参考答案

正确答案：C
解析：细节题。根据题干关键词Professor Henry和younger generation's political strength定位第三段第一句Henry Flores，a political-science professor at St. Mary's University，credits this younger generation's political strength to their embrace of technology．(Henry Flores是圣玛丽大学的一名政治科学教授。他将年轻人的政治优势归因于他们对科技的充分了解。)随后点出“[The Internet]exposes them to more thinking，”he says，“and groups that are like-minded in different parts of the country start to come together．”(他说：“因特网使他们接触了更多的思想，也使美国不同地区志趣相投的人开始聚集起来。”)故选C。
