The correct answer is “In the language of the venerated Calhoun I consider the disruption of the Union as a great though not the greatest calamity.”. In the Speech to the State Legislature of Mississippi given by Jefferson Davis (1862), Davis mainly argues that Mississippi should separate from the Union. Mississippi was the state he represented in the United States Senate. Because of his love to this state, Davis strongly believed in this separation. That is why the quote cited above as a correct answer is the excerpt from Jefferson Davis’s speech to the Mississippi Legislature that best expresses a major theme of his speech. In fact, in the previous lines to the excerpt quoted above, David argues that “Now, as in 1851, I hold separation from the Union by the State of Mississippi to be the last remedy—the final alternative.”, reassuring his position and the major theme of his speech.
