Problem: A physical USB device may consist of several logical sub-devices that are referred to as device functions. A single device may provide several functions, for example, a webcam (video device function) with a built-in microphone (audio device function). This kind of device is called a composite device. An alternative to this is compound device, in which the host assigns each logical device a distinctive address and all logical devices connect to a built-in hub that connects to the physical USB cable.
A single device can provide an audio device function such as?
The answer is the following: built-in microphone

Problem: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
Instead of an electromagnetic wave, what did the light quantum behave as in some regards?
The answer is the following: an electrically neutral particle

Problem: By law, religious communities must register by the State Committee on Religious Affairs (SCRA) and with local authorities. Registration with the SCRA requires a charter, a list of 10 or more members, and evidence of local government approval prayer site location. Religious groups who do not have a physical structure are not allowed to gather publicly for prayer. Failure to register can result in large fines and closure of place of worship. There are reports that registration on the local level is sometimes difficult to obtain. People under the age of 18 are also barred from public religious practice.
What do religions communities have to register with?
The answer is the following: State Committee on Religious Affairs (SCRA) and with local authorities

Problem: In 1260, control passed to the Mamluk sultans of Egypt. The country was located between the two centres of Mamluk power, Cairo and Damascus, and only saw some development along the postal road connecting the two cities. Jerusalem, although left without the protection of any city walls since 1219, also saw a flurry of new construction projects centred around the Al-Aqsa Mosque compound (the Temple Mount). In 1266 the Mamluk Sultan Baybars converted the Cave of the Patriarchs in Hebron into an exclusive Islamic sanctuary and banned Christians and Jews from entering, which previously would be able to enter it for a fee. The ban remained in place until Israel took control of the building in 1967.
When was control passed to the Mamluk sultans of Egypt?
The answer is the following:
1260
