Example Input: Passage: In 2004, a large share of natural gas reserves in Iran were untapped. The addition of new hydroelectric stations and the streamlining of conventional coal and oil-fired stations increased installed capacity to 33,000 megawatts. Of that amount, about 75% was based on natural gas, 18% on oil, and 7% on hydroelectric power. In 2004, Iran opened its first wind-powered and geothermal plants, and the first solar thermal plant is to come online in 2009. Iran is the third country in the world to have developed GTL technology. Question: How much of Iran's 33k megawatt installed capacity was based on oil? 
Example Output: 18%

Example Input: Passage: Due to historically close ties with France, French literature came to constitute the major Western influence on Ottoman literature throughout the latter half of the 19th century. As a result, many of the same movements prevalent in France during this period also had their Ottoman equivalents: in the developing Ottoman prose tradition, for instance, the influence of Romanticism can be seen during the Tanzimat period, and that of the Realist and Naturalist movements in subsequent periods; in the poetic tradition, on the other hand, it was the influence of the Symbolist and Parnassian movements that became paramount. Question: The poetic tradition had its biggest influence on what Ottoman literary movements?
Example Output: the Symbolist and Parnassian movements

Example Input: Passage: Most elevators have a location in which the permit for the building owner to operate the elevator is displayed. While some jurisdictions require the permit to be displayed in the elevator cab, other jurisdictions allow for the operating permit to be kept on file elsewhere – such as the maintenance office – and to be made available for inspection on demand. In such cases instead of the permit being displayed in the elevator cab, often a notice is posted in its place informing riders of where the actual permits are kept. Question: What type of notice can be displayed in the elevator in lieu of the permit?
Example Output:
a notice is posted in its place informing riders of where the actual permits are kept.
