题目分析：
本题十分简单，主要考查了比较的相关用法。
选项分析：
A选项：unlike连接的两者需要在逻辑上可比。本题的对比对象应该为earlier works on slavery和Blassingame's innovative study。所以，不能在earlier works on slavery前加that of。
B选项：本选项比较对象错误同选项(A)。
C选项：本选项的比较对象依然是有问题的。主句的主语是Blassingame，而unlike身后连接的是作品，很显然作品是不能和人去作对比的。
D选项：Correct. 本选项在语法和逻辑上均是正确的。
E选项：本选项比较对象错误同选项(C)。
对比对象应该为earlier works on slavery和Blassingame's innovative study
