From the late 19th century, the South used a colloquial term, the one-drop rule, to classify as black a person of any known African ancestry. This practice of hypodescent was not put into law until the early 20th century. Legally the definition varied from state to state. Racial definition was more flexible in the 18th and 19th centuries before the American Civil War. For instance, President Thomas Jefferson held persons who were legally white (less than 25% black) according to Virginia law at the time, but, because they were born to slave mothers, they were born into slavery, according to the principle of partus sequitur ventrem, which Virginia adopted into law in 1662.
When did Virginia adopt The Principle of Partus Sequitur Ventrem?
A: 1662

A new delimitation of the federal territory keeps being debated in Germany, though "Some scholars note that there are significant differences among the American states and regional governments in other federations without serious calls for territorial changes ...", as political scientist Arthur B. Gunlicks remarks. He summarizes the main arguments for boundary reform in Germany: "... the German system of dual federalism requires strong Länder that have the administrative and fiscal capacity to implement legislation and pay for it from own source revenues. Too many Länder also make coordination among them and with the federation more complicated ...". But several proposals have failed so far; territorial reform remains a controversial topic in German politics and public perception.
How many proposals have failed so far?
A: several

A more sophisticated MP3 encoder can produce variable bitrate audio. MPEG audio may use bitrate switching on a per-frame basis, but only layer III decoders must support it. VBR is used when the goal is to achieve a fixed level of quality. The final file size of a VBR encoding is less predictable than with constant bitrate. Average bitrate is VBR implemented as a compromise between the two: the bitrate is allowed to vary for more consistent quality, but is controlled to remain near an average value chosen by the user, for predictable file sizes. Although an MP3 decoder must support VBR to be standards compliant, historically some decoders have bugs with VBR decoding, particularly before VBR encoders became widespread.
Which type of decoder must support bitrate switching on a per-frame basis?
A: layer III

The trophy comes in three parts - the cup itself, plus a lid and a base. There have been two designs of trophy in use, but five physical trophies have been presented. The original trophy, known as the "little tin idol", was 18 inches high and made by Martin, Hall & Co. It was stolen in 1895 and never recovered, and so was replaced by an exact replica, used until 1910. The FA decided to change the design after the 1909 winners, Manchester United, made their own replica, leading the FA to realise they did not own the copyright. This new, larger design was by Messers Fattorini and Sons, and was used from 1911. In order to preserve this original, from 1992 it was replaced by an exact replica, although this had to be replaced after just over two decades, after showing wear and tear from being handled more than in previous eras. This third replica, first used in 2014, was built heavier to withstand the increased handling. Of the four surviving trophies, only the 1895 replica has entered private ownership.
How many parts does the trophy come in? 
A:
The trophy comes in three parts
