Input: Read this: Several campus safety strategies have been pioneered at Yale. The first campus police force was founded at Yale in 1894, when the university contracted city police officers to exclusively cover the campus. Later hired by the university, the officers were originally brought in to quell unrest between students and city residents and curb destructive student behavior. In addition to the Yale Police Department, a variety of safety services are available including blue phones, a safety escort, and 24-hour shuttle service.
Question: Why was the campus police established?

Output: quell unrest between students and city residents


Input: Read this: To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.
Question: What positive effects does a slower-evaporating filament enable?

Output: more efficient light source


Input: Read this: Economic reform efforts continued with the support of international organizations, notably the World Bank and the International Monetary Fund. The reform program came to a halt in June 1997 when civil war erupted. When Sassou Nguesso returned to power at the end of the war in October 1997, he publicly expressed interest in moving forward on economic reforms and privatization and in renewing cooperation with international financial institutions. However, economic progress was badly hurt by slumping oil prices and the resumption of armed conflict in December 1998, which worsened the republic's budget deficit.
Question: Who did not express interest in economic reforms?

Output: unanswerable


Input: Read this: The Carnival in Uruguay covers more than 40 days, generally beginning towards the end of January and running through mid March. Celebrations in Montevideo are the largest. The festival is performed in the European parade style with elements from Bantu and Angolan Benguela cultures imported with slaves in colonial times. The main attractions of Uruguayan Carnival include two colorful parades called Desfile de Carnaval (Carnival Parade) and Desfile de Llamadas (Calls Parade, a candombe-summoning parade).
Question: What is summoned by the Desfile de Llamadas parade?

Output:
candombe
