PROBLEM: Passage: Another important factor is the apparent consensus among Western great powers that military force is no longer an effective tool of resolving disputes among their peers. This "subset" of great powers – France, Germany, Japan, the United Kingdom and the United States – consider maintaining a "state of peace" as desirable. As evidence, Baron outlines that since the Cuban missile crisis (1962) during the Cold War, these influential Western nations have resolved all disputes among the great powers peacefully at the United Nations and other forums of international discussion.

SOLUTION: What countries agree that military force is effective to resolve disputes?

PROBLEM: 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.

SOLUTION: What are some present day Christian churces nolonger use the a capella form?

PROBLEM: Passage: Americans of English descent and Americans of Scots-Irish descent began moving into northern Florida from the backwoods of Georgia and South Carolina. Though technically not allowed by the Spanish authorities, the Spanish were never able to effectively police the border region and the backwoods settlers from the United States would continue to migrate into Florida unchecked. These migrants, mixing with the already present British settlers who had remained in Florida since the British period, would be the progenitors of the population known as Florida Crackers.

SOLUTION:
Where did the Spanish patrol well?
