[Q]: 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.
[A]: after about what year did railroads bring hunters to the great plains?


[Q]: Sarvastivada teachings—which were criticized by Nāgārjuna—were reformulated by scholars such as Vasubandhu and Asanga and were adapted into the Yogacara school. While the Mādhyamaka school held that asserting the existence or non-existence of any ultimately real thing was inappropriate, some exponents of Yogacara asserted that the mind and only the mind is ultimately real (a doctrine known as cittamatra). Not all Yogacarins asserted that mind was truly existent; Vasubandhu and Asanga in particular did not.[web 11] These two schools of thought, in opposition or synthesis, form the basis of subsequent Mahayana metaphysics in the Indo-Tibetan tradition.
[A]: What teaching were criticized by Nagarjuna?


[Q]: Although it was Russia that was punished by the Paris Treaty, in the long run it was Austria that lost the most from the Crimean War despite having barely taken part in it.:433 Having abandoned its alliance with Russia, Austria was diplomatically isolated following the war,:433 which contributed to its disastrous defeats in the 1859 Franco-Austrian War that resulted in the cession of Lombardy to the Kingdom of Sardinia, and later in the loss of the Habsburg rule of Tuscany and Modena, which meant the end of Austrian influence in Italy. Furthermore, Russia did not do anything to assist its former ally, Austria, in the 1866 Austro-Prussian War:433 with its loss of Venetia and more important than that, its influence in most German-speaking lands. The status of Austria as a great power, with the unifications of Germany and Italy was now severely questioned. It had to compromise with Hungary, the two countries shared the Danubian Empire and Austria slowly became a little more than a German satellite. With France now hostile to Germany, allied with Russia, and Russia competing with the newly renamed Austro-Hungarian Empire for an increased role in the Balkans at the expense of the Ottoman Empire, the foundations were in place for creating the diplomatic alliances that would lead to World War I.
[A]:
Who lost the most due to the Crimean War?
