Problem: Incandescent light bulb:

During ordinary operation, the tungsten of the filament evaporates; hotter, more-efficient filaments evaporate faster. Because of this, the lifetime of a filament lamp is a trade-off between efficiency and longevity. The trade-off is typically set to provide a lifetime of several hundred to 2,000 hours for lamps used for general illumination. Theatrical, photographic, and projection lamps may have a useful life of only a few hours, trading life expectancy for high output in a compact form. Long-life general service lamps have lower efficiency but are used where the cost of changing the lamp is high compared to the value of energy used.

What does not determine how fast a tungsten filament evaporates?

A: unanswerable

Problem: Advertising is common in healthcare journals as well as through more mainstream media routes. In some countries, notably the US, they are allowed to advertise directly to the general public. Pharmaceutical companies generally employ sales people (often called 'drug reps' or, an older term, 'detail men') to market directly and personally to physicians and other healthcare providers. In some countries, notably the US, pharmaceutical companies also employ lobbyists to influence politicians. Marketing of prescription drugs in the US is regulated by the federal Prescription Drug Marketing Act of 1987.
What is marketing of media in the US regulated by?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On the other hand, in his study on nine of "the Bibles most widely in use in the English-speaking world", Bible scholar Jason BeDuhn, Professor of Religious Studies at the Northern Arizona University, wrote: "The NW [New World Translation] emerges as the most accurate of the translations compared." Although the general public and many Bible scholars assume that the differences in the New World Translation are the result of religious bias on the part of its translators, BeDuhn stated: "Most of the differences are due to the greater accuracy of the NW as a literal, conservative translation of the original expressions of the New Testament writers." He added however that the insertion of the name Jehovah in the New Testament "violate[s] accuracy in favor of denominationally preferred expressions for God".
What do many Bible scholars assume the differences in the New World Translation are the result of?
A: religious bias

Context and question: Architectural interest in Cubism centered on the dissolution and reconstitution of three-dimensional form, using simple geometric shapes, juxtaposed without the illusions of classical perspective. Diverse elements could be superimposed, made transparent or penetrate one another, while retaining their spatial relationships. Cubism had become an influential factor in the development of modern architecture from 1912 (La Maison Cubiste, by Raymond Duchamp-Villon and Andre Mare) onwards, developing in parallel with architects such as Peter Behrens and Walter Gropius, with the simplification of building design, the use of materials appropriate to industrial production, and the increased use of glass.
In Cubism what was architechtural interested base on?
Answer: the dissolution and reconstitution of three-dimensional form

Question: In Northern Germany, Netherlands, northern Poland, Denmark, and the Baltic countries local building stone was unavailable but there was a strong tradition of building in brick. The resultant style, Brick Gothic, is called "Backsteingotik" in Germany and Scandinavia and is associated with the Hanseatic League. In Italy, stone was used for fortifications, but brick was preferred for other buildings. Because of the extensive and varied deposits of marble, many buildings were faced in marble, or were left with undecorated facade so that this might be achieved at a later date.
Is there an answer to this question: Why were many buildings covered with marble?

Answer: Because of the extensive and varied deposits of marble

Problem: England national football team:

The motif of the England national football team has three lions passant guardant, the emblem of King Richard I, who reigned from 1189 to 1199. The lions, often blue, have had minor changes to colour and appearance. Initially topped by a crown, this was removed in 1949 when the FA was given an official coat of arms by the College of Arms; this introduced ten Tudor roses, one for each of the regional branches of the FA. Since 2003, England top their logo with a star to recognise their World Cup win in 1966; this was first embroidered onto the left sleeve of the home kit, and a year later was moved to its current position, first on the away shirt.

What colour are the ten Tudor roses on England's shirts?
