Problem: 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.

Problem: Many ancient works, such as the Bible and the Greek tragedies,[citation needed] survive in hundreds of copies, and the relationship of each copy to the original may be unclear. Textual scholars have debated for centuries which sources are most closely derived from the original, hence which readings in those sources are correct.[citation needed] Although biblical books that are letters, like Greek plays, presumably had one original, the question of whether some biblical books, like the Gospels, ever had just one original has been discussed. Interest in applying textual criticism to the Qur'an has also developed after the discovery of the Sana'a manuscripts in 1972, which possibly date back to the 78th centuries.
Interest in an analysis of what text has arose in the early 8th century?
