Problem: New Delhi:

It took about 20 years to build the city from 1911. Many elements of New Delhi architecture borrow from indigenous sources; however, they fit into a British Classical/Palladian tradition. The fact that there were any indigenous features in the design were due to the persistence and urging of both the Viceroy Lord Hardinge and historians like E.B. Havell.

Many of the architectural elements of New Delhi borrow from what sources?

A: indigenous


Problem: Incandescent light bulb:

In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.

Who purchased the rights to the tantalum light filament from Siemens?
---
A: General Electric


Problem: Antarctica:

Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year.

What year did Trinity Orthodox open?

A: unanswerable


Problem: Literature:

The value judgement definition of literature considers it to exclusively include writing that possesses high quality or distinction, forming part of the so-called belles-lettres ('fine writing') tradition. This is the definition used in the Encyclopædia Britannica Eleventh Edition (1910–11) when it classifies literature as "the best expression of the best thought reduced to writing." However, this has the result that there is no objective definition of what constitutes "literature"; anything can be literature, and anything which is universally regarded as literature has the potential to be excluded, since value-judgements can change over time.

How does the 1901 Encyclopedia Britannica define "literature?"
