Question: Passage: By August 1805, Napoleon had realized that the strategic situation had changed fundamentally. Facing a potential invasion from his continental enemies, he decided to strike first and turned his army's sights from the English Channel to the Rhine. His basic objective was to destroy the isolated Austrian armies in Southern Germany before their Russian allies could arrive. On 25 September, after great secrecy and feverish marching, 200,000 French troops began to cross the Rhine on a front of 260 km (160 mi). Austrian commander Karl Mack had gathered the greater part of the Austrian army at the fortress of Ulm in Swabia. Napoleon swung his forces to the southeast and the Grande Armee performed an elaborate wheeling movement that outflanked the Austrian positions. The Ulm Maneuver completely surprised General Mack, who belatedly understood that his army had been cut off. After some minor engagements that culminated in the Battle of Ulm, Mack finally surrendered after realizing that there was no way to break out of the French encirclement. For just 2000 French casualties, Napoleon had managed to capture a total of 60,000 Austrian soldiers through his army's rapid marching. The Ulm Campaign is generally regarded as a strategic masterpiece and was influential in the development of the Schlieffen Plan in the late 19th century. For the French, this spectacular victory on land was soured by the decisive victory that the Royal Navy attained at the Battle of Trafalgar on 21 October. After Trafalgar, Britain had total domination of the seas for the duration of the Napoleonic Wars. Question: By August 1805, Napoleon changed the primary target of his army's efforts from the English Channel to what area?

Answer: the Rhine

Question: Passage: As early as 1650, settlers from the Virginia colony moved into the area of Albemarle Sound. By 1663, King Charles II of England granted a charter to start a new colony on the North American continent; it generally established North Carolina's borders. He named it Carolina in honor of his father Charles I. By 1665, a second charter was issued to attempt to resolve territorial questions. In 1710, owing to disputes over governance, the Carolina colony began to split into North Carolina and South Carolina. The latter became a crown colony in 1729. Question: What year did King Charles II grant a charter to North America?

Answer: 1663

Question: Passage: While the Concordat restored much power to the papacy, the balance of church-state relations had tilted firmly in Napoleon's favour. He selected the bishops and supervised church finances. Napoleon and the pope both found the Concordat useful. Similar arrangements were made with the Church in territories controlled by Napoleon, especially Italy and Germany. Now, Napoleon could win favor with the Catholics while also controlling Rome in a political sense. Napoleon said in April 1801, "Skillful conquerors have not got entangled with priests. They can both contain them and use them." French children were issued a catechism that taught them to love and respect Napoleon. Question: Despite the Concordat, the balance of the relationship between the church and state had swung in whose favor?

Answer:
Napoleon's
