QUES: The origins of the department store lay in the growth of the conspicuous consumer society at the turn of the 19th century. As the Industrial Revolution accelerated economy expansion, the affluent middle-class grew in size and wealth. This urbanized social group, sharing a culture of consumption and changing fashion, was the catalyst for the retail revolution. As rising prosperity and social mobility increased the number of people, especially women (who found they could shop unaccompanied at department stores without damaging their reputation), with disposable income in the late Georgian period, window shopping was transformed into a leisure activity and entrepreneurs, like the potter Josiah Wedgwood, pioneered the use of marketing techniques to influence the prevailing tastes and preferences of society.
What is one explanation for the rise of retail stores in earlier history?

ANS: urbanized social group

QUES: In 1260, control passed to the Mamluk sultans of Egypt. The country was located between the two centres of Mamluk power, Cairo and Damascus, and only saw some development along the postal road connecting the two cities. Jerusalem, although left without the protection of any city walls since 1219, also saw a flurry of new construction projects centred around the Al-Aqsa Mosque compound (the Temple Mount). In 1266 the Mamluk Sultan Baybars converted the Cave of the Patriarchs in Hebron into an exclusive Islamic sanctuary and banned Christians and Jews from entering, which previously would be able to enter it for a fee. The ban remained in place until Israel took control of the building in 1967.
What two centres of Mamluk power was the country located?

ANS: Cairo and Damascus

QUES: On October 21, 2008, Apple reported that only 14.21% of total revenue for fiscal quarter 4 of year 2008 came from iPods. At the September 9, 2009 keynote presentation at the Apple Event, Phil Schiller announced total cumulative sales of iPods exceeded 220 million. The continual decline of iPod sales since 2009 has not been a surprising trend for the Apple corporation, as Apple CFO Peter Oppenheimer explained in June 2009: "We expect our traditional MP3 players to decline over time as we cannibalize ourselves with the iPod Touch and the iPhone." Since 2009, the company's iPod sales have continually decreased every financial quarter and in 2013 a new model was not introduced onto the market.
From what year did iPod purchases begin to continuously decline?

ANS: 2009

QUES: In 1930, Paul Dirac proposed a model of the vacuum as an infinite sea of particles possessing negative energy, called the Dirac sea. This theory helped refine the predictions of his earlier formulated Dirac equation, and successfully predicted the existence of the positron, confirmed two years later. Werner Heisenberg's uncertainty principle formulated in 1927, predict a fundamental limit within which instantaneous position and momentum, or energy and time can be measured. This has far reaching consequences on the "emptiness" of space between particles. In the late 20th century, so-called virtual particles that arise spontaneously from empty space were confirmed.
What did Heisenberg call the particles with negative energy inside a vacuum?

ANS:
unanswerable
