In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: What is the lowest ISO mentioned?, Context: Some high-speed black-and-white films, such as Ilford Delta 3200 and Kodak T-MAX P3200, are marketed with film speeds in excess of their true ISO speed as determined using the ISO testing method. For example, the Ilford product is actually an ISO 1000 film, according to its data sheet. The manufacturers do not indicate that the 3200 number is an ISO rating on their packaging. Kodak and Fuji also marketed E6 films designed for pushing (hence the "P" prefix), such as Ektachrome P800/1600 and Fujichrome P1600, both with a base speed of ISO 400.
[EX A]: 400

[EX Q]: what is the second time period mentioned?, Context: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
[EX A]: 1830

[EX Q]: Who was vain?, Context: 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.
