Problem: Plymouth:

The 1971 Local Government White Paper proposed abolishing county boroughs, which would have left Plymouth, a town of 250,000 people, being administered from a council based at the smaller Exeter, on the other side of the county. This led to Plymouth lobbying for the creation of a Tamarside county, to include Plymouth, Torpoint, Saltash, and the rural hinterland. The campaign was not successful, and Plymouth ceased to be a county borough on 1 April 1974 with responsibility for education, social services, highways and libraries transferred to Devon County Council. All powers returned when the city become a unitary authority on 1 April 1998 under recommendations of the Banham Commission.

What body proposed that Plymouth become a unitary council?
---
A: the Banham Commission


Problem: The most recognizable icon of Mexico City is the golden Angel of Independence on the wide, elegant avenue Paseo de la Reforma, modeled by the order of the Emperor Maximilian of Mexico after the Champs-Élysées in Paris. This avenue was designed over the Americas' oldest known major roadway in the 19th century to connect the National Palace (seat of government) with the Castle of Chapultepec, the imperial residence. Today, this avenue is an important financial district in which the Mexican Stock Exchange and several corporate headquarters are located. Another important avenue is the Avenida de los Insurgentes, which extends 28.8 km (17.9 mi) and is one of the longest single avenues in the world.
What is the most popular icon of Mexico City?

Answer: golden Angel of Independence


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The city's total area is 468.9 square miles (1,214 km2). 164.1 sq mi (425 km2) of this is water and 304.8 sq mi (789 km2) is land. The highest point in the city is Todt Hill on Staten Island, which, at 409.8 feet (124.9 m) above sea level, is the highest point on the Eastern Seaboard south of Maine. The summit of the ridge is mostly covered in woodlands as part of the Staten Island Greenbelt.
In square miles, how much of the city's total area is land?
A: 304.8


Context and question: The court ruled in 2014, after lengthy testimony, that at least two districts had to be redrawn because of gerrymandering. After this was appealed, in July 2015 the Florida Supreme Court ruled that lawmakers had followed an illegal and unconstitutional process overly influenced by party operatives, and ruled that at least eight districts had to be redrawn. On December 2, 2015, a 5-2 majority of the Court accepted a new map of congressional districts, some of which was drawn by challengers. Their ruling affirmed the map previously approved by Leon County Judge Terry Lewis, who had overseen the original trial. It particularly makes changes in South Florida. There are likely to be additional challenges to the map and districts.
As of what date, the congressional maps are permanent?
Answer: unanswerable


Question: Furthermore, in the case of far-right, far-left and regionalism parties in the national parliaments of much of the European Union, mainstream political parties may form an informal cordon sanitarian which applies a policy of non-cooperation towards those "Outsider Parties" present in the legislature which are viewed as 'anti-system' or otherwise unacceptable for government. Cordon Sanitarian, however, have been increasingly abandoned over the past two decades in multi-party democracies as the pressure to construct broad coalitions in order to win elections – along with the increased willingness of outsider parties themselves to participate in government – has led to many such parties entering electoral and government coalitions.
Is there an answer to this question: What groups have Outsider Parties not wanted to cooperate with recently?

Answer: unanswerable


Problem: BeiDou Navigation Satellite System:

The investigation of the transmitted signals started immediately after the launch of Compass -M1 on 14 April 2007. Soon after in June 2007, engineers at CNES reported the spectrum and structure of the signals. A month later, researchers from Stanford University reported the complete decoding of the “I” signals components. The knowledge of the codes allowed a group of engineers at Septentrio to build the COMPASS receiver and report tracking and multipath characteristics of the “I” signals on E2 and E5B.

Knowing the codes allowed Stanford researchers to build the NERF receiver and report what?

A:
unanswerable
