Input: Read this: Since the 2006 FIFA World Cup, the internal and external evaluation of Germany's national image has changed. In the annual Nation Brands Index global survey, Germany became significantly and repeatedly more highly ranked after the tournament. People in 20 different states assessed the country's reputation in terms of culture, politics, exports, its people and its attractiveness to tourists, immigrants and investments. Germany has been named the world's second most valued nation among 50 countries in 2010. Another global opinion poll, for the BBC, revealed that Germany is recognised for the most positive influence in the world in 2010. A majority of 59% have a positive view of the country, while 14% have a negative view.
Question: What year was the turning point for Germany in the Nation Brands Index?

Output: 2006

Input: Read this: In the United Kingdom, sociologists and other scholars influenced by Marxism, such as Stuart Hall (19322014) and Raymond Williams (19211988), developed cultural studies. Following nineteenth-century Romantics, they identified "culture" with consumption goods and leisure activities (such as art, music, film, food, sports, and clothing). Nevertheless, they saw patterns of consumption and leisure as determined by relations of production, which led them to focus on class relations and the organization of production.
Question: Which scientist created Marxism in the United Kingdom?

Output: unanswerable

Input: Read this: Railroads have been an important method of transportation in Montana since the 1880s. Historically, the state was traversed by the main lines of three east-west transcontinental routes: the Milwaukee Road, the Great Northern, and the Northern Pacific. Today, the BNSF Railway is the state's largest railroad, its main transcontinental route incorporating the former Great Northern main line across the state. Montana RailLink, a privately held Class II railroad, operates former Northern Pacific trackage in western Montana.
Question: What is the states largest railway?

Output: BNSF Railway

Input: Read this: DC commutating electric motors, if fitted with laminated pole pieces, become universal motors because they can also operate on AC; reversing the current in both stator and rotor does not reverse the motor. But the now-standard AC distribution frequencies of 50 and 60 Hz caused difficulties with inductive reactance and eddy current losses. Many railways chose low AC frequencies to overcome these problems. They must be converted from utility power by motor-generators or static inverters at the feeding substations or generated at dedicated traction powerstations.
Question: The now-standard DC frequencies are what?

Output:
unanswerable
