答案解析： 

1. comparative→comparable。当仅仅表达“比较的，比较性的”意思，而没有涉及到具体的比较时，应该用第一个词，但是当设计到具体的两者之间的比较时，则应该使用comparable。此句属于第二种情况。

2. effects→affects。“effect”当作为动词使用时，表示“产生，引起，实现”的意思，作为名词时才是“影响，效果”，显然不符合，应该使用affect，意思是“影响”。

3. big→high。

4. unimaginative→unimaginable。该句中所要表达的是“难以想象的”，而unimaginative是“没有想像力的”意思，不符合句意。

5. nineteen→nineteenth。

6. high→highly。

7. remain→leave。

8. risen→raised。

9. mean→means。

10. international→national。表示“国防”的意思时应该使用national defense。
