Question: Marina Lebedeva participates in a winter sport that combines cross-country skiing and rifle shooting. What is the sport called?
Context: Military patrol was a team winter sport in which athletes competed in cross-country skiing, ski mountaineering and rifle shooting.  It was usually contested between countries or military units. The Worldloppet Ski Federation is a federation of long distance cross-country skiing events whose aim is to promote cross-country skiing through various ski races.  The federation was founded in 1978 in Uppsala, Sweden.  The aim of Worldloppet is to promote the sport of cross-country skiing through the various ski races around the world. The biathlon is a winter sport that combines cross-country skiing and rifle shooting. The summer biathlon is a sporting event that combines running and rifle shooting.  It is modeled after the biathlon, which is an Olympic sport that integrates rifle shooting with cross-country skiing.  The Summer Biathlon World Championships have been held annually since 1996. Marina Lebedeva (born in Aqkol on (1985--) 29, 1985 ) is a Kazakh biathlete. Biathlon refers to the winter sport that combines cross-country skiing and rifle shooting. Cross-country skiing is a form of skiing where skiers rely on their own locomotion to move across snow-covered terrain, rather than using ski lifts or other forms of assistance.  Cross-country skiing is widely practiced as a sport and recreational activity; however, some still use it as a means of transportation.  Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport. The sport of cross-country skiing encompasses a variety of formats for cross-country skiing races over courses of varying lengths according to rules sanctioned by the International Ski Federation and by various national organizations, such as the U.S. Ski and Snowboard Association (USSA) and Cross Country Ski Canada.  International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games.  Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing.  It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation.  Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment. Milanko Petrović () (born September 21, 1988 in Sjenica) is a Serbian biathlete who participated at the 2010 Winter Olympics, becoming the first olympic biathlete for independent Serbia.  At the 2014 Winter Olympics he carried Serbian flag at the opening ceremony and competed in biathlon and cross-country skiing.  He represents Serbia at the Biathlon World Championships and he is a regular participant of the Biathlon World Cup and the first ever Serb to win World Cup points.  Occasionally, he competes in cross-country skiing.  At the 2013 Winter Universiade he made a remarkable success by winning first ever international medals for Serbia in biathlon and cross-country skiing. Freestyle skiing is one of the six skiing disciplines contested at the Winter Olympic Games, and one of the youngest.  In 1924, the first Winter Olympics featured Nordic skiing disciplines (cross-country skiing, ski jumping, and Nordic combined), while alpine skiing was first contested in 1936.  Only at the 1992 Winter Olympics, in Albertville, France, were freestyle skiing events first held as official medal events.  Before that, freestyle skiing was contested at the 1988 Winter Olympics as a demonstration sport, consisting of events for both men and women in three variants: moguls, aerials and ski ballet.  In Albertville, moguls was the first-ever official freestyle skiing medal event; aerials and ski ballet were also held but still as demonstration events.  The growing popularity of aerials convinced the International Olympic Committee (IOC) to add this freestyle discipline to the 1994 Winter Olympics official program.  Moguls and aerials have thus been contested at every Winter Games since.  Ski cross inclusion in the Winter Olympics program was approved at an IOC Executive Board meeting in November 2006, and the first events were held at the 2010 Winter Olympics.
