The historian Frederick J. Turner wrote in the 1890’s that the agrarian discontent that had been developing steadily in the United States since about 1870 had been speeded by the closing of the internal frontier -- that is, the depletion of available new land needed for further expansion of the American farming system. Not only was Turner’s thesis influential at the time, it was later adopted and elaborated by other scholars, such as John D. Hicks in The populist Revolt (1931). Actually, however, new lands were taken up for farming in the United States throughout and beyond the nineteenth century. In the 1890’s, when agrarian discontent had become most acute, 1,100,000 new farms were settled, which was 500,000 more than had been settled during the previous decade. After 1890, under the terms of the Homestead Act and its successors, more new land was taken up for fanning than had been taken up for this purpose in the United states up until that time. It is true that a high proportion of the newly fanned land was suitable only for grazing and dry farming, but agricultural practices had become sufficiently advanced to make it possible to increase the profitability of farming by utilizing even these relatively barren lands.
The emphasis given by both scholars and statesmen to the presumed disappearance ’of the American frontier helped to obscure the great importance of changes in the conditions and consequences of international trade that occurred during the second half of the nineteenth century. In 1869 the Suez Canal was opened and the first transcontinental railroad in the United States was completed. An extensive network of telegraph and telephone communications was spun: Europe was connected by submarine cable with the United States in 1866 and with South America in 1874. By about 1870 improvements in agricultural technology made possible the full exploitation of areas that were most suitable for extensive farming on a mechanized basis. Huge tracts of land were being settled and farmed in Argentina, Australia, Canada, and in the American West, and these areas were joined with one another and with the countries of Europe into an interdependent market system. As a consequence, agrarian depressions no longer were local or national in scope, and they struck several nations whose internal frontiers had not vanished or were not about to vanish. Between the early 1870’s and the 1890’s the mounting agrarian discontent in America paralleled the almost uninterrupted decline in the prices of American agricultural products on foreign markets. Those staple-growing farmers in the United States who exhibited the greatest discontent were who had become most dependent on foreign markets for the sale of their products. In so far as Americans had been deterred from taking up new land for farming, it was because market conditions had made this period a perilous time in which to do so.

The author implies that the cause of the agrarian discontent was（）

A:masked by the vagueness of the official records on newly settled farms. B:overshadowed by disputes on the reliability of the existing historical evidence. C:misidentified as a result of influential but erroneous theorizing. D:overlooked because of a preoccupation with market conditions.

Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs’ fossils(恐龙化石) because dinosaurs died out millions of years ago.
It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils, Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck (陷入) all at once. Or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.
Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. "That’s pretty much settled at this point," says Paul Sereno. A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.
As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs—birds and crocodiles—for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.
There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.
What is pretty much settled according to Paul Sereno

A:Half of the dinosaurs lived alone. B:Most dinosaurs moved long distances. C:Many dinosaurs settled in the north. D:Some dinosaurs lived in big groups.
