Question: When was the Empire that dominated the People of Totanac ethnicity formed? Passage:Totonacapan refers to the historical extension where the Totonac people of Mexico dominated, as well as to a region in the modern states of Veracruz and Puebla. The historical territory was much larger than the currently named region, extending from the Cazones River in the north to the Papaloapan River in the south and then west from the Gulf of Mexico into what is now the Sierra Norte de Puebla region and into parts of Hidalgo. When the Spanish arrived, the Totonac ethnicity dominated this large region, although they themselves were dominated by the Aztec Empire. For this reason, they allied with Hernán Cortés against Tenochtitlán. However, over the colonial period, the Totonac population and territory shrank, especially after 1750 when mestizos began infiltrating Totonacapan, taking political and economic power. This continued into the 19th and 20th centuries, prompting the division of most of historical Totonacpan between the states of Puebla and Veracruz. Today, the term refers only to a region in the north of Veracruz were Totonac culture is still important. This region is home to the El Tajín and Cempoala archeological sites as well as Papantla, which is noted for its performance of the Danza de los Voladores.

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 Brešan whose comedies Kako je počeo rat na mom otoku (How the War Started on My Island, 1997), and Maršal (Marshal Tito's Spirit, 1999) mix grotesque humor and political provocation. Brešan's war drama Svjedoci (Witnesses, based on a novel by Jurica Pavičić) 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 noć, 2004) by Arsen A. Ostojić 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 Sviličić, 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.
