参考答案
正确答案：A
解析：这是一道篇章理解题。“What，according to the passage，makes the research conducted by the scientists at the Oregon Department of Health so unique?”(根据此文，什么使得俄勒冈卫生部科学家的研究如此与众不同呢?)unique意即"being the only one of its type；without parallel"，独一无二的，无双的。题干是对该研究的定性和评价(独特的)，考生则应该从文中寻找对此研究的评价性语句。第三段中，“We were somewhat surprised by the immediacy of the effect and the fact that we could measure the average hourly increase．”(影响如此迅速，我们甚至可以测量出每小时的增长值，这不禁令人有些吃惊)。令人吃惊的也正是与众不同的，这句话的后半部分(the fact that we could measure the average hourly increase)恰好与A选项相吻合，故选A。
