Q: Information:  - Kievan Rus' (, ) was a loose federation of East Slavic tribes in Europe from the late 9th to the mid-13th century, under the reign of the Rurik dynasty. The modern peoples of Belarus, Ukraine, and Russia all claim Kievan Rus' as their cultural ancestors.  - Rurik or Riurik (from "Rørik"; 830  879) was a legendary Varangian chieftain who gained control of Ladoga in 862, built the Holmgard settlement near Novgorod, and founded the Rurik Dynasty, which ruled Kievan Rus (and later the Grand Duchy of Moscow and Tsardom of Russia) until the 17th century.  - For the cruiser see Russian cruiser Vladimir Monomakh , for the submarine see Russian submarine Vladimir Monomakh Vladimir II Monomakh ( Old East Slavic :   , Volodimer Monomakh ; Christian name : Vasiliy , or Basileios ) ( 1053 -- 19 May 1125 ) reigned as Velikiy Kniaz ( Grand Prince ) of Kievan Rus ' from 1113 to 1125 .  - The Rurik dynasty or Rurikids was a dynasty founded by the Varangian prince Rurik, who established himself in Novgorod around the year AD 862. The Rurikids were the ruling dynasty of Kievan Rus' (after 862), as well as the successor principalities of Galicia-Volhynia (after 1199), Chernigov, Vladimir-Suzdal, and the Grand Duchy of Moscow, and the founders of the Tsardom of Russia. They ruled until 1598 and the Time of Troubles, following which they were succeeded by the Romanovs. They are one of Europe's oldest royal houses, with numerous existing cadet branches.    'vladimir ii monomakh' is related to which object entity through the relation of 'noble family'?  Choices: - rurik  - rurik dynasty
A: rurik dynasty


Q: Information:  - Reticulum is a small, faint constellation in the southern sky. Its name is Latin for a small net, or reticlea net of crosshairs at the focus of a telescope eyepiece that is used to measure star positions. The constellation is best viewed between October and December, but cannot be seen from middle to northern latitudes.  - SN 2005df was a Type Ia supernova in galaxy NGC 1559 . It was discovered in Australia by Robert Evans on the early morning of August 5 , 2005 with a 13.8 magnitude , about ten days before reaching its maximum brightness of 12.3 . SN 2005df was the 104th supernova discovered in 2005 .  - Sagittarius A* (pronounced "Sagittarius A-star", standard abbreviation Sgr A*) is a bright and very compact astronomical radio source at the center of the Milky Way, near the border of the constellations Sagittarius and Scorpius. It is part of a larger astronomical feature known as Sagittarius A. Sagittarius A* is thought to be the location of a supermassive black hole, like those that are now generally accepted to be at the centers of most spiral and elliptical galaxies. Observations of the star S2 in orbit around Sagittarius A* have been used to show the presence of, and produce data about, the Milky Way's central supermassive black hole, and have led to the conclusion that Sagittarius A* is the site of that black hole.  - A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek "", literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few billion stars to giants with one hundred trillion stars, each orbiting its galaxy's center of mass. Galaxies are categorized according to their visual morphology as elliptical, spiral and irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of March 2016, GN-z11 is the oldest and most distant observed galaxy with a comoving distance of 32 billion light-years from Earth, and observed as it existed just 400 million years after the Big Bang.  - NGC 1559 is a barred spiral galaxy in the constellation Reticulum. It is also a Seyfert galaxy. Although it was originally thought to be a member of the Dorado Group, subsequent observations have shown that it is in fact not a member of any galaxy group or cluster and does not have any nearby companions. NGC 1559 has massive spiral arms and strong star formation. It contains a small bar which is oriented nearly east-west and spans 40. Its bar and disc are the source of very strong radio emissions.  - The Dorado Group is a loose concentration of galaxies containing both spirals and ellipticals. It is generally considered a 'galaxy group' but may approach the size of a 'galaxy cluster'. It lies primarily in the southern constellation Dorado and is one of the richest galaxy groups of the Southern Hemisphere. Gérard de Vaucouleurs was the first to identify it in 1975 as a large complex nebulae II in the Dorado region, designating it as G16.    'sn 2005df' is related to which object entity through the relation of 'constellation'?  Choices: - dorado  - reticulum  - sagittarius
A: reticulum
