Input: Read this: In 2007, the country with the highest estimated incidence rate of TB was Swaziland, with 1,200 cases per 100,000 people. India had the largest total incidence, with an estimated 2.0 million new cases. In developed countries, tuberculosis is less common and is found mainly in urban areas. Rates per 100,000 people in different areas of the world were: globally 178, Africa 332, the Americas 36, Eastern Mediterranean 173, Europe 63, Southeast Asia 278, and Western Pacific 139 in 2010. In Canada and Australia, tuberculosis is many times more common among the aboriginal peoples, especially in remote areas. In the United States Native Americans have a fivefold greater mortality from TB, and racial and ethnic minorities accounted for 84% of all reported TB cases.
Question: What was the rate of TB cases per 100,000 people in Swaziland in 2010?

Output: unanswerable

Input: Read this: Encompassing a wide variety of post-Romantic styles composed through the year 2000, 20th century classical music includes late romantic, modern, high-modern, and postmodern styles of composition. Modernism (18901930) marked an era when many composers rejected certain values of the common practice period, such as traditional tonality, melody, instrumentation, and structure. The high-modern era saw the emergence of neo-classical and serial music. A few authorities have claimed high-modernism as the beginning of postmodern music from about 1930. Others have more or less equated postmodern music with the "contemporary music" composed from the late 20th century through to the early 21st century.
Question: Postmodern music is also know as what?

Output: contemporary music

Input: Read this: Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, ('frost') is transliterated moroz, and ('mouse'), mysh or mys'. Once commonly used by the majority of those living outside Russia, transliteration is being used less frequently by Russian-speaking typists in favor of the extension of Unicode character encoding, which fully incorporates the Russian alphabet. Free programs leveraging this Unicode extension are available which allow users to type Russian characters, even on Western 'QWERTY' keyboards.
Question: What coding was created in Russia?

Output: unanswerable

Input: Read this: On tracks that London Underground share with National Rail third-rail stock (the Bakerloo and District lines both have such sections), the centre rail is connected to the running rails, allowing both types of train to operate, at a compromise voltage of 660 V. Underground trains pass from one section to the other at speed; lineside electrical connections and resistances separate the two types of supply. These routes were originally solely electrified on the four-rail system by the LNWR before National Rail trains were rewired to their standard three-rail system to simplify rolling stock use.
Question: What is the maximum voltage of the two UK rail systems?

Output:
unanswerable
