OG12 SC19题

The Iroquois were primarily planters, but supplementing their cultivation of maize, squash, and beans with fishing and hunting.
(A) but supplementing
(B) and had supplemented
(C) and even though they supplemented
(D) although they supplemented
(E) but with supplementing

OG解释：even though creates a sentence fragment.
why？even though可以做连词啊。

感谢指点。

even though 叫做从属连词，它必须引导一个从句，而不能单独成为一个完整的句子
完整的句子——A句，even though B句      其中A是主句，B是从句，合起来才是完整的句子
C里面 and是并列连词，连接两个完整的句子，显然even though 不是一个完整的句子，他只是一个从句。。。。。。。
