Problem: Political party:

When they lost power, the old Whig leadership dissolved into a decade of factional chaos with distinct "Grenvillite", "Bedfordite", "Rockinghamite", and "Chathamite" factions successively in power, and all referring to themselves as "Whigs". Out of this chaos, the first distinctive parties emerged. The first such party was the Rockingham Whigs under the leadership of Charles Watson-Wentworth and the intellectual guidance of the political philosopher Edmund Burke. Burke laid out a philosophy that described the basic framework of the political party as "a body of men united for promoting by their joint endeavours the national interest, upon some particular principle in which they are all agreed". As opposed to the instability of the earlier factions, which were often tied to a particular leader and could disintegrate if removed from power, the party was centred around a set of core principles and remained out of power as a united opposition to government.

What group was lead by Edmund Burke?

A: unanswerable

Problem: Classical music:

Given the wide range of styles in classical music, from Medieval plainchant sung by monks to Classical and Romantic symphonies for orchestra from the 1700s and 1800s to avant-garde atonal compositions for solo piano from the 1900s, it is difficult to list characteristics that can be attributed to all works of that type. However, there are characteristics that classical music contains that few or no other genres of music contain, such as the use of a printed score and the performance of very complex instrumental works (e.g., the fugue). As well, although the symphony did not exist through the entire classical music period, from the mid-1700s to the 2000s the symphony ensembleand the works written for ithave become a defining feature of classical music.

What has become a defining feature of classical music?
---
A: the symphony ensemble

Problem: States of Germany:

The governments in Berlin, Bremen and Hamburg are designated by the term Senate. In the three free states of Bavaria, Saxony, and Thuringia the government is referred to as the State Government (Staatsregierung), and in the other ten states the term Land Government (Landesregierung) is used. Before January 1, 2000, Bavaria had a bicameral parliament, with a popularly elected Landtag, and a Senate made up of representatives of the state's major social and economic groups. The Senate was abolished following a referendum in 1998. The states of Berlin, Bremen, and Hamburg are governed slightly differently from the other states. In each of those cities, the executive branch consists of a Senate of approximately eight, selected by the state's parliament; the senators carry out duties equivalent to those of the ministers in the larger states. The equivalent of the Minister-President is the Senatsprasident (President of the Senate) in Bremen, the Erster Burgermeister (First Mayor) in Hamburg, and the Regierender Burgermeister (Governing Mayor) in Berlin. The parliament for Berlin is called the Abgeordnetenhaus (House of Representatives), while Bremen and Hamburg both have a Burgerschaft. The parliaments in the remaining 13 states are referred to as Landtag (State Parliament).

The parliament in Berlin is called what?
---
A: Abgeordnetenhaus
