参考答案

正确答案：A
解析：题目考查梅森对政治活动的看法。“He was at all times a man of public spirit，but politics was nevera way of life，never for long his central concern．It took a revolution to pry him away from home andfamily at Gunston Hall，mobilize his skill and energy for constitutional construction，and transform. him．”通过这段话可知，Mason并非对政治情有独钟，虽然他是一个很有爱国心的人，除非因为争取独立而革命，他才会义无反顾地投身政治。据此判断，应选择A。
