user: Problem: Please answer a question about the following article about Middle Ages:
In the 13th century mendicant orders—the Franciscans and the Dominicans—who swore vows of poverty and earned their living by begging, were approved by the papacy. Religious groups such as the Waldensians and the Humiliati also attempted to return to the life of early Christianity in the middle 12th and early 13th centuries, but they were condemned as heretical by the papacy. Others joined the Cathars, another heretical movement condemned by the papacy. In 1209, a crusade was preached against the Cathars, the Albigensian Crusade, which in combination with the medieval Inquisition, eliminated them.
What notable vow was sworn by the mendicant orders?
A: poverty
Problem: Please answer a question about the following article about Annelid:
It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia. The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).
What do annelid eggs become?
A: trochophore larvae
Problem: Please answer a question about the following article about British Empire:
The Napoleonic Wars were therefore ones in which Britain invested large amounts of capital and resources to win. French ports were blockaded by the Royal Navy, which won a decisive victory over a Franco-Spanish fleet at Trafalgar in 1805. Overseas colonies were attacked and occupied, including those of the Netherlands, which was annexed by Napoleon in 1810. France was finally defeated by a coalition of European armies in 1815. Britain was again the beneficiary of peace treaties: France ceded the Ionian Islands, Malta (which it had occupied in 1797 and 1798 respectively), Mauritius, St Lucia, and Tobago; Spain ceded Trinidad; the Netherlands Guyana, and the Cape Colony. Britain returned Guadeloupe, Martinique, French Guiana, and Réunion to France, and Java and Suriname to the Netherlands, while gaining control of Ceylon (1795–1815).
When was Napoleon finally defeated?
A: 1815
Problem: Please answer a question about the following article about Marshall Islands:
The European powers recognized the islands as part of the Spanish East Indies in 1874. However, Spain sold the islands to the German Empire in 1884, and they became part of German New Guinea in 1885. In World War I the Empire of Japan occupied the Marshall Islands, which in 1919 the League of Nations combined with other former German territories to form the South Pacific Mandate. In World War II, the United States conquered the islands in the Gilbert and Marshall Islands campaign. Along with other Pacific Islands, the Marshall Islands were then consolidated into the Trust Territory of the Pacific Islands governed by the US. Self-government was achieved in 1979, and full sovereignty in 1986, under a Compact of Free Association with the United States. Marshall Islands has been a United Nations member state since 1991.
In what year did the Marshall Islands gain official recognition by the major European nations?
A:

assistant: 1874
