Input: Film speed
Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.

What happens outside the 1/1000 second to 1/second exposure range?
Output: reciprocity failure

Input: Article: Miami International Airport and PortMiami are among the nation's busiest ports of entry, especially for cargo from South America and the Caribbean. The Port of Miami is the world's busiest cruise port, and MIA is the busiest airport in Florida, and the largest gateway between the United States and Latin America. Additionally, the city has the largest concentration of international banks in the country, primarily along Brickell Avenue in Brickell, Miami's financial district. Due to its strength in international business, finance and trade, many international banks have offices in Downtown such as Espirito Santo Financial Group, which has its U.S. headquarters in Miami. Miami was also the host city of the 2003 Free Trade Area of the Americas negotiations, and is one of the leading candidates to become the trading bloc's headquarters.

Now answer this question: What street is central to the financial district of Miami?

Output: Brickell Avenue

Article: As a result of the magnitude 7.9 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes" behind the blockages; these massive amounts of water were pooling up at a very high rate behind the natural landslide dams and it was feared that the blockages would eventually crumble under the weight of the ever-increasing water mass, potentially endangering the lives of millions of people living downstream. As of May 27, 2008, 34 lakes had formed due to earthquake debris blocking and damming rivers, and it was estimated that 28 of them were still of potential danger to the local people. Entire villages had to be evacuated because of the resultant flooding.

Question: What had to be evacuated due to potential flooding?
Ans: Entire villages

Here is a question about this article: Melbourne has the largest tram network in the world which had its origins in the city's 1880s land boom. In 20132014, 176.9 million passenger trips were made by tram. Melbourne's is Australia's only tram network to comprise more than a single line and consists of 250 km (155.3 mi) of track, 487 trams, 25 routes, and 1,763 tram stops. Around 80 per cent of Melbourne's tram network shares road space with other vehicles, while the rest of the network is separated or are light rail routes. Melbourne's trams are recognised as iconic cultural assets and a tourist attraction. Heritage trams operate on the free City Circle route, intended for visitors to Melbourne, and heritage restaurant trams travel through the city and surrounding areas during the evening. Melbourne is currently building 50 new E Class trams with some already in service in 2014. The E Class trams are about 30 metres long and are superior to the C2 class tram of similar length. Melbourne's bus network consists of almost 300 routes which mainly service the outer suburbs and fill the gaps in the network between rail and tram services. 127.6 million passenger trips were recorded on Melbourne's buses in 20132014, an increase of 10.2 percent on the previous year.
What is the answer to this question: What are the origins of Melbourne's tram network?
****
So... the city's 1880s land boom
