In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw—having extracted them from the mouths of his slaves.
That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong—and yet most did little to fight it.

選項分析:[D]第一段說了一個不被大多數人所知道的事實,正是呼應第二段開頭的這個觀點,故為正解。[C]是根據第二段第二句所設置的干擾選項。排除它有兩個方法:(1)選項中出現的是role of slaves,而原文中出現的是roles slavery played,已經偷換概念了。(2)but之后的觀點就該和之前的觀點不同了,例子也應該是為but前的觀點服務的,而不是為but后的觀點服務的。[B]自我總結的主觀臆斷選項,不否認這里能看出很殘忍,但是這個例子不是為說明殘忍而寫的。[A]也同樣,為自我總結的主觀臆斷選項。
