Information: - A skatepark, or skate park, is a purpose-built recreational environment made for skateboarding, BMX, scooter, wheelchair,and aggressive inline skating. A skatepark may contain half-pipes, quarter pipes, spine transfers, handrails, funboxes, vert ramps, pyramids, banked ramps, full pipes, pools, bowls, snake runs, stairsets, and any number of other objects. - A terrain park is an outdoor recreation area containing terrain that allows skiers, snowboarders and snowbikers to perform tricks. Terrain parks have their roots in skateparks and many of the features are common to both. - Snowboarding is a recreational activity and Olympic and Paralympic sport that involves descending a snow-covered slope while standing on a snowboard attached to a rider's feet. - Snowboards are boards that are usually the width of one's foot longways, with the ability to glide on snow. Snowboards are differentiated from monoskis by the stance of the user. In monoskiing, the user stands with feet inline with direction of travel (facing tip of monoski/downhill) (parallel to long axis of board), whereas in snowboarding, users stand with feet transverse (more or less) to the longitude of the board. Users of such equipment may be referred to as "snowboarder"s. "Commercial snowboards" generally require extra equipment such as bindings and special boots which help secure both feet of a snowboarder, who generally rides in an upright position. These types of boards are commonly used by people at ski hills or resorts for leisure, entertainment, and competitive purposes in the activity called snowboarding. - Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS). - Freestyle skiing is a skiing discipline comprising aerials, moguls, cross, half-pipe and slopestyle as part of the winter olympics. It can consist of a skier performing aerial flips and spins, and can include skiers sliding rails and boxes on their skis. It is also commonly referred to as freeskiing, jibbing, as well as many other names around the world. - Slopestyle is a winter sport in which athletes ski or snowboard down a course including a variety of obstacles including rails, jumps and other terrain park features. Points are scored for amplitude, originality and quality of tricks. The discipline has its roots in action sports like skateboarding and BMX and has very successfully crossed over into the snow sports worlds of skiing and snowboard. Twin-tip skis are used and are particularly useful if the skier lands backwards. Slopestyle tricks fall mainly into four categories: spins, grinds, grabs and flips. - Freeskiing , or new school skiing is a specific type of skiing , which involves tricks , jumps , and terrain park features , such as rails , boxes , jibs , or other obstacles . This form of skiing resulted from a combination of the growth in popularity of snowboarding as well as the progression of Freestyle skiing . '' Newschoolers '' , or those who specifically ski in this style , as opposed to traditional freestylers , freeriders , big mountain skiers , and racers , are often found in terrain parks , which are designed specifically for tricks . Whether freeskiing is a subset of Freestyle skiing or not is a matter of controversy . Some participants view it as a separate sport and do not refer to it as freestyle . The sport does not require participants to compete , but there are competitive events available at every level of the sport . Currently there are two Olympic freeskiing events , half - pipe skiing and slopestyle . These events make up two of the four Olympic freestyle skiing events . The sport has seen continual growth since its inception in the late 1990s . An entire industry has been created with this rapid popularization . As a result of this growth , there is currently a growing number of professional freeskiers . Most are highly competitive skiers , usually specializing in a certain freeskiing discipline . There are however professional skiers who do not compete , and rather produce and star in videos . After reading the paragraphs above, we are interested in knowing the entity with which 'freeskiing' exhibits the relationship of 'instance of'. Find the answer from the choices below. Choices: - action - activity - area - course - cross - entertainment - environment - equipment - federation - mode of transport - part - people - pipe - quality - recreation - scooter - skatepark - skiing - snow - snowboarding - stance - terrain - transport - travel - variety - winter sport
