Information: - Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting. - In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. - Terrain or relief (also topographical relief) is the vertical and horizontal dimension of the land surface. When relief is described underwater, the term bathymetry is used. The Latin Word "Terra (The root word of terrain)," is "Earth." - Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to maneuver, and energetic efficiency. Different animal species may use different gaits due to differences in anatomy that prevent use of certain gaits, or simply due to evolved innate preferences as a result of habitat differences. While various gaits are given specific names, the complexity of biological systems and interacting with the environment make these distinctions 'fuzzy' at best. Gaits are typically classified according to footfall patterns, but recent studies often prefer definitions based on mechanics. The term typically does not refer to limb-based propulsion through fluid mediums such as water or air, but rather to propulsion across a solid substrate by generating reactive forces against it (which can apply to walking while underwater as well as on land). - This article is about the mode of transportation . For other uses , see Walk ( disambiguation ) and Walking ( disambiguation ) . Walking ( also known as ambulation ) is one of the main gaits of locomotion among legged animals , and is typically slower than running and other gaits . Walking is defined by an ' inverted pendulum ' gait in which the body vaults over the stiff limb or limbs with each step . This applies regardless of the number of limbs - even arthropods , with six , eight or more limbs , walk . In the United Kingdom and Ireland , the term walking includes activities such as walking in a park and trekking in the Alps . However , in Canada and the United States the term for a long , vigorous walk is hiking , while the word walking covers shorter walks , especially in an urban setting . - Jogging is a form of trotting or running at a slow or leisurely pace. The main intention is to increase physical fitness with less stress on the body than from faster running, or to maintain a steady speed for longer periods of time. Performed over long distances, it is a form of aerobic endurance training. - Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is inherently tied to embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated over immediate (embryology) and long (evolution) timescales. Human anatomy is one of the basic essential sciences of medicine. - Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial environments. Locomotion on land raises different problems than that in water, with reduced friction being replaced by the effects of gravity. Given the paragraphs above, decide what entity has the relation 'subclass of' with 'terrestrial locomotion'.

Answer: walking

Information: - Aether is a video game designed by Edmund McMillen and Tyler Glaiel and published by Armor Games , released on September 3 , 2008 . Players control a lonely boy and an octopus - like monster that the boy encounters , solving puzzles on different planets to restore them from monochrome to color . The pair travel through space by swinging on clouds and asteroids with the monster 's elongated tongue , searching other planets for life to which the boy can relate . It is also a part of The Basement Collection . McMillen and Glaiel created the game and developed it in 14 days . Both developers expressed interest in seeing a version being released on the Wii game console through the WiiWare online service . Aether received a positive response from video game blogs for its unusual visual style and atmosphere . The single looped piece of background music received a mixed response and the controls were highlighted as an area of the game that could have been improved before release . - A website is a collection of related web pages, including multimedia content, typically identified with a common domain name, and published on at least one web server. A website may be accessible via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by referencing a uniform resource locator (URL) that identifies the site. - A browser game is a computer game that is played over the Internet using a web browser. Browser games can be run using standard web technologies or browser plug-ins. The creation of such games usually involves use of standard web technologies as a frontend and other technologies to provide a backend. Browser games include all video game genres and can be single-player or multiplayer. Browser games are also portable and can be played on multiple different devices, web browsers, and operating systems. Browser games come in many genres and themes that appeal to both regular and casual players. - Founded in 2004 by Daniel McNeely, Armor Games is a website based in Irvine, California, that hosts free Flash-based browser games across a wide variety of genres, including point-and-click adventure, arcade, puzzle, and even MMOs such as The Last Stand - Dead Zone. In addition to sponsoring certain browser games, Armor Games has begun acting as a publisher for other titles such as Soda Dungeon, GemCraft - Chasing Shadows, and Super Chibi Knight, as well as others like the upcoming indie hardcore platformer, Never Give Up. The company has released games for iOS and Android mobile devices and Steam, and others slated to launch on PlayStation 4 and Xbox One. - In photography and computing, a grayscale or greyscale digital image is an image in which the value of each pixel is a single sample, that is, it carries only intensity information. Images of this sort, also known as black-and-white, are composed exclusively of shades of gray, varying from black at the weakest intensity to white at the strongest. - Monochrome describes paintings, drawings, design, or photographs in one color or values of one color. A monochromatic object or image reflects colors in shades of limited colors or hues. Images using only shades of grey (with or without black or white) are called grayscale or black-and-white. However, scientifically speaking, monochromatic light refers to visible light of a narrow band of wavelengths (see spectral color). Given the paragraphs above, decide what entity has the relation 'distribution' with 'browser game'.
