Context: Sidney K. "Sid" Meier (born February 24, 1954) is a programmer, designer, and producer of several popular strategy video games and simulation video games, most notably the "Civilization" series. Meier co-founded MicroProse in 1982 with Bill Stealey and is the Director of Creative Development of Firaxis Games, which he co-founded with Jeff Briggs and Brian Reynolds in 1996. He has won several prestigious accolades for his contributions to the video game industry., The Commodore 64, also known as the C64, C-64, C= 64, or occasionally CBM 64 or VIC-64 in Sweden, is an 8-bit home computer introduced in January 1982 by Commodore International. It is listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its of RAM. It had superior sound and graphical specifications compared to other earlier systems such as the Apple II and Atari 800, with multi-color sprites and a more advanced sound processor., A video game publisher is a company that publishes video games that they have either developed internally or have had developed by a video game developer. As with book publishers or publishers of DVD movies, video game publishers are responsible for their product's manufacturing and marketing, including market research and all aspects of advertising., Airborne Ranger is a video game developed and released by MicroProse in 1987 for the Amstrad CPC, Commodore 64, ZX Spectrum, and MS-DOS. It is an action game in which a sole U.S. Army Ranger is sent to infiltrate the enemy territory to complete various objectives. Amiga and Atari ST versions were released few years later and were a wholly independent development effort and different from gameplay standpoint., The action game is a video game genre that emphasizes physical challenges, including handeye coordination and reaction-time. The genre includes diverse subgenres such as fighting games, shooter games and platform games which are widely considered the most important action games, though some real-time strategy games are also considered to be action games., X-COM (sometimes stylized as "X-Com") is a science fiction video game franchise featuring an elite international organization tasked with countering alien invasions of Earth. The series began with the strategy video game "" created by Mythos Games and MicroProse in 1994. The original line up by MicroProse included six published and at least two cancelled games, as well as two novels. The "X-COM" series, in particular its original entry, achieved a sizable cult following and has influenced many other video games; including the creation of a number of clones, spiritual successors, and unofficial remakes., The ZX Spectrum is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd. It was manufactured in Dundee, Scotland, in the now closed Timex factory., Special Forces is a video game released in 1991 by MicroProse . In the game , a team of special operatives are to infiltrate enemy territory to complete various objectives . The game is a sequel to Airborne Ranger ., The Amiga is a family of personal computers sold by Commodore in the 1980s and 1990s. Based on the Motorola 68000 family of microprocessors, the machine has a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS. The Amiga provided a significant upgrade from earlier 8-bit home computers, including Commodore's own C64., A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial., MS-DOS (; acronym for "Microsoft Disk Operating System") is a discontinued operating system for x86-based personal computers mostly developed by Microsoft. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system by Microsoft Corporation., MicroProse was an American video game publisher and developer founded by "Wild" Bill Stealey and Sid Meier in 1982 as MicroProse Software Inc. It developed and published numerous games, many of which are regarded as groundbreaking, classics and cult titles, including starting the "Civilization" and "X-COM" series. Most of their internally developed titles were vehicle simulation and strategy games., The Atari ST is a line of home computers from Atari Corporation and the successor to the Atari 8-bit family. The initial ST model, the 520ST, saw limited release in the spring of 1985 and was widely available in July. The Atari ST is the first personal computer to come with a bit-mapped color GUI, using a version of Digital Research's GEM released in February 1985. The 1040ST, released in 1986, is the first personal computer to ship with a megabyte of RAM in the base configuration and also the first with a cost-per-kilobyte of less than US$1., Subject: special forces , Relation: genre, Options: (A) action game (B) advertising (C) animal (D) book (E) cult (F) family (G) graphics (H) marketing (I) research (J) science (K) strategy video game (L) various (M) video

Context: Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound.", Aerobic gymnastics or sport aerobics is a competitive sport originating from traditional aerobics in which complex, high-intensity movement patterns and elements of varying difficulty are performed to music. In addition to aerobics, it combines elements of acrobatic gymnastics, rhythmic gymnastics and often artistic gymnastics along with music, dance and choreography., Rhythmic gymnastics is a sport in which individuals or groups of five or more manipulate one or two pieces of apparatus: rope, hoop, ball, clubs, ribbon and freehand (no apparatus). Rhythmic gymnastics is a sport that combines elements of ballet, gymnastics, dance, and apparatus manipulation. The victor is the participant who earns the most points, determined by a panel of judges, for leaps, balances, pirouettes (pivots), apparatus handling, and execution. The choreography must cover the entire floor and contain a balance of jumps, leaps, pivots, balances (there is a certain number depending on which level you are) and flexibility movements. Each movement involves a high degree of athletic skill. Physical abilities needed by a rhythmic gymnast include strength, power, flexibility, agility, dexterity, endurance and hand-eye coordination., Artistic gymnastics is a discipline of