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

Example Input: 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.
Example Output: 400

Example Input: Why did the NTC take over?, Context: Following his defeat in the civil war, Gaddafi's system of governance was dismantled and replaced under the interim government of the NTC, who legalised trade unions and freedom of the press. In July 2012, elections were held to form a new General National Congress (GNC), who officially took over governance from the NTC in August. The GNC proceeded to elect Mohammed Magariaf as president of the chamber, and then voted Mustafa A.G. Abushagur as Prime Minister; when Abushagar failed to gain congressional approval, the GNC instead elected Ali Zeidan to the position. In January 2013, the GNC officially renamed the Jamahiriyah as the "State of Libya".
Example Output: Following his defeat in the civil war, Gaddafi's system of governance was dismantled

Example Input: what work of writing is mentioned last?, Context: A generation later, the Irish Anglican bishop, George Berkeley (1685–1753), determined that Locke's view immediately opened a door that would lead to eventual atheism. In response to Locke, he put forth in his Treatise Concerning the Principles of Human Knowledge (1710) an important challenge to empiricism in which things only exist either as a result of their being perceived, or by virtue of the fact that they are an entity doing the perceiving. (For Berkeley, God fills in for humans by doing the perceiving whenever humans are not around to do it.) In his text Alciphron, Berkeley maintained that any order humans may see in nature is the language or handwriting of God. Berkeley's approach to empiricism would later come to be called subjective idealism.
Example Output:
Alciphron
