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: Galicia is poetically known as the "country of the thousand rivers" ("o pais dos mil rios"). The largest and most important of these rivers is the Minho, known as O Pai Mino (Father Minho), 307.5 km (191.1 mi) long and discharging 419 m3 (548 cu yd) per second, with its affluent the Sil, which has created a spectacular canyon. Most of the rivers in the inland are tributaries of this fluvial system, which drains some 17,027 km2 (6,574 sq mi). Other rivers run directly into the Atlantic Ocean as Lerez or the Cantabrian Sea, most of them having short courses. Only the Navia, Ulla, Tambre, and Limia have courses longer than 100 km (62 mi).
