Problem: Punjab, Pakistan:

For the popular taste however, light music, particularly Ghazals and folk songs, which have an appeal of their own, the names of Mehdi Hassan, Ghulam Ali, Nur Jehan, Malika Pukhraj, Farida Khanum, Roshen Ara Begum, and Nusrat Fateh Ali Khan are well-known. Folk songs and dances of the Punjab reflect a wide range of moods: the rains, sowing and harvesting seasons. Luddi, Bhangra and Sammi depict the joy of living. Love legends of Heer Ranjha, Mirza Sahiban, Sohni Mahenwal and Saiful Mulk are sung in different styles.

Problem: An exception is the United States, where patents filed prior to 8 June 1995 expire 17 years after the publication date of the patent, but application extensions make it possible for a patent to issue much later than normally expected (see submarine patents). The various MP3-related patents expire on dates ranging from 2007 to 2017 in the U.S. Patents filed for anything disclosed in ISO CD 11172 a year or more after its publication are questionable. If only the known MP3 patents filed by December 1992 are considered, then MP3 decoding has been patent-free in the US since 22 September 2015 when U.S. Patent 5,812,672 expired which had a PCT filing in October 1992. If the longest-running patent mentioned in the aforementioned references is taken as a measure, then the MP3 technology will be patent-free in the United States on 30 December 2017 when U.S. Patent 5,703,999, held by the Fraunhofer-Gesellschaft and administered by Technicolor, expires.
What year is the latest that MP3 related patents will expire on in the United States?

Answer: 2017

Question: Waitz was influential among the British ethnologists. In 1863 the explorer Richard Francis Burton and the speech therapist James Hunt broke away from the Ethnological Society of London to form the Anthropological Society of London, which henceforward would follow the path of the new anthropology rather than just ethnology. It was the 2nd society dedicated to general anthropology in existence. Representatives from the French Societe were present, though not Broca. In his keynote address, printed in the first volume of its new publication, The Anthropological Review, Hunt stressed the work of Waitz, adopting his definitions as a standard.[n 5] Among the first associates were the young Edward Burnett Tylor, inventor of cultural anthropology, and his brother Alfred Tylor, a geologist. Previously Edward had referred to himself as an ethnologist; subsequently, an anthropologist.
Is there an answer to this question: What society did James Hunt form in the 18th century?

Answer: unanswerable

There are two levels of service provided a free service to civilians and licensed service to the Chinese government and military. The free civilian service has a 10-meter location-tracking accuracy, synchronizes clocks with an accuracy of 10 nanoseconds, and measures speeds to within 0.2 m/s. The restricted military service has a location accuracy of 10 centimetres, can be used for communication, and will supply information about the system status to the user. To date, the military service has been granted only to the People's Liberation Army and to the Military of Pakistan.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the range of accuracy for the licensed service used by Chinese government and military?
Ah, so..
10 centimetres
