In 2007 Torsten Struck and colleagues compared 3 genes in 81 taxa, of which 9 were outgroups, in other words not considered closely related to annelids but included to give an indication of where the organisms under study are placed on the larger tree of life. For a cross-check the study used an analysis of 11 genes (including the original 3) in 10 taxa. This analysis agreed that clitellates, pogonophorans and echiurans were on various branches of the polychaete family tree. It also concluded that the classification of polychaetes into Scolecida, Canalipalpata and Aciculata was useless, as the members of these alleged groups were scattered all over the family tree derived from comparing the 81 taxa. In addition, it also placed sipunculans, generally regarded at the time as a separate phylum, on another branch of the polychaete tree, and concluded that leeches were a sub-group of oligochaetes rather than their sister-group among the clitellates. Rouse accepted the analyses based on molecular phylogenetics, and their main conclusions are now the scientific consensus, although the details of the annelid family tree remain uncertain.
What did Rouse decide leeches were a supergroup of?
A: unanswerable

Parque Batlle (formerly: Parque de los Aliados, translation: "Park of the Allies") is a major public central park, located south of Avenida Italia and north of Avenue Rivera. Along with Parque Prado and Parque Rodo it is one of three large parks that dominate Montevideo. The park and surrounding area constitute one of the 62 neighbourhoods (barrios) of the city. The barrio of Parque Batlle is one of seven coastal barrios, the others being Buceo, Carrasco, Malvin, Pocitos, Punta Carretas, and Punta Gorda. The current barrio of Parque Battle includes four former districts: Belgrano, Italiano, Villa Dolores and Batlle Park itself and borders the neighbourhoods of La Blanqueada, Tres Cruces, Pocitos and Buceo. It has a high population density and most of its households are of medium-high- or high-income. Villa Dolores, a subdistrict of Parque Batlle, took its name from the original villa of Don Alejo Rossell y Rius and of Dona Dolores Pereira de Rossel. On their grounds, they started a private collection of animals that became a zoological garden and was passed to the city in 1919; in 1955 the Planetarium of Montevideo was built within its premises.
What major public central park is located south of Avenida Italia?
A: Parque Batlle

The 19th-century Liberal Prime Minister William Ewart Gladstone considered Burke "a magazine of wisdom on Ireland and America" and in his diary recorded: "Made many extracts from Burkesometimes almost divine". The Radical MP and anti-Corn Law activist Richard Cobden often praised Burke's Thoughts and Details on Scarcity. The Liberal historian Lord Acton considered Burke one of the three greatest Liberals, along with William Gladstone and Thomas Babington Macaulay. Lord Macaulay recorded in his diary: "I have now finished reading again most of Burke's works. Admirable! The greatest man since Milton". The Gladstonian Liberal MP John Morley published two books on Burke (including a biography) and was influenced by Burke, including his views on prejudice. The Cobdenite Radical Francis Hirst thought Burke deserved "a place among English libertarians, even though of all lovers of liberty and of all reformers he was the most conservative, the least abstract, always anxious to preserve and renovate rather than to innovate. In politics he resembled the modern architect who would restore an old house instead of pulling it down to construct a new one on the site". Burke's Reflections on the Revolution in France was controversial at the time of its publication, but after his death, it was to become his best known and most influential work, and a manifesto for Conservative thinking.
What architect admired Burke?

In a nationally televised speech early in the morning of December 25, 1991, Gorbachev resigned as president of the USSR or, as he put it, "I hereby discontinue my activities at the post of President of the Union of Soviet Socialist Republics." He declared the office extinct, and all of its powers (such as control of the nuclear arsenal) were ceded to Yeltsin. A week earlier, Gorbachev had met with Yeltsin and accepted the fait accompli of the Soviet Union's dissolution. On the same day, the Supreme Soviet of the Russian SFSR adopted a statute to change Russia's legal name from "Russian Soviet Federative Socialist Republic" to "Russian Federation," showing that it was now a sovereign state.
When did Gorbachev resign?
A:
December 25, 1991
