Question: 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?

Answer: The Wharton School


Question: Passage: Iranian art encompasses many disciplines, including architecture, painting, weaving, pottery, calligraphy, metalworking, and stonemasonry. The Median and Achaemenid empires left a significant classical art scene which remained as basic influences for the art of the later eras. Art of the Parthians was a mixture of Iranian and Hellenistic artworks, with their main motifs being scenes of royal hunting expeditions and investitures. The Sassanid art played a prominent role in the formation of both European and Asian medieval art, which carried forward to the Islamic world, and much of what later became known as Islamic learning, such as philology, literature, jurisprudence, philosophy, medicine, architecture, and science, were of Sassanid basis. Question: The Achaemind Empire along with what other group became the foundation for the art in later Iranian history?

Answer: The Median


Question: Passage: For example, one might refer to the A above middle C as a', A4, or 440 Hz. In standard Western equal temperament, the notion of pitch is insensitive to "spelling": the description "G4 double sharp" refers to the same pitch as A4; in other temperaments, these may be distinct pitches. Human perception of musical intervals is approximately logarithmic with respect to fundamental frequency: the perceived interval between the pitches "A220" and "A440" is the same as the perceived interval between the pitches A440 and A880. Motivated by this logarithmic perception, music theorists sometimes represent pitches using a numerical scale based on the logarithm of fundamental frequency. For example, one can adopt the widely used MIDI standard to map fundamental frequency, f, to a real number, p, as follows Question: The description "G4 double sharp" refers to the same pitch as what?

Answer:
A4
