QUES: The city has a unique status in Brazil, as it is an administrative division rather than a legal municipality like other cities in Brazil. The name 'Brasilia' is commonly used as a synonym for the Federal District through synecdoche; However, the Federal District is composed of 31 administrative regions, only one of which is Brasilia proper, with a population of 209,926 in a 2011 survey; Demographic publications generally do not make this distinction and list the population of Brasilia as synonymous with the population of the Federal District, considering the whole of it as its metropolitan area. The city was one of the main host cities of the 2014 FIFA World Cup. Additionally, Brasilia hosted the 2013 FIFA Confederations Cup.

How many administrative regions does the Federal District have?
What is the answer?

QUES: The first known smelting of iron began in Anatolia, around 1800 BC. Called the bloomery process, it produced very soft but ductile wrought iron. By 800 BC, iron-making technology had spread to Europe, arriving in Japan around 700 AD. Pig iron, a very hard but brittle alloy of iron and carbon, was being produced in China as early as 1200 BC, but did not arrive in Europe until the Middle Ages. Pig iron has a lower melting point than iron, and was used for making cast-iron. However, these metals found little practical use until the introduction of crucible steel around 300 BC. These steels were of poor quality, and the introduction of pattern welding, around the 1st century AD, sought to balance the extreme properties of the alloys by laminating them, to create a tougher metal. Around 700 AD, the Japanese began folding bloomery-steel and cast-iron in alternating layers to increase the strength of their swords, using clay fluxes to remove slag and impurities. This method of Japanese swordsmithing produced one of the purest steel-alloys of the early Middle Ages.

Pig iron is composed of iron and what else?
What is the answer?
ANS: carbon
QUES: Notwithstanding these technical and commercial successes on the Macintosh platform, their systems remained fairly expensive, making them less competitive in light of the falling costs of components that made IBM PC compatibles cheaper and accelerated their adoption. In 1989, Jean-Louis Gassee had steadfastly refused to lower the profit margins on Mac computers, then there was a component shortage that rocked the exponentially-expanding PC industry that year, forcing Apple USA head Allan Loren to cut prices which dropped Apple's margins. Microsoft Windows 3.0 was released in May 1990, the first iteration of Windows which had a feature set and performance comparable to the significantly costlier Macintosh. Furthermore, Apple had created too many similar models that confused potential buyers; at one point the product lineup was subdivided into Classic, LC, II, Quadra, Performa, and Centris models, with essentially the same computer being sold under a number of different names.
