Problem: The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-groups of polychaetes. Annelids are considered members of the Lophotrochozoa, a "super-phylum" of protostomes that also includes molluscs, brachiopods, flatworms and nemerteans.
What do annelids use to move?
The answer is the following: parapodia

Problem: With Zaifeng gone, Yuan Shikai and his Beiyang commanders effectively dominated Qing politics. He reasoned that going to war would be unreasonable and costly, especially when noting that the Qing government had a goal for constitutional monarchy. Similarly, Sun Yat-sen's government wanted a republican constitutional reform, both aiming for the benefit of China's economy and populace. With permission from Empress Dowager Longyu, Yuan Shikai began negotiating with Sun Yat-sen, who decided that his goal had been achieved in forming a republic, and that therefore he could allow Yuan to step into the position of President of the Republic of China.
Who led the Qing?
The answer is the following: Yuan Shikai

Problem: The Germans expected to negotiate an end to the war but immediately ordered an advance on Paris; by 15 September Moltke issued the orders for an investment of Paris and on 20 September the encirclement was complete. Bismarck met Favre on 18 September at the Château de Ferrières and demanded a frontier immune to a French war of revenge, which included Strasbourg, Alsace and most the Moselle department in Lorraine of which Metz was the capital. In return for an armistice for the French to elect a National Assembly, Bismarck demanded the surrender of Strasbourg and the fortress city of Toul. To allow supplies into Paris, one of the perimeter forts had to be handed over. Favre was unaware that the real aim of Bismarck in making such extortionate demands was to establish a durable peace on the new western frontier of Germany, preferably by a peace with a friendly government, on terms acceptable to French public opinion. An impregnable military frontier was an inferior alternative to him, favoured only by the militant nationalists on the German side.
Bismarck and Favre met on what date?
The answer is the following: 18 September

Problem: New York City has focused on reducing its environmental impact and carbon footprint. Mass transit use in New York City is the highest in the United States. Also, by 2010, the city had 3,715 hybrid taxis and other clean diesel vehicles, representing around 28% of New York's taxi fleet in service, the most of any city in North America.
What percentage of the New York City cab fleet was clean diesel or hybrid in 2010?
The answer is the following:
28%
