Article: Gymnasts sprint down a runway, which is a maximum of 25 meters in length, before hurdling onto a spring board. The gymnast is allowed to choose where they start on the runway. The body position is maintained while "punching" (blocking using only a shoulder movement) the vaulting platform. The gymnast then rotates to a standing position. In advanced gymnastics, multiple twists and somersaults may be added before landing. Successful vaults depend on the speed of the run, the length of the hurdle, the power the gymnast generates from the legs and shoulder girdle, the kinesthetic awareness in the air, and the speed of rotation in the case of more difficult and complex vaults.

Question: What is the maximum length of the runway gymnasts sprint down before hurdling onto a spring board?
Ans: 25 meters

Article: Simultaneous videoconferencing among three or more remote points is possible by means of a Multipoint Control Unit (MCU). This is a bridge that interconnects calls from several sources (in a similar way to the audio conference call). All parties call the MCU, or the MCU can also call the parties which are going to participate, in sequence. There are MCU bridges for IP and ISDN-based videoconferencing. There are MCUs which are pure software, and others which are a combination of hardware and software. An MCU is characterised according to the number of simultaneous calls it can handle, its ability to conduct transposing of data rates and protocols, and features such as Continuous Presence, in which multiple parties can be seen on-screen at once. MCUs can be stand-alone hardware devices, or they can be embedded into dedicated videoconferencing units.

Question: What enables videoconferencing to connect three or more remote points?
Ans: Multipoint Control Unit (MCU)


Article: In 1756 Austria was making military preparations for war with Prussia and pursuing an alliance with Russia for this purpose. On June 2, 1746, Austria and Russia concluded a defensive alliance that covered their own territory and Poland against attack by Prussia or the Ottoman Empire. They also agreed to a secret clause that promised the restoration of Silesia and the countship of Glatz (now Kłodzko, Poland) to Austria in the event of hostilities with Prussia. Their real desire, however, was to destroy Frederick’s power altogether, reducing his sway to his electorate of Brandenburg and giving East Prussia to Poland, an exchange that would be accompanied by the cession of the Polish Duchy of Courland to Russia. Aleksey Petrovich, Graf (count) Bestuzhev-Ryumin, grand chancellor of Russia under Empress Elizabeth, was hostile to both France and Prussia, but he could not persuade Austrian statesman Wenzel Anton von Kaunitz to commit to offensive designs against Prussia so long as Prussia was able to rely on French support.

Question: What Russian-Austrian agreement preceded the Seven Years War that started in 1755-56?
Ans:
June 2, 1746, Austria and Russia concluded a defensive alliance that covered their own territory and Poland against attack by Prussia or the Ottoman Empire
