Problem: The internal working language of the ECB is generally English, and press conferences are usually held in English. External communications are handled flexibly: English is preferred (though not exclusively) for communication within the ESCB (i.e. with other central banks) and with financial markets; communication with other national bodies and with EU citizens is normally in their respective language, but the ECB website is predominantly English; official documents such as the Annual Report are in the official languages of the EU.
When in communication with other nationalities, what language is generally used?
The answer is the following: normally in their respective language

Problem: If the data to be compressed is analog (such as a voltage that varies with time), quantization is employed to digitize it into numbers (normally integers). This is referred to as analog-to-digital (A/D) conversion. If the integers generated by quantization are 8 bits each, then the entire range of the analog signal is divided into 256 intervals and all the signal values within an interval are quantized to the same number. If 16-bit integers are generated, then the range of the analog signal is divided into 65,536 intervals.
What does "A/D" stand for?
The answer is the following: analog-to-digital

Problem: The international borders of the RSFSR touched Poland on the west; Norway and Finland on the northwest; and to its southeast were the Democratic People's Republic of Korea, Mongolian People's Republic, and the People's Republic of China. Within the Soviet Union, the RSFSR bordered the Ukrainian, Belarusian, Estonian, Latvian and Lithuanian SSRs to its west and Azerbaijan, Georgian and Kazakh SSRs to the south.
Which countries did the RSFSR border on the southeast?
The answer is the following: Democratic People's Republic of Korea, Mongolian People's Republic, and the People's Republic of China

Problem: On 25 September, Seoul was recaptured by South Korean forces. American air raids caused heavy damage to the KPA, destroying most of its tanks and much of its artillery. North Korean troops in the south, instead of effectively withdrawing north, rapidly disintegrated, leaving Pyongyang vulnerable. During the general retreat only 25,000 to 30,000 soldiers managed to rejoin the Northern KPA lines. On 27 September, Stalin convened an emergency session of the Politburo, in which he condemned the incompetence of the KPA command and held Soviet military advisers responsible for the defeat.
Who reclaimed the Seoul?
The answer is the following:
South Korean forces.
