I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "On July 16, 1989, the Popular Front of Azerbaijan held its first congress and elected Abulfaz Elchibey, who would become President, as its Chairman. On August 19, 600,000 protesters jammed Baku’s Lenin Square (now Azadliq Square) to demand the release of political prisoners. In the second half of 1989, weapons were handed out in Nagorno-Karabakh. When Karabakhis got hold of small arms to replace hunting rifles and crossbows, casualties began to mount; bridges were blown up, roads were blockaded, and hostages were taken."?
