Context and question: The mandolin has been used extensively in the traditional music of England and Scotland for generations. Simon Mayor is a prominent British player who has produced six solo albums, instructional books and DVDs, as well as recordings with his mandolin quartet the Mandolinquents. The instrument has also found its way into British rock music. The mandolin was played by Mike Oldfield (and introduced by Vivian Stanshall) on Oldfield's album Tubular Bells, as well as on a number of his subsequent albums (particularly prominently on Hergest Ridge (1974) and Ommadawn (1975)). It was used extensively by the British folk-rock band Lindisfarne, who featured two members on the instrument, Ray Jackson and Simon Cowe, and whose "Fog on the Tyne" was the biggest selling UK album of 1971-1972. The instrument was also used extensively in the UK folk revival of the 1960s and 1970s with bands such as Fairport Convention and Steeleye Span taking it on as the lead instrument in many of their songs. Maggie May by Rod Stewart, which hit No. 1 on both the British charts and the Billboard Hot 100, also featured Jackson's playing. It has also been used by other British rock musicians. Led Zeppelin's bassist John Paul Jones is an accomplished mandolin player and has recorded numerous songs on mandolin including Going to California and That's the Way; the mandolin part on The Battle of Evermore is played by Jimmy Page, who composed the song. Other Led Zeppelin songs featuring mandolin are Hey Hey What Can I Do, and Black Country Woman. Pete Townshend of The Who played mandolin on the track Mike Post Theme, along with many other tracks on Endless Wire. McGuinness Flint, for whom Graham Lyle played the mandolin on their most successful single, When I'm Dead And Gone, is another example. Lyle was also briefly a member of Ronnie Lane's Slim Chance, and played mandolin on their hit How Come. One of the more prominent early mandolin players in popular music was Robin Williamson in The Incredible String Band. Ian Anderson of Jethro Tull is a highly accomplished mandolin player (beautiful track Pussy Willow), as is his guitarist Martin Barre. The popular song Please Please Please Let Me Get What I Want by The Smiths featured a mandolin solo played by Johnny Marr. More recently, the Glasgow-based band Sons and Daughters featured the mandolin, played by Ailidh Lennon, on tracks such as Fight, Start to End, and Medicine. British folk-punk icons the Levellers also regularly use the mandolin in their songs. Current bands are also beginning to use the Mandolin and its unique sound - such as South London's Indigo Moss who use it throughout their recordings and live gigs. The mandolin has also featured in the playing of Matthew Bellamy in the rock band Muse. It also forms the basis of Paul McCartney's 2007 hit "Dance Tonight." That was not the first time a Beatle played a mandolin, however; that distinction goes to George Harrison on Gone Troppo, the title cut from the 1982 album of the same name. The mandolin is taught in Lanarkshire by the Lanarkshire Guitar and Mandolin Association to over 100 people. Also more recently hard rock supergroup Them Crooked Vultures have been playing a song based primarily using a mandolin. This song was left off their debut album, and features former Led Zeppelin bassist John Paul Jones.[citation needed]

Context and question: UCLA professor Richard H. Sander published an article in the November 2004 issue of the Stanford Law Review that questioned the effectiveness of racial preferences in law schools. He noted that, prior to his article, there had been no comprehensive study on the effects of affirmative action. The article presents a study that shows that half of all black law students rank near the bottom of their class after the first year of law school and that black law students are more likely to drop out of law school and to fail the bar exam. The article offers a tentative estimate that the production of new black lawyers in the United States would grow by eight percent if affirmative action programs at all law schools were ended. Less qualified black students would attend less prestigious schools where they would be more closely matched in abilities with their classmates and thus perform relatively better. Sander helped to develop a socioeconomically-based affirmative action plan for the UCLA School of Law after the passage of Proposition 209 in 1996, which prohibited the use of racial preferences by public universities in California. This change occurred after studies showed that the graduation rate of blacks at UCLA was 41%, compared to 73% for whites.
To which university does Richard H. Sander belong?
Answer: UCLA
Context and question: In central portions of the U.S., tornadoes are more common than anywhere else on Earth and touch down most commonly in the spring and summer. Deadly and destructive hurricanes occur almost every year along the Atlantic seaboard and the Gulf of Mexico. The Appalachian region and the Midwest experience the worst floods, though virtually no area in the U.S. is immune to flooding. The Southwest has the worst droughts; one is thought to have lasted over 500 years and to have hurt Ancestral Pueblo peoples. The West is affected by large wildfires each year.
Where are tornadoes most common on Earth?
Answer:
central portions of the U.S.
