Here is a question about this article: Traditionally the annelids have been divided into two major groups, the polychaetes and clitellates. In turn the clitellates were divided into oligochaetes, which include earthworms, and hirudinomorphs, whose best-known members are leeches. For many years there was no clear arrangement of the approximately 80 polychaete families into higher-level groups. In 1997 Greg Rouse and Kristian Fauchald attempted a "first heuristic step in terms of bringing polychaete systematics to an acceptable level of rigour", based on anatomical structures, and divided polychaetes into:
What is the answer to this question: What two groups are annelids traditionally divided among?

So... polychaetes and clitellates


Here is a question about this article: More radical reformists were increasingly convinced that a rapid transition to a market economy was required, even if the eventual outcome meant the disintegration of the Soviet Union into several independent states. Independence also accorded with Yeltsin's desires as president of the Russian Federation, as well as those of regional and local authorities to get rid of Moscow’s pervasive control. In contrast to the reformers' lukewarm response to the treaty, the conservatives, "patriots," and Russian nationalists of the USSR – still strong within the CPSU and the military – were opposed to weakening the Soviet state and its centralized power structure.
What is the answer to this question: What was Yeltsin president of?

So... the Russian Federation,


Here is a question about this article: According to Joshua Baron – a "researcher, lecturer, and consultant on international conflict" – since the early 1960s direct military conflicts and major confrontations have "receded into the background" with regards to relations among the great powers. Baron argues several reasons why this is the case, citing the unprecedented rise of the United States and its predominant position as the key reason. Baron highlights that since World War Two no other great power has been able to achieve parity or near parity with the United States, with the exception of the Soviet Union for a brief time. This position is unique among the great powers since the start of the modern era (the 16th century), where there has traditionally always been "tremendous parity among the great powers". This unique period of American primacy has been an important factor in maintaining a condition of peace between the great powers.
What is the answer to this question: Who's primacy has factored into maintaining peace among powers?

So...
