Article: Founded at various times in the university's history, the professional schools originally were scattered throughout Chicago. In connection with a 1917 master plan for a central Chicago campus and President Walter Dill Scott's capital campaign, 8.5 acres (3.44 ha) of land were purchased at the corner of Chicago Avenue and Lake Shore Drive for $1.5 million in 1920. The architect James Gamble Rogers was commissioned to create a master plan for the principal buildings on the new campus which he designed in collegiate gothic style. In 1923, Mrs. Montgomery Ward donated $8 million to the campaign to finance the construction of the Montgomery Ward Memorial Building which would house the medical and dental schools and to create endowments for faculty chairs, research grants, scholarships, and building maintenance. The building would become the first university skyscraper in the United States. In addition to the Ward Building, Rogers designed Wieboldt Hall to house facilities for the School of Commerce and Levy Mayer Hall to house the School of Law. The new campus comprising these three new buildings was dedicated during a two-day ceremony in June 1927. The Chicago campus continued to expand with the addition of Thorne Hall in 1931 and Abbott Hall in 1939. In October 2013, Northwestern began the demolition of the architecturally significant Prentice Women's Hospital. Eric G. Neilson, dean of the medical school, penned an op-ed that equated retaining the building with loss of life.

Article: Several notable video game developers criticized Microsoft for making its Windows Store a closed platform subject to its own regulations, as it conflicted with their view of the PC as an open platform. Markus "Notch" Persson (creator of the indie game Minecraft), Gabe Newell (co-founder of Valve Corporation and developer of software distribution platform Steam), and Rob Pardo from Activision Blizzard voiced concern about the closed nature of the Windows Store. However, Tom Warren of The Verge stated that Microsoft's addition of the Store was simply responding to the success of both Apple and Google in pursuing the "curated application store approach."

Article: German historian Reinhart Koselleck claimed that "On the Continent there were two social structures that left a decisive imprint on the Age of Enlightenment: the Republic of Letters and the Masonic lodges." Scottish professor Thomas Munck argues that "although the Masons did promote international and cross-social contacts which were essentially non-religious and broadly in agreement with enlightened values, they can hardly be described as a major radical or reformist network in their own right." Many of the Masons values seemed to greatly appeal to Enlightenment values and thinkers. Diderot discusses the link between Freemason ideals and the enlightenment in D'Alembert's Dream, exploring masonry as a way of spreading enlightenment beliefs. Historian Margaret Jacob stresses the importance of the Masons in indirectly inspiring enlightened political thought. On the negative side, Daniel Roche contests claims that Masonry promoted egalitarianism. He argues that the lodges only attracted men of similar social backgrounds. The presence of noble women in the French "lodges of adoption" that formed in the 1780s was largely due to the close ties shared between these lodges and aristocratic society.

Question: According to German historian Reinhart Koselleck, which two social structures left a decisive imprint on the Age of Enlightenment?
Ans:
the Republic of Letters and the Masonic lodges
