参考答案

正确答案：B
解析：本题的四个选项中，只有B项为正确答案。这可从文中的"There is a strong demand for moral revival and for some devotion that is vast enough and yet personal enough to enlist the devotion of all．Inthe past it has been only in a way in defense of their own country and their own ideals that any people have been able to devote themselves wholeheartedly．"推知，即"Lack of devotion"正确。
