Task: Question Answering
Input (English): Context_1 : The MVG Class A is an electric multiple unit (EMU) train type operated by the Münchner Verkehrsgesellschaft on the Munich U-Bahn system. It is the first and oldest type of rolling stock in service on the Munich U-Bahn. The prototypes were delivered in 1967, and the full-production units from 1970 until 1984. A derivative of the Class A, the VAG Class DT1, is in service on the Nuremberg U-Bahn system. Context_2 : Jewellery (British English) or jewelry (American English) consists of small decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants and bracelets. Jewellery may be attached to the body or the clothes, and the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal, often combined with gemstones, has been the normal material for jewellery, but other materials such as shells and other plant materials may be used. It is one of the oldest type of archaeological artefact – with 100,000-year-old beads made from "Nassarius" shells thought to be the oldest known jewellery. The basic forms of jewellery vary between cultures but are often extremely long-lived; in European cultures the most common forms of jewellery listed above have persisted since ancient times, while other forms such as adornments for the nose or ankle, important in other cultures, are much less common. Context_3 : Alkaline anion exchange membrane fuel cells (AAEMFC) also known as hydroxide exchange membrane fuel cells (HEMFCs), anion-exchange membrane fuel cells (AEMFCs), or alkaline membrane fuel cells (AMFCs), are a type of alkaline fuel cells (AFCs). Alkaline fuel cells, one of the oldest type of fuel cell, operate between ambient temperature and 90 °C with an electrical efficiency higher than the other fuel cells such as proton exchange membrane fuel cells (PEMFC), solid oxide fuel cells and phosphoric acid fuel cells. Alkaline anion exchange membrane fuel cells (AAEMFCs) are functionally similar to AFCs, the difference being AAEMFCs employ a solid polymer electrolyte while AFCs use aqueous potassium hydroxide (KOH) as an electrolyte. Context_4 : Cannon Ball is a wooden roller coaster at Lake Winnepesaukah amusement park. Designed by John C. Allen and built by Philadelphia Toboggan Company (today called Philadelphia Toboggan Coasters), the roller coaster opened in 1967 and quickly became one of the signature attractions at the park. It is one of four roller coasters at the park. Context_5 : An old mill is a type of amusement park ride with unaccompanied boats floated on guideways through dark tunnels. These themed dark rides originated in the late 19th century and are known by a variety of names, including tunnel of love and river cave. While generally considered a gentle ride, a variation that ends with a climactic splashdown, similar to the modern-day log flume, is known as a mill chute. Context_6 : Lake Winnepesaukah, commonly known as Lake Winnie, is an amusement park located in Rossville, Georgia, just south of Chattanooga, Tennessee. Carl and Minette Dixon opened the park to over 5,000 guests on June 1, 1925. They named it after the Native American word "Winnepesaukah", meaning “bountiful waters” or “beautiful lake of the highlands”. The park originally featured the largest swimming pool in the southeastern United States, which debuted in 1926 and was later removed. Its Boat Chute attraction, designed by Carl Dixon, opened in 1927 and is the oldest mill chute water ride of its kind still in operation in the United States. Context_7 : A metal zipper is a zipper, zip, zip fastener or fly with its binding edges consisting of individual pieces of metal that are molded into shape and set at regular intervals on the zipper tape. Metal zippers are mainly made of brass, nickel and aluminium, and given their durability, they are mostly used in jeans, work-wear, heavy luggage and heavy-duty garments that must withstand high strength and tough washing. The metal zipper is the oldest type of workable zipper, having been invented by Gideon Sundback as an improvement of Whitcomb Judson's "Clasp Locker" that majorly consisted of a hook-and-eye shoe fastener. Context_8 : The English barn, or three bay barn, is a barn style that was most popular in the northeast region of the USA, but are the most widespread barn type in America. This barn type is, with the New World Dutch barn the oldest type and has been called the "...grandfather of the American barn." New barns in this style were constructed for over a century, from the 1770s through the 1900s. Context_9 : Chute Lake is a small lake on the east side of Okanagan Mountain, in the Okanagan Valley in the southern interior of British Columbia. The only access roads are the Chute Lake Forestry Road, leading to Naramata in the south, and the Kettle Valley Rail Trail, leading to Kelowna in the north. The Chute Lake Resort is located on the lake's southwest shore. Context_10 : Shoot the Chute is an amusement ride consisting of a flat-bottomed boat that slides down a ramp or inside a flume into a lagoon. Unlike a log flume, a Shoot the Chute ride generally has larger boats and one single drop. fact_1 :  The park originally featured the largest swimming pool in the southeastern United States, which debuted in 1926 and was later removed. fact_2 :  These themed dark rides originated in the late 19th century and are known by a variety of names, including tunnel of love and river cave. Question: Lake Winnepesaukah's Boat Chute is the oldest type of ride that originated when? 
Output (English): late 19th century
