Document 3: Trolley park: In the United States, trolley parks, which started in the 19th century, were picnic and recreation areas along or at the ends of streetcar lines in most of the larger cities. These were precursors to amusement parks. These trolley parks were created by the streetcar companies to give people a reason to use their services on weekends. These parks originally consisted of picnic groves and pavilions, and often held events such as dances, concerts and fireworks. Many eventually added features such as swimming pools, carousels, Ferris wheels, roller coasters, sports fields, boats rides, restaurants and other resort facilities to become amusement parks. Various sources report the existence of between 1,500 and 2,000 amusement parks in the United States by 1919.

Document 5: Amusement park: An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects.
