Question: Information:  - Lille  is a city in northern France, in French Flanders. On the Deûle River, near France's border with Belgium, it is the capital of the Hauts-de-France region and the prefecture of the Nord department.  - A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names.  - The term cult usually refers to a social group defined by their religious, spiritual, or philosophical beliefs, or common interest in a particular personality, object or goal. The term itself is controversial and has divergent definitions in popular culture and in academia and has been an ongoing source of contention among scholars across several fields of study. In the sociological classifications of religious movements, a cult is a social group with socially deviant or novel beliefs and practices, although this is often unclear. Other researchers present a less-organized picture of cults on the basis that cults arise spontaneously around novel beliefs and practices. The word "cult" has always been controversial because it is (in a pejorative sense) considered a subjective term, used as an "ad hominem" attack against groups with differing doctrines or practices. Cults range in size from local groups with a few members to international organizations with millions.  - The Orge is a 53 - kilometre ( 33 mi ) long river in France , left tributary of the Seine .

Answer: orge
input: Please answer the following: Information:  - A mountain bike or mountain bicycle (abbreviated Mtn Bike, MTB; or ATB, for all-terrain bicycle) is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. These typically include suspension on the frame and fork, large knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction.  - Downhill is an alpine skiing discipline. Unlike the other alpine skiing events, slalom, giant slalom, super giant slalom, and combined, which emphasize turning and technique, downhill is more about speed. Speeds of up to are common in international competition. Athletes must have an aerodynamically efficient tuck position to minimize drag and increase speed.  - Cycle sport is competitive physical activity using bicycles. There are several categories of bicycle racing including road bicycle racing, time trialling, cyclo-cross, mountain bike racing, track cycling, BMX, and cycle speedway. Non-racing cycling sports include artistic cycling, cycle polo, freestyle BMX and mountain bike trials. The Union Cycliste Internationale (UCI) is the world governing body for cycling and international competitive cycling events. The International Human Powered Vehicle Association is the governing body for human-powered vehicles that imposes far fewer restrictions on their design than does the UCI. The UltraMarathon Cycling Association is the governing body for many ultra-distance cycling races.  - George David Atherton , known as Gee Atherton ( born 26 February 1985 , near Salisbury , England ) is a professional racing cyclist specialising in downhill and four cross mountain bike racing , and is a multiple national champion , multiple World Cup winner , 2010 Downhill World Cup Champion , and 2010 & 2014 Downhill World Champion .  - Alpine skiing, or downhill skiing, is the sport or recreation of sliding down snow-covered hills on skis with fixed-heel bindings. It is characterized by the requirement for mechanical assistance getting to the top of the hill, since the equipment does not allow efficient walking or hiking, unlike cross-country skis which use free-heel bindings. It is typically practiced at ski resorts which provide services such as ski lifts, artificial snow making and grooming, first aid, and restaurants. Back-country skiers use alpine skiing equipment to ski off the marked pistes, in some cases with the assistance of snowmobiles, helicopters or snowcats. Alpine skiing has been an event at the Winter Olympic Games since 1936 (except for the 1940 games).  - The Union Cycliste Internationale, commonly known by the acronym UCI, is the world governing body for sports cycling and oversees international competitive cycling events. The UCI is based in Aigle, Switzerland.  - Mountain bike racing (shortened MTB or ATB racing) is a competitive cycle sport held on off-road terrain. The Union Cycliste Internationale (UCI) recognised the discipline relatively late in 1990, when it sanctioned the world championships in Durango, Colorado. The first UCI Mountain Bike World Cup series took place in 1988. Its nine-race circuit covered two continentsEurope and North Americaand was sponsored by Grundig. Cross-country racing was the only World Cup sport at this time. In 1993, a six-event downhill World Cup was introduced. In 1996, cross-country mountain biking events were added to the Olympic Games. In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA.