gymnastics in which athletes perform short routines (ranging from approximately 30 to 90 seconds) on different apparatus, with less time for vaulting. The sport is governed by the Fédération Internationale de Gymnastique (FIG), which designs the Code of Points and regulates all aspects of international elite competition. Within individual countries, gymnastics is regulated by national federations, such as British Gymnastics in the United Kingdom and USA Gymnastics in the United States. Artistic gymnastics is a popular spectator sport at the Summer Olympic Games and in other competitive environments., Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness (flexibility, muscular strength, and cardio-vascular fitness). It is usually performed to music and may be practiced in a group setting led by an instructor (fitness professional), although it can be done solo and without musical accompaniment. With the goal of preventing illness and promoting physical fitness, practitioners perform various routines comprising a number of different dance-like exercises. Formal aerobics classes are divided into different levels of intensity and complexity. A well-balanced aerobics class will have five components: warm-up (5-10 minutes), cardio vascular conditioning (25-30 minutes), muscular strength and conditioning (10-15 minutes), cool-down (5-8 minutes) and stretching and flexibility (5-8 minutes). Aerobics classes may allow participants to select their level of participation according to their fitness level. Many gyms offer a variety of aerobic classes. Each class is designed for a certain level of experience and taught by a certified instructor with a specialty area related to their particular class., Choreography is the art or practice of designing sequences of movements of physical bodies (or their depictions) in which motion, form, or both are specified. "Choreography" may also refer to the design itself. A choreographer is one who creates choreographies by practicing the art of choreography, a process known as "choreographing". Choreography is used in a variety of fields, including musical theater, cheerleading, cinematography, gymnastics, fashion shows, ice skating, marching band, show choir, theatre, synchronized swimming, cardistry, video game production and animated art. In the performing arts, choreography applies to human movement and form. In dance, choreography is also known as dance choreography or "dance composition"., 9th Aerobic Gymnastics World Championships were held in Nanjing , China from June 1 to June 3 , 2006 ., Acrobatic gymnastics (previously called sport acrobatics) is a competitive gymnastic discipline where partnerships of gymnasts work together and perform figures consisting of acrobatic moves, dance and tumbling, set to music. There are three types of routines; a 'balance' routine where the focus is on strength, poise and flexibility; a 'dynamic' routine which includes throws, somersaults and catches, and (at FIG level 6 and above) a 'combined' routine which includes elements from both balance and dynamic., Subject: 2006 aerobic gymnastics world championships, Relation: sport, Options: (A) artistic gymnastics (B) cheerleading (C) gymnastics (D) ice skating (E) music (F) rhythmic gymnastics (G) sport (H) sport aerobics (I) synchronized swimming

Context: Sinistral and dextral , in some scientific fields , are the two types of chirality ( `` handedness '' ) or relative direction . The terms are derived from the Latin words for `` left '' ( sinister ) and `` right '' ( dexter ) . Other disciplines have different terms ( such as dextro - and laevo - rotary , in chemistry , or clockwise and anticlockwise in physics ) or simply use left and right ( as in anatomy ) . Relative direction and chirality are distinct concepts . Relative direction is from the point of view of the observer . A completely symmetrical object has a left and a right side , from the observer 's point of view , if the top and bottom and direction of observation are defined . Chirality , however , is observer - independent : no matter how one looks at a right - hand screw thread , it remains different from a left - hand screw thread . Therefore , a symmetrical object has sinistral and dextral directions arbitrarily defined by the position of the observer , while an object that has chirality can have sinistral and dextral directions defined by characteristics of the object , no matter the position of the observer ., Handedness is a better (faster or more precise) performance or individual preference for use of a hand, known as the dominant hand. Handedness is not a discrete variable (right or left), but a continuous one that can be expressed at levels between strong left and strong right., In classical physics and special relativity, an inertial frame of reference (also inertial reference frame or inertial frame, Galilean reference frame or inertial space) is a frame of reference that describes time and space homogeneously, isotropically, and in a time-independent manner. The physics of a system in an inertial frame have no causes external to the system., Physics (from , from "phúsis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves., The most common relative directions are left, right, forward(s), backward(s), up, and down. No absolute direction corresponds to any of the relative directions. This is a consequence of the translational invariance of the laws of physics: nature, loosely speaking, behaves the same no matter what direction one moves. As demonstrated by the Michelson-Morley null result, there is no absolute inertial frame of reference. There are definite relationships between the relative directions, however. Left and right, forward and backward, and up and down are three pairs of complementary directions, each pair orthogonal to both of the others. Relative directions are also known as egocentric coordinates., Subject: sinistral and dextral, Relation: instance_of, Options: (A) behavior (B) direction (C) energy (D) force (E) frame of reference (F) motion (G) null (H) performance (I) physics (J) result (K) space (L) three (M) variable
