1. The techniques now available to livestock breeders will continue to be -----, but will probably be----by new ones under development.
A  refined
B  used
C  fruitful
D  replaced
E  upgraded
F  supplemented
第一个空我明白,第二个空对于E选项我有疑问.老师说continue表示未来也会用,但是upgraded不是也可以表示未来也用吗?
2. Unenlightened authoritarian managers rarely recognize a crucial reason for the low levels of serious conflict among members of democratically run work groups: a modicum of tolerance for dissent often prevents-----
答案是schism. 我这个句子看不太懂,尤其是红色那里.希望有人帮我分析一下句子结构.

妹子刚开始准备G,希望在这里能和大家一起努力:)

1、“by new ones”决定了不能用upgrade
2、翻译如下：

那些很集权的经理们很少意识到一个很重要的原因，为什么在民主的工作团体里严重冲突发生得很少，那就是对不同意见的适度容忍可以防止分裂的发生

Unenlightened authoritarian managers rarely recognize
a crucial reason for the low levels of serious conflict among members of democratically run work groups: a modicum of tolerance for dissent often prevents schism.


红色的是主干，其余都是修饰reason的
