Which one of the following best states the main idea of the passage? A. McLaughlin's studies of the impact of missionaries on Cherokee culture during the 1820s are fundamentally flawed, since McLaughlin ignores the greater impact of White resident traders in the eighteenth century. B. Though his work is limited in perspective, McLaughlin is substantially correct that changes in Cherokee culture in the 1820s were mediated by the Cherokee themselves rather than simply imposed by the missionaries. C. Although McLaughlin is correct in asserting that cultural changes among the Cherokee were autonomous and so not a result of the presence of missionaries, he overemphasizes the role of intertribal conflicts. D. McLaughlin has shown that Cherokee culture not only flourished during and after the 1820s, but that changes in Cherokee culture during this time developed naturally from elements already present in Cherokee culture. E. Although McLaughlin overlooks a number of relevant factors in Cherokee cultural change in the 1820s, he convincingly demonstrates that these changes were fostered primarily by missionaries.
