Question: Information:  - The Nordic combined events have been contested at the Winter Olympic Games since 1924. The first competition involved 18 km 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 18 km cross-country skiing. The cross-country skiing portion was reduced to 15 km 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 15 km 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 10 km cross country relay started at the 1988 Winter Olympics, changing to the current 4 x 5 km cross-country relay at the 1998 Winter Olympics. The 7.5 km 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 15 km Individual Gundersen which consisted of 2 jumps from the normal hill followed by 15 km cross country will be replaced by a 10 km individual normal hill event which will consist of one jump from the individual normal hill following by 10 km of cross country using the Gundersen system while the 7.5 km sprint will be replaced by the 10 km individual large hill event.  - Geir Andersen ( born February 12 , 1964 ) is a Norwegian nordic combined skier who competed from 1983 to 1989 . He won three medals at the FIS Nordic World Ski Championships with one gold ( 1984 : 3 x 10 km team ) and two silvers ( 1985 : 15 km individual , 3 x 10 km team ) . Andersen also finished 10th in the individual event at the 1984 Winter Olympics in Sarajevo . He had six individual victories in his career from 1984 to 1985 .  - 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.  - 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.  - 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.  - The FIS Nordic World Ski Championships have been held in various numbers and types of events since 1925 for men and since 1954 for women. Championship events include nordic skiing's three disciplines: cross-country skiing, ski jumping, and nordic combined (the latter being a combination sport consisting of both cross-country and ski jumping). From 1924 to 1939, the World Championships were held every year, including the Winter Olympics. After World War II, the World Championships were held every four years from 1950 to 1982. Since 1985, the World Championships have been held in odd-numbered years.  - Nordic skiing pertains to skiing disciplines that use equipment where the toe of the ski boot is fixed to the binding in a manner that allows the heel to rise off the ski, unlike Alpine skiing, where the boot is attached to the ski from toe to heel. Recreational disciplines include cross-country skiing and Telemark skiing.  - 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.    Given the paragraphs above, decide what entity has the relation 'place of birth' with 'oslo'.
