Example Input: 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.

He then was a basketball announcer for his alma mater, the University of Kansas, for one year, then went on to call games for the NFL's Kansas City Chiefs from 198593 after several years hosting and producing surrounding pre-game and post-game programming (coincidentally, current Packers play-by-play voice Wayne Larrivee left the Chiefs position open when he began a thirteen-year run as the voice of the Chicago Bears). Harlan also split time with the University of Missouri (198689) calling football and basketball games, and worked as the play-by-play voice of the NBA's Minnesota Timberwolves for nine seasons (198998). On the network level, Harlan called NFL football for NBC in 1991, college football for ESPN in 199293, NFL for Fox from 199497, and joined Turner Sports in 1996 to cover NBA playoff games (he would begin calling games throughout the entire season in 1997, which he continues to do to this day). He began working for CBS in 1998.
