122.

(A) would fail if the density of the timber wolf
population in that region is more numerous
(B) would fail provided the density of the timber wolf
population in that region is more
(C) should fail if the timber wolf density in that
region was greater
(D) will fail if the density of the timber wolf
population in that region is greater
(E) will fail if the timber wolf density in that region

139.

improve

OG解释里，122题里说要用will来表示确定性情况，但是在139题里却说要用would来表示不确定性，晕死，两道题都是在讲预测和不确定性啊，到底要用will还是would呢？

求解释

The subjunctive verb form would expresses remoteness and thus casts some doubt on the likelihood of x.
The verb form will fail expresses the likelihood x with greater certainty.

OG里Q122的解释，will比would可能性更高。

商业市场情况因素比较复杂，科学家对于自然的分析确定性更高，狼多了鹿被吃的数量也多。

。。。。我也不太知道了。我最近看大全发现大全里的解释是按时态走的，没有说关于确定性的事

可是OG上的解释没有说是因为时态决定will还是would啊？而且按照常理，predict的东西更可能不确定，而announced则更具确定性啊？

我的理解是122题专家们很确定如果密度大于39，reintroduction就不可能实现
139题公司自己也并不很清楚公司的improvement，不确定的。
但我觉得这个will和would根据certainty确实挺难判断的，我还有一种想法，不知道对不对，122题是一般现在时predicts，所以用will，139题是过去时announced所以用would

看主句时态
predicts=will
announced=would

第一个题the density不能用numerous修饰，第二个题expected it to不对
