Answer: nurzhan smanov , boxing
input: Please answer the following: Information: - The Nordic combined events have been contested at the Winter Olympic Games since 1924. The first competition involved 18km cross-country skiing, followed by ski jumping. Whoever earned the most points from both competitions won the event. At the 1952 Winter Olympics, the ski jumping was held first, followed by 18km cross-country skiing. The cross-country skiing portion was reduced to 15km at the 1956 Winter Olympics. The ski jumping styles would change over the years as well, from the Kongsberger technique after World War I to the Daescher technique in the 1950s to the current V-style from 1985 onwards. The cross-country skiing technique would switch from classical to freestyle for all competitions beginning in 1985, but the biggest change would occur at the 1988 Winter Olympics in the scoring with the Gundersen method, meaning the 15km cross country portion would go from an interval start race to a pursuit race, so that whoever crossed the finish line first won the event. The team event with a 3 x 10km cross country relay started at the 1988 Winter Olympics, changing to the current 4 x 5km cross-country relay at the 1998 Winter Olympics. The 7.5km sprint event was added at the 2002 Winter Olympics. Nordic combined remains a men's only event as of the 2010 Winter Olympics. For the 2010 Winter Games, the 15km Individual Gundersen which consisted of 2 jumps from the normal hill followed by 15km cross country will be replaced by a 10km individual normal hill event which will consist of one jump from the individual normal hill following by 10km of cross country using the Gundersen system while the 7.5km sprint will be replaced by the 10km individual large hill event. - Dmitry Sinitzyn ( born October 29 , 1973 ) is a Russian nordic combined athlete who competed from 1997 to 2002 . He won two bronze medals at the 1999 FIS Nordic World Ski Championships in Ramsau ( 15 km individual and 4 x 5 km team ) . Sinitzyn also earned three individual career victories in 1997 ( two individual , one sprint ) . - The FIS Nordic Combined World Cup is a Nordic combined competition organized yearly by FIS, representing the highest level in international competition for this sport. It was first arranged for the 1983/84 season. Team event was first time held in 1999/00 season. The FIS race director is a Norwegian ex ski jumper and ex world record holder Lasse Ottesen. - Nordic combined is a winter sport in which athletes compete in cross-country skiing and ski jumping. Nordic combined at the Winter Olympics and the FIS Nordic Combined World Cup are ongoing. - Ski jumping is a form of Nordic skiing in which athletes descend a specially constructed takeoff ramp (known as the "inrun"), jump from the end of it (the "table") with as much power as they can generate, and "fly" as far as possible down a steeply sloped hill. Points are awarded for distance and style by five judges, with competition sanctioned by the International Ski Federation (FIS). To enable the athletes (who are known as "ski jumpers") to effectively glide such long distances and land safely, the skis they use are considerably wider and longer than their cross-country and alpine skiing counterparts. Ski jumping is predominantly a winter sport and has been part of the Winter Olympic Games since its inception in 1924 for men and since 2014 for women. Since 1954 it is possible to ski jump in summer on artificial surfaces made from plastic. Along with cross-country skiing, ski jumping is one of two sports which form the Nordic combined discipline. Holmenkollbakken in Oslo is the holy place of this sport, which is most popular in Austria, Germany, Finland, Japan, Norway, Poland and Slovenia. - A winter sport or winter activity is a recreational activity or sport which is played during cold weather months. Most such sports are variations of skiing, ice skating and sledding. Traditionally such sports were only played in cold areas during winter, but artificial snow and artificial ice allow more flexibility. Artificial ice can be used to provide ice rinks for ice skating, ice hockey and bandy in a milder climate.
