Article: With the extension of Turkish dominion into the Balkans, the strategic conquest of Constantinople became a crucial objective. The empire had managed to control nearly all former Byzantine lands surrounding the city, but in 1402 the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Sultan Bayezid I as a prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power, bringing an end to the Interregnum, also known as the Fetret Devri.

Question: Timur was the founder of what?
Ans: Timurid Empire

Article: In 1860, Adolf Bastian (18261905) argued for "the psychic unity of mankind". He proposed that a scientific comparison of all human societies would reveal that distinct worldviews consisted of the same basic elements. According to Bastian, all human societies share a set of "elementary ideas" (Elementargedanken); different cultures, or different "folk ideas" (Volkergedanken), are local modifications of the elementary ideas. This view paved the way for the modern understanding of culture. Franz Boas (18581942) was trained in this tradition, and he brought it with him when he left Germany for the United States.

Question: Who trained under Bastian's ideas on culture?
Ans: Franz Boas

Article: The term Hokkien (; hkkn) is itself a term not used in Chinese to refer to the dialect, as it simply means Fujian province. In Chinese linguistics, these dialects are known by their classification under the Quanzhang Division (Chinese: ; pinyin: Quanzhang pian) of Min Nan, which comes from the first characters of the two main Hokkien urban centers Quanzhou and Zhangzhou. The variety is also known by other terms such as the more general Min Nan (traditional Chinese: , ; simplified Chinese: , ; pinyin: Minnanyu, Minnanhua; Peh-oe-ji: Ban-lam-gi,Ban-lam-oe) or Southern Min, and Fulaohua (traditional Chinese: ; simplified Chinese: ; pinyin: Fulaohua; Peh-oe-ji: Ho-lo-oe). The term Hokkien (Chinese: ; Peh-oe-ji: hok-kian oe;Tai-lo:Hok-kian-ue), on the other hand, is used commonly in South East Asia to refer to Min-nan dialects.

Question: Where is the term Hokkien mainly used?
Ans: South East Asia

Article: LaserDiscs potentially had a much longer lifespan than videocassettes. Because the discs were read optically instead of magnetically, no physical contact needs to be made between the player and the disc, except for the player's clamp that holds the disc at its center as it is spun and read. As a result, playback would not wear the information-bearing part of the discs, and properly manufactured LDs would theoretically last beyond one's lifetime. By contrast, a VHS tape held all of its picture and sound information on the tape in a magnetic coating which is in contact with the spinning heads on the head drum, causing progressive wear with each use (though later in VHS's lifespan, engineering improvements allowed tapes to be made and played back without contact). Also, the tape was thin and delicate, and it was easy for a player mechanism, especially on a low quality or malfunctioning model, to mishandle the tape and damage it by creasing it, frilling (stretching) its edges, or even breaking it.

Question: Where do VHS tapes store their information?
Ans:
magnetic coating
