Problem: Please answer a question about the following article about Paris:
Aside from the 20th century addition of the Bois de Boulogne, Bois de Vincennes and Paris heliport, Paris' administrative limits have remained unchanged since 1860. The Seine département had been governing Paris and its suburbs since its creation in 1790, but the rising suburban population had made it difficult to govern as a unique entity. This problem was 'resolved' when its parent "District de la région parisienne" (Paris region) was reorganised into several new departments from 1968: Paris became a department in itself, and the administration of its suburbs was divided between the three departments surrounding it. The Paris region was renamed "Île-de-France" in 1977, but the "Paris region" name is still commonly used today. Paris was reunited with its suburbs on January 1, 2016 when the Métropole du Grand Paris came into existence.
WHen was District de la region parisienne reorganised?
A: 1968
Problem: Please answer a question about the following article about Dominican Order:
The Dominican Order came into being in the Middle Ages at a time when religion began to be contemplated in a new way. Men of God were no longer expected to stay behind the walls of a cloister. Instead, they travelled among the people, taking as their examples the apostles of the primitive Church. Out of this ideal emerged two orders of mendicant friars: one, the Friars Minor, was led by Francis of Assisi; the other, the Friars Preachers, by Dominic of Guzman. Like his contemporary, Francis, Dominic saw the need for a new type of organization, and the quick growth of the Dominicans and Franciscans during their first century of existence confirms that the orders of mendicant friars met a need.
How many orders of mendicant friars came out of the Middle Ages?
A: two
