Input: Consider Input: After 1870, the new railroads across the Plains brought hunters who killed off almost all the bison for their hides. The railroads offered attractive packages of land and transportation to European farmers, who rushed to settle the land. They (and Americans as well) also took advantage of the homestead laws to obtain free farms. Land speculators and local boosters identified many potential towns, and those reached by the railroad had a chance, while the others became ghost towns. In Kansas, for example, nearly 5000 towns were mapped out, but by 1970 only 617 were actually operating. In the mid-20th century, closeness to an interstate exchange determined whether a town would flourish or struggle for business.

Output: after about what year did railroads bring hunters to the great plains?


Input: Consider Input: In the early 1950s, Universal set up its own distribution company in France, and in the late 1960s, the company also started a production company in Paris, Universal Productions France S.A., although sometimes credited by the name of the distribution company, Universal Pictures France. Except for the two first films it produced, Claude Chabrol's Le scandale (English title The Champagne Murders) and Romain Gary's Les oiseaux vont mourir au Pérou (English title Birds in Peru), it was only involved in French or other European co-productions, the most noticeable ones being Louis Malle's Lacombe, Lucien, Bertrand Blier's Les Valseuses (English title Going Places), and Fred Zinnemann's The Day of the Jackal. It was only involved in approximately 20 French film productions. In the early 1970s, the unit was incorporated into the French Cinema International Corporation arm.

Output: What was the name of the Universal production company based in Paris?
