答案：

1 将affect改为effect,affect是动词。effect是名词。

2 将suggests改为 suggesting,这是一个以while引导的从句，其中suggest应该与capturing并列。

3在fact后面加上that,因为引导同位语从句的关系词不可以省略。

4 将their改为its,这里its指代单数名词caricature

5 将century改为复数形式

6 将was省略,appear是不及物动词，不应用于被动语态。

7 将his改为their,这里指代复数名词 the caricaturists

8 将primary改为primarily,primarily在这里做状语，修饰不定式短语

9 将close改为比较级形式closer,从后面的连词than，可以看出，这里使用了比较状语从句

10 将amusing改为 amused,主语subject(受攻击的人)和amuse的逻辑关系是动宾关系，应使用过去分词形式。
