Problem: 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.
When did the idea of a "consumer society" begin?
The answer is the following: at the turn of the 19th century.

Problem: By the early 1940s, the company was concentrating on lower-budget productions that were the company's main staple: westerns, melodramas, serials and sequels to the studio's horror pictures, the latter now solely B pictures. The studio fostered many series: The Dead End Kids and Little Tough Guys action features and serials (193843); the comic adventures of infant Baby Sandy (193841); comedies with Hugh Herbert (193842) and The Ritz Brothers (194043); musicals with Robert Paige, Jane Frazee, The Andrews Sisters, and The Merry Macs (193845); and westerns with Tom Mix (193233), Buck Jones (193336), Bob Baker (193839), Johnny Mack Brown (193843); Rod Cameron (194445), and Kirby Grant (194647).
In what span did Universal produce westerns with Kirby Grant?
The answer is the following: 194647

Problem: In 1957, the state of Arkansas refused to honor a federal court order to integrate their public school system stemming from the Brown decision. Eisenhower demanded that Arkansas governor Orval Faubus obey the court order. When Faubus balked, the president placed the Arkansas National Guard under federal control and sent in the 101st Airborne Division. They escorted and protected nine black students' entry to Little Rock Central High School, an all-white public school, for the first time since the Reconstruction Era. Martin Luther King Jr. wrote to Eisenhower to thank him for his actions, writing "The overwhelming majority of southerners, Negro and white, stand firmly behind your resolute action to restore law and order in Little Rock".
What Arkansas militia unit did Eisenhower federalize in 1957?
The answer is the following: Arkansas National Guard

Problem: Service trials demonstrated another problem however: that ranging and tracking the new high-speed targets was almost impossible. At short range, the apparent target area is relatively large, the trajectory is flat and the time of flight is short, allowing to correct lead by watching the tracers. At long range, the aircraft remains in firing range for a long time, so the necessary calculations can in theory be done by slide rules - though, because small errors in distance cause large errors in shell fall height and detonation time, exact ranging is crucial. For the ranges and speeds that the Bofors worked at, neither answer was good enough.
What was shown to be practically not possible during service trials?
The answer is the following:
ranging and tracking the new high-speed targets
