陈琦填空的两道题

nourrissonUID：3420968

Section 4
6. Compared with their parties, politicians are (   ): they are considerably less enduring than the organizations in which they function.
答案是transitory，我理解；但为什么fickle不行呢？韦氏的解释是marked by lack of steadfastness, constancy, or stability...求问我钻到牛角尖的哪里了？

3. Powerful as they are, the (   ) songs the artist is best known for might sting more and even greater emotional complexity if one felt that his criticisms were aimed at himself as well as at his unnamed foes.
答案是accusatory，求解释@@

谢谢啊！
