[EX Q]: Passage: Much of the legislative style was adapted from the Roman Law Code of Justinian. As a result, Roman ecclesiastical courts tend to follow the Roman Law style of continental Europe with some variation, featuring collegiate panels of judges and an investigative form of proceeding, called "inquisitorial", from the Latin "inquirere", to enquire. This is in contrast to the adversarial form of proceeding found in the common law system of English and U.S. law, which features such things as juries and single judges.

[EX Q]: Passage: Present-day Christian religious bodies known for conducting their worship services without musical accompaniment include some Presbyterian churches devoted to the regulative principle of worship, Old Regular Baptists, Primitive Baptists, Plymouth Brethren, Churches of Christ, the Old German Baptist Brethren, Doukhobors the Byzantine Rite and the Amish, Old Order Mennonites and Conservative Mennonites. Certain high church services and other musical events in liturgical churches (such as the Roman Catholic Mass and the Lutheran Divine Service) may be a cappella, a practice remaining from apostolic times. Many Mennonites also conduct some or all of their services without instruments. Sacred Harp, a type of folk music, is an a cappella style of religious singing with shape notes, usually sung at singing conventions.

[EX Q]: Passage: The city has a unique status in Brazil, as it is an administrative division rather than a legal municipality like other cities in Brazil. The name 'Brasília' is commonly used as a synonym for the Federal District through synecdoche; However, the Federal District is composed of 31 administrative regions, only one of which is Brasília proper, with a population of 209,926 in a 2011 survey; Demographic publications generally do not make this distinction and list the population of Brasília as synonymous with the population of the Federal District, considering the whole of it as its metropolitan area. The city was one of the main host cities of the 2014 FIFA World Cup. Additionally, Brasília hosted the 2013 FIFA Confederations Cup.
