[EX Q]: Passage: A cover story in BusinessWeek magazine claims that economists mostly failed to predict the worst international economic crisis since the Great Depression of the 1930s. The Wharton School of the University of Pennsylvania's online business journal examines why economists failed to predict a major global financial crisis. Popular articles published in the mass media have led the general public to believe that the majority of economists have failed in their obligation to predict the financial crisis. For example, an article in the New York Times informs that economist Nouriel Roubini warned of such crisis as early as September 2006, and the article goes on to state that the profession of economics is bad at predicting recessions. According to The Guardian, Roubini was ridiculed for predicting a collapse of the housing market and worldwide recession, while The New York Times labelled him "Dr. Doom". Question: Which school at University of Pennsylvania examined in their online business journal why economists failed to predict the crisis?
[EX A]: The Wharton School

[EX Q]: Passage: Kenneth Gergen formulated additional classifications, which include the strategic manipulator, the pastiche personality, and the relational self. The strategic manipulator is a person who begins to regard all senses of identity merely as role-playing exercises, and who gradually becomes alienated from his or her social "self". The pastiche personality abandons all aspirations toward a true or "essential" identity, instead viewing social interactions as opportunities to play out, and hence become, the roles they play. Finally, the relational self is a perspective by which persons abandon all sense of exclusive self, and view all sense of identity in terms of social engagement with others. For Gergen, these strategies follow one another in phases, and they are linked to the increase in popularity of postmodern culture and the rise of telecommunications technology. Question: In what classification is a person who regards all experiences are role play and becomes alienated from his or her social self?
[EX A]: The strategic manipulator

[EX Q]: Passage: In the Low Middle Ages, Catalan went through a golden age, reaching a peak of maturity and cultural richness. Examples include the work of Majorcan polymath Ramon Llull (1232–1315), the Four Great Chronicles (13th–14th centuries), and the Valencian school of poetry culminating in Ausiàs March (1397–1459). By the 15th century, the city of Valencia had become the sociocultural center of the Crown of Aragon, and Catalan was present all over the Mediterranean world. During this period, the Royal Chancery propagated a highly standardized language. Catalan was widely used as an official language in Sicily until the 15th century, and in Sardinia until the 17th. During this period, the language was what Costa Carreras terms "one of the 'great languages' of medieval Europe". Question: Until what century was Catalan used as the official language in Sardinia?
[EX A]:
17th
