Problem: In 1469, following the Treaty of St. Omer, Upper Alsace was sold by Archduke Sigismund of Austria to Charles the Bold, Duke of Burgundy. Although Charles was the nominal landlord, taxes were paid to Frederick III, Holy Roman Emperor. The latter was able to use this tax and a dynastic marriage to his advantage to gain back full control of Upper Alsace (apart from the free towns, but including Belfort) in 1477 when it became part of the demesne of the Habsburg family, who were also rulers of the empire. The town of Mulhouse joined the Swiss Confederation in 1515, where it was to remain until 1798.
In what year was Upper Alsace sold to the Archduke Sigismund?
The answer is the following: 1469

Problem: The evolution of Proto-Greek should be considered within the context of an early Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages. The characteristically Greek representation of word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language, which also seems to share some other phonological and morphological peculiarities of Greek; this has led some linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.
What progression coincided with the the early Greek states that makes it difficult to give credit for the language and differences ?
The answer is the following: Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages.

Problem: By the early 2000s, LaserDisc was completely replaced by DVD in the North American retail marketplace, as neither players nor software were then produced. Players were still exported to North America from Japan until the end of 2001. The format has retained some popularity among American collectors, and to a greater degree in Japan, where the format was better supported and more prevalent during its life. In Europe, LaserDisc always remained an obscure format. It was chosen by the British Broadcasting Corporation (BBC) for the BBC Domesday Project in the mid-1980s, a school-based project to commemorate 900 years since the original Domesday Book in England. From 1991 up until the early 2000s, the BBC also used LaserDisc technology to play out the channel idents.
Which country still exported players to North America until 2001?
The answer is the following:
Japan
