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.

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.

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.

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: late 19th century
