[EX Q]: Passage: John Cotton and Anne Hutchinson regarded preparationism as a covenant of works, a criticism that was one of the causes of the Antinomian Controversy, which led to Hutchinson being banished from the Massachusetts Bay Colony in 1638. Historians have debated the factors in Hutchinson's downfall, including issues of politics and gender; but intellectual historians have focused on theological factors, including preparationism, antinomianism, mortalism, and the idea of sanctification being evidence of justification. Harvard University historian Perry Miller views the incident as a "dispute over the place of unregenerate human activity, or 'natural ability', preparatory to saving conversion." Similarly, Rhys Bezzant sees the Antinomian crisis as pitting Hutchinson and others against "the defenders of preparationist piety." Bezzant goes on to argue that Jonathan Edwards distanced himself from his grandfather Solomon Stoddard's "preparationist model of conversion."

[EX Q]: Passage: The Dublin Grand Opera Society (DGOS) was founded in 1941 by Captain (later Colonel) William O'Kelly and a group of opera enthusiasts with John McCormack as its patron. The shows were cast with local singers and a volunteer chorus. Initially the music was provided by the orchestra of the Irish Army music school, and later by the Radio Eireann Symphony Orchestra. The Society put on two one-week seasons of opera throughout the years of World War II. After the war ended the DGOS presented performances by European opera companies such as the Opera-Comique, Hamburg Opera and the Netherlands Opera. From the mid 1950s to 1966, the Society, concentrated on Italian opera with the help of sponsorship from the Italian government. During that time numerous Italian stars and rising stars of the day appeared there, including Luciano Pavarotti who sang in Rigoletto, La traviata, and La boheme. The Italian sponsorship ended in 1966, but the Arts Council of Ireland and the Bord Failte (Ireland's tourist board) continued to provide guarantees for any financial losses. New opera companies were brought in, including the Romanian National Opera and the Prague National Theatre.
