Question: Efforts by local kings to fight the invaders led to the formation of new political entities. In Anglo-Saxon England, King Alfred the Great (r. 871899) came to an agreement with the Viking invaders in the late 9th century, resulting in Danish settlements in Northumbria, Mercia, and parts of East Anglia. By the middle of the 10th century, Alfred's successors had conquered Northumbria, and restored English control over most of the southern part of Great Britain. In northern Britain, Kenneth MacAlpin (d. c. 860) united the Picts and the Scots into the Kingdom of Alba. In the early 10th century, the Ottonian dynasty had established itself in Germany, and was engaged in driving back the Magyars. Its efforts culminated in the coronation in 962 of Otto I (r. 936973) as Holy Roman Emperor. In 972, he secured recognition of his title by the Byzantine Empire, which he sealed with the marriage of his son Otto II (r. 967983) to Theophanu (d. 991), daughter of an earlier Byzantine Emperor Romanos II (r. 959963). By the late 10th century Italy had been drawn into the Ottonian sphere after a period of instability; Otto III (r. 9961002) spent much of his later reign in the kingdom. The western Frankish kingdom was more fragmented, and although kings remained nominally in charge, much of the political power devolved to the local lords.

Answer: the Kingdom of Alba
Question: FETs are further divided into depletion-mode and enhancement-mode types, depending on whether the channel is turned on or off with zero gate-to-source voltage. For enhancement mode, the channel is off at zero bias, and a gate potential can "enhance" the conduction. For the depletion mode, the channel is on at zero bias, and a gate potential (of the opposite polarity) can "deplete" the channel, reducing conduction. For either mode, a more positive gate voltage corresponds to a higher current for n-channel devices and a lower current for p-channel devices. Nearly all JFETs are depletion-mode because the diode junctions would forward bias and conduct if they were enhancement-mode devices; most IGFETs are enhancement-mode types.
Try to answer this question if possible: At what point is a channel on in depletion-mode?
Answer: at zero bias
Question: Windows 8 development started before Windows 7 had shipped in 2009. At the Consumer Electronics Show in January 2011, it was announced that the next version of Windows would add support for ARM system-on-chips alongside the existing x86 processors produced by vendors, especially AMD and Intel. Windows division president Steven Sinofsky demonstrated an early build of the port on prototype devices, while Microsoft CEO Steve Ballmer announced the company's goal for Windows to be "everywhere on every kind of device without compromise." Details also began to surface about a new application framework for Windows 8 codenamed "Jupiter", which would be used to make "immersive" applications using XAML (similarly to Windows Phone and Silverlight) that could be distributed via a new packaging system and a rumored application store.

Question: Tourism is also an important industry in Miami. Along with finance and business, the beaches, conventions, festivals and events draw over 38 million visitors annually into the city, from across the country and around the world, spending $17.1 billion. The Art Deco District in South Beach, is reputed as one of the most glamorous in the world for its nightclubs, beaches, historical buildings, and shopping. Annual events such as the Sony Ericsson Open, Art Basel, Winter Music Conference, South Beach Wine & Food Festival, and Mercedes-Benz Fashion Week Miami attract millions to the metropolis every year.
Try to answer this question if possible: How many tourists don't come to Miami each year?
Answer:
