Q: Information:  - Richard Douglas `` Dick '' Fosbury ( born March 6 , 1947 ) is a retired American athlete who competed in the high jump , and is considered one of the most influential athletes in the history of track and field . Besides winning a gold medal at the 1968 Olympics , he revolutionized the high jump event , inventing a unique `` back - first '' technique , now known as the Fosbury Flop , adopted by almost all high jumpers today . His method was to sprint diagonally towards the bar , then curve and leap backwards over the bar , which gave him a much lower center of mass in flight ( it was actually below his body ) than traditional techniques . He continues to be involved in athletics and serves on the executive board of the World Olympians Association In 2014 Fosbury ran for a seat in the Idaho House of Representatives .  - Cross country running is a sport in which teams and individuals run a race on open-air courses over natural terrain such as dirt or grass. Sometimes the runners are referred to as "harriers" (dogs). The course, typically long, may include surfaces of grass, and earth, pass through woodlands and open country, and include hills, flat ground and sometimes gravel road. It is both an individual and a team sport; runners are judged on individual times and teams by a points-scoring method. Both men and women of all ages compete in cross country, which usually takes place during autumn and winter, and can include weather conditions of rain, sleet, snow or hail, and a wide range of temperatures.  - The 1968 Summer Olympics (Spanish: "Juegos Olímpicos de Verano de 1968"), officially known as the Games of the XIX Olympiad, were an international multi-sport event held in Mexico City, Mexico, in October 1968.  - The World Olympians Association (WOA) is an association of olympic athletes ("Olympians") from all over the world, to promote the dissemination of Olympic ideals and fair play, advance environmental protection, educate against doping and drug use, supply educational resources, work against violence and intolerance, support diversity and equality, contribute to sport-related charities, host special hospitality centres, involve Olympians in social support, display positive role models, advance sport management and promote a culture of which sport is an important part.  - Road running is the sport of running on a measured course over an established road (as opposed to track and field and cross country running).  - Track and field is a sport which includes athletic contests established on the skills of running, jumping, and throwing. The name is derived from the sport's typical venue: a stadium with an oval running track enclosing a grass field where the throwing and jumping events take place. Track and field is categorised under the umbrella sport of athletics, which also includes road running, cross country running, and race walking.   - The Fosbury Flop is a style used in the athletics event of high jump. It was popularized and perfected by American athlete Dick Fosbury, whose gold medal in the 1968 Summer Olympics brought it to the world's attention. Over the next few years the flop became the dominant style of the event and remains so today.  Before Fosbury, most elite jumpers used the straddle technique, Western Roll, Eastern cut-off or even scissors jump to clear the bar. Given that landing surfaces had previously been sandpits or low piles of matting, high jumpers of earlier years had to land on their feet or at least land carefully to prevent injury. With the advent of deep foam matting high jumpers were able to be more adventurous in their landing styles and hence experiment with styles of jumping.    Given the paragraphs above, decide what entity has the relation 'participant of' with '1968 summer olympics'.

Q: Information:  - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly.  - A vending machine is a machine that dispenses items such as snacks, beverages, alcohol, cigarettes, lottery tickets to customers automatically, after the customer inserts currency or credit into the machine. The first modern vending machines were developed in England in the early 19th century and dispensed postcards. History. The earliest known reference to a vending machine is in the work of Hero of Alexandria, a first-century AD Greek engineer and mathematician. His machine accepted a coin and then dispensed holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened a valve which let some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight snapped the lever up and turned off the valve.  - An automat is a fast food restaurant where simple foods and drink are served by vending machines.  - Pierre Jaquet-Droz (17211790) was a Swiss-born watchmaker of the late eighteenth century. He lived in Paris, London, and Geneva, where he designed and built animated dolls, or automata, to help his firm sell watches and mechanical birds.  - Henri Maillardet ( 1745 -- 1830 , born Jean Henri Nicholas Maillardet ) , was a Swiss mechanician of the 18th century who worked in London producing clocks and other mechanisms . He spent a period of time in the shops of Pierre Jaquet - Droz , who was in the business of producing watches , clocks , and automata . With his brothers Jaques - Rodolphe and Jean David Maillardet , Henri produced a series of automata depicting magicians . In 1805 Henri Maillardet built a spring - activated automaton that draws pictures and writes verses in both French and English . The motions of the hand are produced by a series of cams located on shafts in the base of the automaton , which produces the necessary movement to complete seven sketches and the text . It is believed that this automaton has the largest cam - based memory of any automaton of the era . When first presented to the Franklin Institute in Philadelphia in 1928 , the automaton was of unknown origin . Once restored to working order , the automaton itself provided the answer when it penned the words `` written by the automaton of Maillardet '' . Maillardet died in Malines , Belgium , in 1830 where he is buried .  - A watchmaker is an artisan who makes and repairs watches. Since a majority of watches are now factory made, most modern watchmakers only repair watches. However, originally they were master craftsmen who built watches, including all their parts, by hand. Modern watchmakers, when required to repair older watches, for which replacement parts may not be available, must have fabrication skills, and can typically manufacture replacements for many of the parts found in a watch. The term clockmaker refers to an equivalent occupation specializing in clocks.    Given the paragraphs above, decide what entity has the relation 'occupation' with 'engineer'.
