Problem: Please answer a question about the following article about High-definition television:
50 Hz systems support three scanning rates: 50i, 25p and 50p. 60 Hz systems support a much wider set of frame rates: 59.94i, 60i, 23.976p, 24p, 29.97p, 30p, 59.94p and 60p. In the days of standard definition television, the fractional rates were often rounded up to whole numbers, e.g. 23.976p was often called 24p, or 59.94i was often called 60i. 60 Hz high definition television supports both fractional and slightly different integer rates, therefore strict usage of notation is required to avoid ambiguity. Nevertheless, 29.97i/59.94i is almost universally called 60i, likewise 23.976p is called 24p.
What three scanning rates do 50 Hz systems support?
A: 50i, 25p and 50p
Problem: Please answer a question about the following article about Ottoman Empire:
During his brief majority reign, Murad IV (16121640) reasserted central authority and recaptured Iraq (1639) from the Safavids. The resulting Treaty of Zuhab of that same year decisively parted the Caucasus and adjacent regions between the two neighbouring empires as it had already been defined in the 1555 Peace of Amasya. The Sultanate of women (16481656) was a period in which the mothers of young sultans exercised power on behalf of their sons. The most prominent women of this period were Kosem Sultan and her daughter-in-law Turhan Hatice, whose political rivalry culminated in Kosem's murder in 1651. During the Koprulu Era (16561703), effective control of the Empire was exercised by a sequence of Grand Viziers from the Koprulu family. The Koprulu Vizierate saw renewed military success with authority restored in Transylvania, the conquest of Crete completed in 1669, and expansion into Polish southern Ukraine, with the strongholds of Khotyn and Kamianets-Podilskyi and the territory of Podolia ceding to Ottoman control in 1676.
When was Kosem murdered?
A: 1651
Problem: Please answer a question about the following article about Railway electrification system:
Railways must operate at variable speeds. Until the mid 1980s this was only practical with the brush-type DC motor, although such DC can be supplied from an AC catenary via on-board electric power conversion. Since such conversion was not well developed in the late 19th century and early 20th century, most early electrified railways used DC and many still do, particularly rapid transit (subways) and trams. Speed was controlled by connecting the traction motors in various series-parallel combinations, by varying the traction motors' fields, and by inserting and removing starting resistances to limit motor current.
What is speed limit for railways?
A: variable speeds
Problem: Please answer a question about the following article about Brigham Young University:
All students and faculty, regardless of religion, are required to agree to adhere to an honor code. Early forms of the Church Educational System Honor Code are found as far back as the days of the Brigham Young Academy and early school President Karl G. Maeser. Maeser created the "Domestic Organization", which was a group of teachers who would visit students at their homes to see that they were following the schools moral rules prohibiting obscenity, profanity, smoking, and alcohol consumption. The Honor Code itself was not created until about 1940, and was used mainly for cases of cheating and academic dishonesty. President Wilkinson expanded the Honor Code in 1957 to include other school standards. This led to what the Honor Code represents today: rules regarding chastity, dress, grooming, drugs, and alcohol. A signed commitment to live the honor code is part of the application process, and must be adhered by all students, faculty, and staff. Students and faculty found in violation of standards are either warned or called to meet with representatives of the Honor Council. In certain cases, students and faculty can be expelled from the school or lose tenure. Both LDS and non-LDS students are required to meet annually with a Church leader to receive an ecclesiastical endorsement for both acceptance and continuance. Various LGBT advocacy groups have protested the honor code and criticized it as being anti-gay, and The Princeton Review ranked BYU as the 3rd most LGBT-unfriendly school in the United States.
What was BYU's Honor Code mainly used for upon its creation?
A:
cases of cheating and academic dishonesty
