Without allies, its only course would be to block the decision by citing "vital national inter-ests"-the sort of profoundly unEuropean thing that Britain might do, but which France would rather not.
A、lesson
B、progress
C、policy
D、problem
【正确答案】:C
【名师解析】:在题目中,关键短语 "its only course" 暗示了在没有盟友的情况下,所讨论的国家或组织将采取的行动或方法。选项中 "course" 与 "policy" 意义最为接近,因为 "policy" 可以指一个国家或组织在特定情况下采取的行动方针或策略。其他选项 "lesson"(课程或教训)、"progress"(进步或发展)和 "problem"(问题)与 "course" 的含义不符。因此,正确答案是选项C "policy"。
