OG12SC19The 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
正确选项为D
我只需要解释A就行了!
A 中的but 是错误使用?还是连接两个表语——planters 和supplementing ?
