Question: Information: - Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Oresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas. - 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 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. - Northern Europe is the northern part or region of Europe. Although no definitive borders or definition exists for the term, geographically, Northern Europe may be considered to consist approximately of all of Europe above the 52nd parallel north; which includes (from west to east) most or all of: Iceland, the Republic of Ireland, the Isle of Man, the United Kingdom, the Faroe Islands, the Netherlands, northern Germany, Denmark, Norway, Sweden, northern Poland, Finland, Estonia, Latvia, Lithuania and northwest Russia. However, narrower definitions may also be used based on other geographical factors, such as climate and ecology. Greenland, geographically a part of North America, is politically a part of the Kingdom of Denmark, and may be included depending on the definition. - 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. - The FIS Nordic World Ski Championships 1934 took place on February 20 -- 25 , 1934 in Solleftea , Sweden . After reading the paragraphs above, choose the best answer for the entity that related to 'fis nordic world ski championships 1934' with the relationship of 'sport'. Choices: - nordic combined - nordic skiing - ski jumping - skiing - sport - united kingdom
Answer: skiing

Question: Information: - A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components capacitors, resistors or active devices are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate. - Through-hole technology, also spelled "thru-hole", refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines. - Surface - mount technology ( SMT ) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards ( PCBs ) . An electronic device so made is called a surface - mount device ( SMD ) . In the industry it has largely replaced the through - hole technology construction method of fitting components with wire leads into holes in the circuit board . Both technologies can be used on the same board , with the through - hole technology used for components not suitable for surface mounting such as large transformers and heat - sinked power semiconductors . An SMT component is usually smaller than its through - hole counterpart because it has either smaller leads or no leads at all . It may have short pins or leads of various styles , flat contacts , a matrix of solder balls ( BGAs ) , or terminations on the body of the component . - An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components. After reading the paragraphs above, choose the best answer for the entity that related to 'surface-mount technology' with the relationship of 'subclass of'. Choices: - assembly - board - electronic component - printed circuit board - technology
Answer:
electronic component
