Problem: St. John%27s, Newfoundland and Labrador:

The economy has been growing quickly in recent years. In both 2010 and 2011, the metro area's gross domestic product (GDP) led 27 other metropolitan areas in the country, according to the Conference Board of Canada, recording growth of 6.6 per cent and 5.8 per cent respectively. At $52,000 the city's per capita GDP is the second highest out of all major Canadian cities. Economic forecasts suggest that the city will continue its strong economic growth in the coming years not only in the "oceanic" industries mentioned above, but also in tourism and new home construction as the population continues to grow. In May 2011, the city's unemployment rate fell to 5.6 per cent, the second lowest unemployment rate for a major city in Canada.

What was the city's unemployment rate in May 2011?
---
A: 5.6 per cent

Problem: Linking the information back together is the key to this system. In the relational model, some bit of information was used as a "key", uniquely defining a particular record. When information was being collected about a user, information stored in the optional tables would be found by searching for this key. For instance, if the login name of a user is unique, addresses and phone numbers for that user would be recorded with the login name as its key. This simple "re-linking" of related data back into a single collection is something that traditional computer languages are not designed for.
What is a key used for?

Answer: uniquely defining a particular record

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The deliberate separation of the Luftwaffe from the rest of the military structure encouraged the emergence of a major "communications gap" between Hitler and the Luftwaffe, which other factors helped to exacerbate. For one thing, Goring's fear of Hitler led him to falsify or misrepresent what information was available in the direction of an uncritical and over-optimistic interpretation of air strength. When Goring decided against continuing Wever's original heavy bomber programme in 1937, the Reichsmarschall's own explanation was that Hitler wanted to know only how many bombers there were, not how many engines each had. In July 1939, Goring arranged a display of the Luftwaffe's most advanced equipment at Rechlin, to give the impression the air force was more prepared for a strategic air war than was actually the case.
In what city did Goring display the advance equipment?
A: Rechlin

Context and question: Starting with Republican Nicholas Longworth in 1925, and continued through the Democrats' control of the House from 1931 to 1995, save for Republican majorities in 194749 and 195355, all majority leaders have directly ascended to the Speakership brought upon by the retirement of the incumbent. The only exceptions during this period were Charles A. Halleck who became Republican House leader and Minority Leader from 1959 to 1965, Hale Boggs who died in a plane crash, and Dick Gephardt who became the Democrats' House leader but as Minority Leader since his party lost control in the 1994 midterm elections. Since 1995, the only Majority Leader to become Speaker is John Boehner, though indirectly as his party lost control in the 2006 midterms elections. He subsequently served as Republican House leader and Minority Leader from 2007 to 2011 and then was elected Speaker when the House reconvened in 2011. In 1998, with Speaker Newt Gingrich announcing his resignation, both Majority Leader Dick Armey and Majority Whip Tom DeLay did not contest the Speakership which eventually went to Chief Deputy Whip Dennis Hastert.
Who succeeded Newt Gingrich as Speaker?
Answer: Dennis Hastert

Question: In a course at the LSA summer institute in 1991, Alan Prince and Paul Smolensky developed optimality theoryan overall architecture for phonology according to which languages choose a pronunciation of a word that best satisfies a list of constraints ordered by importance; a lower-ranked constraint can be violated when the violation is necessary in order to obey a higher-ranked constraint. The approach was soon extended to morphology by John McCarthy and Alan Prince, and has become a dominant trend in phonology. The appeal to phonetic grounding of constraints and representational elements (e.g. features) in various approaches has been criticized by proponents of 'substance-free phonology', especially Mark Hale and Charles Reiss.
Is there an answer to this question: Aside from Alan Prince who brought dominant theory to morphology?

Answer: unanswerable

Problem: Web browser:

In the case of http, https, file, and others, once the resource has been retrieved the web browser will display it. HTML and associated content (image files, formatting information such as CSS, etc.) is passed to the browser's layout engine to be transformed from markup to an interactive document, a process known as "rendering". Aside from HTML, web browsers can generally display any kind of content that can be part of a web page. Most browsers can display images, audio, video, and XML files, and often have plug-ins to support Flash applications and Java applets. Upon encountering a file of an unsupported type or a file that is set up to be downloaded rather than displayed, the browser prompts the user to save the file to disk.

Browsers have you save to disk so they can support what?
