[EX Q]: Question: Who was older the year Dane appeared on Jackie Gleason's show, Otis Spann or Willie Dixon? Passage:By 1959, Louis Armstrong had asked Time magazine readers: "Did you get that chick? She's a gasser!" and invited her to appear with him on national television. She appeared with Armstrong on the Timex All-Star Jazz Show hosted by Jackie Gleason on January 7, 1959. She toured the East Coast with Jack Teagarden, appeared in Chicago with Art Hodes, Roosevelt Sykes, Little Brother Montgomery, Memphis Slim, Otis Spann, Willie Dixon and others, played New York with Wilbur De Paris and his band, and appeared on The Tonight Show Starring Johnny Carson as a solo guest artist. Other national TV work included The Steve Allen Show, Bobby Troup's Stars of Jazz, and Alfred Hitchcock Presents. In 1961, the singer opened her own club, Sugar Hill: Home of the Blues, on San Francisco's Broadway in the North Beach district, with the idea of creating a venue for the blues in a tourist district where a wider audience could hear it. There Dane performed regularly with her two most constant musical companions: Kenny "Good News" Whitson on piano and cornet and Wellman Braud, former Ellington bassist.

[EX Q]: Question: What is the age difference between the author of the novel Witnesses and the person who adapted it for the screen? Passage:After the political changes in 2000, Croatian cinema proved it could work in a completely free environment for the first time. As a result, at the beginning of this decade Croatian cinema flourishes again, and many critics write about "third golden era" (after the 1950s and 1960s). One of the most popular authors in the contemporary Croatian cinema is Vinko Bresan whose comedies Kako je poceo rat na mom otoku (How the War Started on My Island, 1997), and Marsal (Marshal Tito's Spirit, 1999) mix grotesque humor and political provocation. Bresan's war drama Svjedoci (Witnesses, based on a novel by Jurica Pavicic) was the first feature film from countries of former Yugoslavia which discussed the war crimes committed by "our guys", not the enemy. Film was screened in competition at the Berlin Film Festival in 2003. A Wonderful Night in Split (Ta divna splitska noc, 2004) by Arsen A. Ostojic received a nomination for the European Discovery EFA award, and Tu (Here, 2003) by Zrinko Ogresta was awarded at the Karlovy Vary Film Festival. Among other distinguished contemporary directors, internationally most recognized is Ognjen Svilicic, whose two films premiered at the Berlin Film Festival - Oprosti za kung fu (Sorry about Kung Fu, 2004) and Armin (2006). Armin was also Croatia's submission for the 2008 Academy Award, and although it didn't earn a nomination in the Best Foreign Language Film category, it did nevertheless receive the prestigious Best Foreign Film of 2007 Award given by the International Federation of Film Critics.

[EX Q]: Question: Which states aided the Latin Empire under the benner "Crusader States"? Passage:The NicaeanLatin wars were a series of wars between the Latin Empire and the Empire of Nicaea, starting with the dissolution of the Byzantine Empire by the Fourth Crusade in 1204. The Latin Empire was aided by other Crusader states established on Byzantine territory after the Fourth Crusade, as well as the Republic of Venice, while the Empire of Nicaea was assisted occasionally by the Second Bulgarian Empire, and sought the aid of Venice's rival, the Republic of Genoa. The conflict also involved the Greek state of Epirus, which also claimed the Byzantine inheritance and opposed Nicaean hegemony. The Nicaean reconquest of Constantinople in 1261 AD and the restoration of the Byzantine Empire under the Palaiologos dynasty did not end the conflict, as the Byzantines launched on and off efforts to reconquer southern Greece (the Principality of Achaea and the Duchy of Athens) and the Aegean islands until the 15th century, while the Latin powers, led by the Angevin Kingdom of Naples, tried to restore the Latin Empire and launched attacks on the Byzantine Empire.
