Problem: Gothic architecture:

Romanesque architecture in Germany, Poland, the Czech Lands and Austria is characterised by its massive and modular nature. This is expressed in the Gothic architecture of Central Europe in the huge size of the towers and spires, often projected, but not always completed. The west front generally follows the French formula, but the towers are very much taller and, if complete, are surmounted by enormous openwork spires that are a regional feature. Because of the size of the towers, the section of the facade between them may appear narrow and compressed. The eastern end follows the French form. The distinctive character of the interior of German Gothic cathedrals is their breadth and openness. This is the case even when, as at Cologne, they have been modelled upon a French cathedral. German cathedrals, like the French, tend not to have strongly projecting transepts. There are also many hall churches (Hallenkirchen) without clerestory windows.

What are hall churches in German cathedrals no longer known as?

Problem: In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
Did the US Congress call for more or less regulation of pharmaceuticals?

Answer: greater

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The relational model also allowed the content of the database to evolve without constant rewriting of links and pointers. The relational part comes from entities referencing other entities in what is known as one-to-many relationship, like a traditional hierarchical model, and many-to-many relationship, like a navigational (network) model. Thus, a relational model can express both hierarchical and navigational models, as well as its native tabular model, allowing for pure or combined modeling in terms of these three models, as the application requires.
What is the relationship that is avoided in a navigational model?
A: unanswerable

Context and question: In agriculture and animal husbandry, the Green Revolution popularized the use of conventional hybridization to increase yield. Often hybridized breeds originated in developed countries and were further hybridized with local varieties in the developing world to create high yield strains resistant to local climate and diseases. Local governments and industry have been pushing hybridization. Formerly huge gene pools of various wild and indigenous breeds have collapsed causing widespread genetic erosion and genetic pollution. This has resulted in loss of genetic diversity and biodiversity as a whole.
Who has been pushing for hybridization?
Answer: Local governments and industry

Question: Today, thanks to Paris' cosmopolitan population, every French regional cuisine and almost every national cuisine in the world can be found there; the city has more than 9,000 restaurants. The Michelin Guide has been a standard guide to French restaurants since 1900, awarding its highest award, three stars, to the best restaurants in France. In 2015, of the 29 Michelin three-star restaurants in France, nine are located in Paris. These include both restaurants which serve classical French cuisine, such as L'Ambroisie in the Place des Vosges, and those which serve non-traditional menus, such as L'Astrance, which combines French and Asian cuisines. Several of France's most famous chefs, including Pierre Gagnaire, Alain Ducasse, Yannick Alleno and Alain Passard, have three-star restaurants in Paris.
Is there an answer to this question: How many 3 star Michelin restaurants were in Paris in 2015?

Problem: New Haven, Connecticut:

In 1954, then-mayor Richard C. Lee began some of the earliest major urban renewal projects in the United States. Certain sections of downtown New Haven were redeveloped to include museums, new office towers, a hotel, and large shopping complexes. Other parts of the city were affected by the construction of Interstate 95 along the Long Wharf section, Interstate 91, and the Oak Street Connector. The Oak Street Connector (Route 34), running between Interstate 95, downtown, and The Hill neighborhood, was originally intended as a highway to the city's western suburbs but was only completed as a highway to the downtown area, with the area to the west becoming a boulevard (See "Redevelopment" below).

What was the name of the mayor that lead the urban development project in New Haven 1954?

A:
Richard C. Lee
