Problem: In the late 13th and early 14th centuries, a process took place primarily in Italy but partly also in the Empire that historians have termed a 'commercial revolution'. Among the innovations of the period were new forms of partnership and the issuing of insurance, both of which contributed to reducing the risk of commercial ventures; the bill of exchange and other forms of credit that circumvented the canonical laws for gentiles against usury, and eliminated the dangers of carrying bullion; and new forms of accounting, in particular double-entry bookkeeping, which allowed for better oversight and accuracy.
Laws against what lending practice were addressed by the creation of bills of exchange?
The answer is the following: usury

Problem: From Elizabeth's birth onwards, the British Empire continued its transformation into the Commonwealth of Nations. By the time of her accession in 1952, her role as head of multiple independent states was already established. In 1953, the Queen and her husband embarked on a seven-month round-the-world tour, visiting 13 countries and covering more than 40,000 miles by land, sea and air. She became the first reigning monarch of Australia and New Zealand to visit those nations. During the tour, crowds were immense; three-quarters of the population of Australia were estimated to have seen her. Throughout her reign, the Queen has made hundreds of state visits to other countries and tours of the Commonwealth; she is the most widely travelled head of state.
How many nations did Elizabeth visit on tour in 1953?
The answer is the following: 13 countries

Problem: Dumbwaiters are small freight elevators that are intended to carry food, books or other small freight loads rather than passengers. They often connect kitchens to rooms on other floors. they usually do not have the same safety features found in passenger elevators, like various ropes for redundancy. they have a lower capacity, and they can be up to 1 meter (3 ft.) tall. there's a control panel at every stop, that mimics the ones found in passenger elevators, like calling, door control, floor selection.
What are small freight elevators used for things such as food, called?
The answer is the following: Dumbwaiters

Problem: Protestantism also spread from the German lands into France, where the Protestants were nicknamed Huguenots. Calvin continued to take an interest in the French religious affairs from his base in Geneva. He regularly trained pastors to lead congregations there. Despite heavy persecution, the Reformed tradition made steady progress across large sections of the nation, appealing to people alienated by the obduracy and the complacency of the Catholic establishment. French Protestantism came to acquire a distinctly political character, made all the more obvious by the conversions of nobles during the 1550s. This established the preconditions for a series of conflicts, known as the French Wars of Religion. The civil wars gained impetus with the sudden death of Henry II of France in 1559. Atrocity and outrage became the defining characteristics of the time, illustrated at their most intense in the St. Bartholomew's Day massacre of August 1572, when the Roman Catholic party annihilated between 30,000 and 100,000 Huguenots across France. The wars only concluded when Henry IV of France issued the Edict of Nantes, promising official toleration of the Protestant minority, but under highly restricted conditions. Roman Catholicism remained the official state religion, and the fortunes of French Protestants gradually declined over the next century, culminating in Louis XIV's Edict of Fontainebleau which revoked the Edict of Nantes and made Roman Catholicism the sole legal religion once again. In response to the Edict of Fontainebleau, Frederick William I, Elector of Brandenburg declared the Edict of Potsdam, giving free passage to Huguenot refugees. In the late 17th century many Huguenots fled to England, the Netherlands, Prussia, Switzerland, and the English and Dutch overseas colonies. A significant community in France remained in the Cevennes region.
Whose death caused an increase in the French civil wars?
The answer is the following:
Henry II
