Ques:Information: - A lineal descendant, in legal usage, is a blood relative in the direct line of descent - the children, grandchildren, great-grandchildren, etc. of a person. In a legal procedure sense, lineal descent refers to the acquisition of estate by inheritance from grandparent to parent and parent to child, whereas collateral descent refers to the acquisition of estate or real property by inheritance from sibling to sibling, and cousin to cousin. - A clade (from , "klados", "branch") is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life". - Reptiles are tetrapod (four-limbed vertebrate) animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. - Sauropsida ( '' lizard faces '' ) is a group of amniotes that includes all existing reptiles and birds as well as their fossil ancestors and relatives . Sauropsida is distinguished from Synapsida , which includes mammals and their fossil ancestors . This clade includes Parareptilia and other extinct clades . All living sauropsids are members of the sub-group Diapsida . - The superclass Tetrapoda (Ancient Greek s tetrapods, "four-footed"), or the tetrapods , comprises the first four-limbed vertebrates and their descendants, including the living and extinct amphibians, birds, mammals, reptiles and some ancient, exclusively aquatic creatures such as the Acanthostega. Tetrapods evolved from the lobe-finned fishes around 390 million years ago in the middle Devonian Period, with modern tetrapod groups having appeared by the late Devonian, 367.5 million years ago. The specific aquatic ancestors of the tetrapods, and the process by which land colonization occurred, remain unclear, and are areas of active research and debate among palaeontologists at present. - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs. - Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists. - Parareptilia ("at the side of reptiles") is a subclass or clade of reptiles which is variously defined as an extinct group of primitive anapsids, or a more cladistically correct alternative to Anapsida. Whether the term is valid depends on the phylogenetic position of turtles, the relationships of which to other reptilian groups are still uncertain. Given the information above, choose from the list below the object entity that exhibits the relation 'subclass of' with the subject 'sauropsida'. Choices: - animal - biology - branch - cretaceous - family - formicidae - group - growth - hymenoptera - inheritance - insects - life - line - lineal descendant - node - person - position - scale - sense - single - species - subclass - term - tetrapoda - tree

Ques:Information: - PKP Group (pl: "Grupa PKP") is a Polish conglomerate founded in 2001 from the former single national rail operator, Polskie Koleje Pastwowe. The purpose of this change was to match European Union directives of dividing transport service from rail system management and founding separate companies able to sell their service outside the rail business. - EW90 is the name for German Reichsbahn ET 165 electric multiple units working for Polish State Railways ( PKP ) after World War II. - An electric multiple unit or EMU is a multiple unit train consisting of self-propelled carriages, using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. Most EMUs are used for passenger trains, but some have been built or converted for specialised non-passenger roles, such as carrying mail or luggage, or in departmental use, for example as de-icing trains. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. - The company was founded when the former "" state-owned operator was divided into several units based on the requirements laid down by the European Union. PKP SA is the dominant company in PKP Group collective that resulted from the split, and maintains in 100% share control, being fully responsible for management of all of the other PKP Group component companies. The group's organisations are dependent upon PKP SA, but proposals for privatisation have been made. Given the information above, choose from the list below the object entity that exhibits the relation 'subclass of' with the subject 'pkp class ew90'. Choices: - area - capital - collective - company - currency - force - group - home - locomotive - management - member - passport - rail - service - single - state - trade - transport
