Article: The halogen lamp reduces uneven evaporation of the filament and eliminates darkening of the envelope by filling the lamp with a halogen gas at low pressure, rather than an inert gas. The halogen cycle increases the lifetime of the bulb and prevents its darkening by redepositing tungsten from the inside of the bulb back onto the filament. The halogen lamp can operate its filament at a higher temperature than a standard gas filled lamp of similar power without loss of operating life. Such bulbs are much smaller than normal incandescent bulbs, and are widely used where intense illumination is needed in a limited space. Fiber-optic lamps for optical microscopy is one typical application.

Question: What is the most common situation when a halogen bulb is used?
Ans: where intense illumination is needed in a limited space

The problem: Answer a question about this article:
After an initial loss to Labor at the 1946 election, Menzies led the Liberals to victory at the 1949 election, and the party stayed in office for a record 23 years—still the longest unbroken run in government at the federal level. Australia experienced prolonged economic growth during the post-war boom period of the Menzies Government (1949–1966) and Menzies fulfilled his promises at the 1949 election to end rationing of butter, tea and petrol and provided a five-shilling endowment for first-born children, as well as for others. While himself an unashamed anglophile, Menzies' government concluded a number of major defence and trade treaties that set Australia on its post-war trajectory out of Britain's orbit; opened Australia to multi-ethnic immigration; and instigated important legal reforms regarding Aboriginal Australians.
During what period did Australia experience long-term economic growth?
****
The answer: the post-war boom period of the Menzies Government (1949–1966)

On 30 March, Nasser proclaimed a manifesto stipulating the restoration of civil liberties, greater parliamentary independence from the executive, major structural changes to the ASU, and a campaign to rid the government of corrupt elements.

How did Nasser want to change the relationship between parliament and the executive?
A: independence

Integral to the story of the origin of the name "Antarctica" is how it was not named Terra Australis—this name was given to Australia instead, and it was because of a mistake made by people who decided that a significant landmass would not be found farther south than Australia. Explorer Matthew Flinders, in particular, has been credited with popularizing the transfer of the name Terra Australis to Australia. He justified the titling of his book A Voyage to Terra Australis (1814) by writing in the introduction:

In what year did Matthew Flinders write his book A Voyage to Terra Australis?
Answer: 1814
