Problem: Dutch language:

Three Germanic dialects were originally spoken in the Low Countries: Frisian in the north and along the western coast; Saxon in the east (contiguous with the Low German area); and Franconian in the centre and south. It is the Franconian dialects that is designated as Old Dutch, and that would develop in Middle Dutch and later Modern Dutch. The division in these development phases is mostly conventional, since the transition between them was very gradual. One of the few moments linguists can detect somewhat of a revolution is when the Dutch standard language emerged and quickly established itself. The development of the Dutch language is illustrated by the following sentence in Old, Middle and Modern Dutch:

Which dialects are referred to as "Old Dutch"?
---
A: Franconian


Problem: Frédéric Chopin:

In 1817 the Saxon Palace was requisitioned by Warsaw's Russian governor for military use, and the Warsaw Lyceum was reestablished in the Kazimierz Palace (today the rectorate of Warsaw University). Fryderyk and his family moved to a building, which still survives, adjacent to the Kazimierz Palace. During this period, Fryderyk was sometimes invited to the Belweder Palace as playmate to the son of the ruler of Russian Poland, Grand Duke Constantine; he played the piano for the Duke and composed a march for him. Julian Ursyn Niemcewicz, in his dramatic eclogue, "Nasze Przebiegi" ("Our Discourses", 1818), attested to "little Chopin's" popularity.

What palace was Frédéric sometimes invited to as a companion of the ruler's son?
---
A: Belweder Palace


Problem: Adult contemporary music:

In the 1980s, lush jazz-R&B fusion (George Benson, Patti Austin, Al Jarreau) and stylish crossover R&B (Anita Baker and Luther Vandross, New Edition and Keith Sweat) were equally successful within the mainstream. In the 1990s and early 2000s (decade), artists as sonically contrasting as R. Kelly, Leona Lewis (mainly ballads) and Jill Scott both fit the bill, provided the audience for the material was mature. By riding and contributing to nearly all of the trends, no one has exemplified the style more than Babyface, whose career thrived over 20 years as a member of the Deele (Two Occasions), a solo artist (Whip Appeal, When Can I See You), and a songwriter/producer (Toni Braxton's Breathe Again, Boyz II Men's I'll Make Love to You).

What type of songs was Leona Lewis known for?
---
A: ballads


Problem: Textual criticism:

The textual critic's ultimate objective is the production of a "critical edition".[citation needed] This contains the text that the author has determined most closely approximates the original, and is accompanied by an apparatus criticus or critical apparatus. The critical apparatus presents the author's work in three parts: first, a list or description of the evidence that the editor used (names of manuscripts, or abbreviations called sigla); second, the editor's analysis of that evidence (sometimes a simple likelihood rating),[citation needed]; and third, a record of rejected variants of the text (often in order of preference).[citation needed]

What is included in or accompanies in "critical edition"?
---
A:
apparatus criticus or critical apparatus
