Problem: Miami:

Downtown Miami is home to the largest concentration of international banks in the United States, and many large national and international companies. The Civic Center is a major center for hospitals, research institutes, medical centers, and biotechnology industries. For more than two decades, the Port of Miami, known as the "Cruise Capital of the World", has been the number one cruise passenger port in the world. It accommodates some of the world's largest cruise ships and operations, and is the busiest port in both passenger traffic and cruise lines.

Along with cruise lines, in what traffic does Miami's port rank last?

Problem: In England, partly in response to a philosophy propounded by the Oxford Movement and others associated with the emerging revival of 'high church' or Anglo-Catholic ideas during the second quarter of the 19th century, neo-Gothic began to become promoted by influential establishment figures as the preferred style for ecclesiastical, civic and institutional architecture. The appeal of this Gothic revival (which after 1837, in Britain, is sometimes termed Victorian Gothic), gradually widened to encompass "low church" as well as "high church" clients. This period of more universal appeal, spanning 18551885, is known in Britain as High Victorian Gothic.
When was neo-Gothic popularized by influential figures?

Answer: during the second quarter of the 19th century

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Being Sicily's administrative capital, Palermo is a centre for much of the region's finance, tourism and commerce. The city currently hosts an international airport, and Palermo's economic growth over the years has brought the opening of many new businesses. The economy mainly relies on tourism and services, but also has commerce, shipbuilding and agriculture. The city, however, still has high unemployment levels, high corruption and a significant black market empire (Palermo being the home of the Sicilian Mafia). Even though the city still suffers from widespread corruption, inefficient bureaucracy and organized crime, the level of crime in Palermo's has gone down dramatically, unemployment has been decreasing and many new, profitable opportunities for growth (especially regarding tourism) have been introduced, making the city safer and better to live in.
What has made the city more dangerouse to live in?
A: unanswerable

Context and question: The softness of copper partly explains its high electrical conductivity (59.6106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur.
What metal has a higher thermal conductivity than copper?
Answer: silver

Question: Glacial bodies larger than 50,000 km2 (19,000 sq mi) are called ice sheets or continental glaciers. Several kilometers deep, they obscure the underlying topography. Only nunataks protrude from their surfaces. The only extant ice sheets are the two that cover most of Antarctica and Greenland. They contain vast quantities of fresh water, enough that if both melted, global sea levels would rise by over 70 m (230 ft). Portions of an ice sheet or cap that extend into water are called ice shelves; they tend to be thin with limited slopes and reduced velocities. Narrow, fast-moving sections of an ice sheet are called ice streams. In Antarctica, many ice streams drain into large ice shelves. Some drain directly into the sea, often with an ice tongue, like Mertz Glacier.
Is there an answer to this question: What are glaciers smaller it in 50,000 km called?

Answer: unanswerable

Question: The creation of a modern industrial economy took place. With the creation of a transportation and communication infrastructure, the corporation became the dominant form of business organization and a managerial revolution transformed business operations. In 1890, Congress passed the Sherman Antitrust Actthe source of all American anti-monopoly laws. The law forbade every contract, scheme, deal, or conspiracy to restrain trade, though the phrase "restraint of trade" remained subjective. By the beginning of the 20th century, per capita income and industrial production in the United States exceeded that of any other country except Britain. Long hours and hazardous working conditions led many workers to attempt to form labor unions despite strong opposition from industrialists and the courts. But the courts did protect the marketplace, declaring the Standard Oil group to be an "unreasonable" monopoly under the Sherman Antitrust Act in 1911. It ordered Standard to break up into 34 independent companies with different boards of directors.
Is there an answer to this question: What became the dominant form of business organization?

Answer:
the corporation
