Problem: New York City:

In the 19th century, the city was transformed by development relating to its status as a trading center, as well as by European immigration. The city adopted the Commissioners' Plan of 1811, which expanded the city street grid to encompass all of Manhattan. The 1825 completion of the Erie Canal through central New York connected the Atlantic port to the agricultural markets and commodities of the North American interior via the Hudson River and the Great Lakes. Local politics became dominated by Tammany Hall, a political machine supported by Irish and German immigrants.

Along with German immigrants, immigrants of what nationality supported Tammany Hall?
---
A: Irish

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Georgian architecture was widely disseminated in the English colonies during the Georgian era. American buildings of the Georgian period were very often constructed of wood with clapboards; even columns were made of timber, framed up, and turned on an over-sized lathe. At the start of the period the difficulties of obtaining and transporting brick or stone made them a common alternative only in the larger cities, or where they were obtainable locally. Dartmouth College, Harvard University, and the College of William and Mary, offer leading examples of Georgian architecture in the Americas.
What material was rarely used for Georgian period American buildings?
A: unanswerable

Context and question: On 1 July 1967, BBC Two became the first television channel in Europe to broadcast regularly in colour, using the West German PAL system that is still in use today although being gradually superseded by digital systems. (BBC One and ITV began 625-line colour broadcasts simultaneously on 15 November 1969). Unlike other terrestrial channels, BBC Two does not have soap opera or standard news programming, but a range of programmes intended to be eclectic and diverse (although if a programme has high audience ratings it is often eventually repositioned to BBC One). The different remit of BBC2 allowed its first controller, Sir David Attenborough to commission the first heavyweight documentaries and documentary series such as Civilisation, The Ascent of Man and Horizon.
What kinds of programs did Attenborough favor?
Answer: documentaries

Question: Yale's museum collections are also of international stature. The Yale University Art Gallery, the country's first university-affiliated art museum, contains more than 180,000 works, including Old Masters and important collections of modern art, in the Swartout and Kahn buildings. The latter, Louis Kahn's first large-scale American work (1953), was renovated and reopened in December 2006. The Yale Center for British Art, the largest collection of British art outside of the UK, grew from a gift of Paul Mellon and is housed in another Kahn-designed building.
Is there an answer to this question: How many items aren't in The Yale University Art Gallery?

Answer: unanswerable

Problem: ASCII:

The committee considered an eight-bit code, since eight bits (octets) would allow two four-bit patterns to efficiently encode two digits with binary-coded decimal. However, it would require all data transmission to send eight bits when seven could suffice. The committee voted to use a seven-bit code to minimize costs associated with data transmission. Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.:217, 2365 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.

Why did the company decide on 9bit instead?
