Problem: Between the 5th and 8th centuries, new peoples and individuals filled the political void left by Roman centralised government. The Ostrogoths settled in Italy in the late 5th century under Theoderic (d. 526) and set up a kingdom marked by its co-operation between the Italians and the Ostrogoths, at least until the last years of Theodoric's reign. The Burgundians settled in Gaul, and after an earlier realm was destroyed by the Huns in 436 formed a new kingdom in the 440s. Between today's Geneva and Lyon, it grew to become the realm of Burgundy in the late 5th and early 6th centuries. In northern Gaul, the Franks and Britons set up small polities. The Frankish Kingdom was centred in north-eastern Gaul, and the first king of whom much is known is Childeric (d. 481).[G] Under Childeric's son Clovis (r. 509511), the Frankish kingdom expanded and converted to Christianity. Britons, related to the natives of Britannia modern-day Great Britain settled in what is now Brittany.[H] Other monarchies were established by the Visigoths in Iberia, the Suevi in north-western Iberia, and the Vandals in North Africa. In the 6th century, the Lombards settled in northern Italy, replacing the Ostrogothic kingdom with a grouping of duchies that occasionally selected a king to rule over them all. By the late 6th century this arrangement had been replaced by a permanent monarchy.
Who was the first notable king of the Franks?
The answer is the following: Childeric

Problem: One of the first demonstrations of the ability for telecommunications to help sign language users communicate with each other occurred when AT&T's videophone (trademarked as the "Picturephone") was introduced to the public at the 1964 New York World's Fair two deaf users were able to communicate freely with each other between the fair and another city. Various universities and other organizations, including British Telecom's Martlesham facility, have also conducted extensive research on signing via videotelephony. The use of sign language via videotelephony was hampered for many years due to the difficulty of its use over slow analogue copper phone lines, coupled with the high cost of better quality ISDN (data) phone lines. Those factors largely disappeared with the introduction of more efficient video codecs and the advent of lower cost high-speed ISDN data and IP (Internet) services in the 1990s.
What was the name of AT&T's videophone device?
The answer is the following: Picturephone

Problem: In September 2006, the iTunes Store began to offer additional games for purchase with the launch of iTunes 7, compatible with the fifth generation iPod with iPod software 1.2 or later. Those games were: Bejeweled, Cubis 2, Mahjong, Mini Golf, Pac-Man, Tetris, Texas Hold 'Em, Vortex, Asphalt 4: Elite Racing and Zuma. Additional games have since been added. These games work on the 6th and 5th generation iPod Classic and the 5th and 4th generation iPod Nano.
What was the first generation of iPod Classic on which games like Mahjong and Tetris could be played?
The answer is the following: 5th generation

Problem: Y-Gerat was the most complex system of the three. It was, in effect, an automatic beam-tracking system, operated through the bomber's autopilot. The single approach beam along which the bomber tracked was monitored by a ground controller. The signals from the station were retransmitted by the bomber's equipment. This way the distance the bomber travelled along the beam could be precisely verified. Direction-finding checks also enabled the controller to keep the crew on an exact course. The crew would be ordered to drop their bombs either by issue of a code word by the ground controller, or at the conclusion of the signal transmissions which would stop. Although its maximum usable range was similar to the previous systems, it was not unknown for specific buildings to be hit.
What kind of checks help to keep the plane on course?
The answer is the following:
Direction-finding
