of "100 Greatest Women in Music" and "50 Greatest Women of the Video Era".

Now answer this question: Who changed the dynamics of the singers back to mostly female?

Output: Madonna

Problem: The Order is limited to 300 Knights and Dames Grand Cross, 845 Knights and Dames Commander, and 8,960 Commanders. There are no limits applied to the total number of members of the fourth and fifth classes, but no more than 858 Officers and 1,464 Members may be appointed per year. Foreign recipients, as honorary members, do not contribute to the numbers restricted to the Order as full members do. Although the Order of the British Empire has by far the highest number of members of the British Orders of Chivalry, with over 100,000 living members worldwide, there are fewer appointments to knighthoods than in other orders.
How many Knights and Dames Commander?
The answer is the following:
845
