The problem: Answer a question about this article:
The French were equipped with bronze, rifled muzzle-loading artillery, while the Prussians used new steel breech-loading guns, which had a far longer range and a faster rate of fire. Prussian gunners strove for a high rate of fire, which was discouraged in the French army in the belief that it wasted ammunition. In addition, the Prussian artillery batteries had 30% more guns than their French counterparts. The Prussian guns typically opened fire at a range of 2–3 kilometres (1.2–1.9 mi), beyond the range of French artillery or the Chassepot rifle. The Prussian batteries could thus destroy French artillery with impunity, before being moved forward to directly support infantry attacks.
What newer artillery were Prussians using?
****
The answer: steel breech-loading guns


The problem: Answer a question about this article:
Replicated CDs are mass-produced initially using a hydraulic press. Small granules of heated raw polycarbonate plastic are fed into the press. A screw forces the liquefied plastic into the mold cavity. The mold closes with a metal stamper in contact with the disc surface. The plastic is allowed to cool and harden. Once opened, the disc substrate is removed from the mold by a robotic arm, and a 15 mm diameter center hole (called a stacking ring) is created. The time it takes to "stamp" one CD is usually two to three seconds.
What size is the diameter of the center hole in a CD?
****
The answer: 15 mm

Critics labelled Gaddafi "despotic, cruel, arrogant, vain and stupid", with western governments and press presenting him as the "vicious dictator of an oppressed people". During the Reagan administration, the United States regarded him as "Public Enemy No. 1" and Reagan famously dubbed him the "mad dog of the Middle East". According to critics, the Libyan people lived in a climate of fear under Gaddafi's administration, due to his government's pervasive surveillance of civilians. Gaddafi's Libya was typically described by western commentators as "a police state". Opponents were critical of Libya's human rights abuses; according to Human Rights Watch (HRW) and others, hundreds of arrested political opponents often failed to receive a fair trial, and were sometimes subjected to torture or extrajudicial execution, most notably in the Abu Salim prison, including an alleged massacre on 29 June 1996 in which HRW estimated that 1,270 prisoners were massacred. Dissidents abroad or "stray dogs" were also publicly threatened with death and sometimes killed by government hit squads. His government's treatment of non-Arab Libyans has also came in for criticism from human rights activists, with native Berbers, Italians, Jews, refugees, and foreign workers all facing persecution in Gaddafist Libya. According to journalist Annick Cojean and psychologist Seham Sergewa, Gaddafi and senior officials raped and imprisoned hundreds or thousands of young women and reportedly raped several of his female bodyguards. Gaddafi's government was frequently criticized for not being democratic, with Freedom House consistently giving Libya under Gaddafi the "Not Free" ranking for civil liberties and political rights.
What did Reagan call Gaddafi?
****
The answer: mad dog of the Middle East
