OG 122 求助

season5924

122.    A wildlife expert predicts that the reintroduction of the
caribou into northern Minnesota would fail if the density
of the timber wolf population in that region is more
numerous than one wolf for every 39 square miles.
(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
were more numerous

我觉得这是对未来的预测，所以可以用虚拟语气would,而不应该用will.

OG解释是对的，timber wolf density你直译的话是"大灰狼密度“。。大灰狼的什么密度呢？？难道是和水密度，酒精密度一样吗。。

B will happen if A happen

请问C选项为什么og解释说“timber wolf density does not clearly refer to the population"?

为什么我觉得density比population 来的更准确呢，因为题目中more than的是“one wolf for every 39 square miles” 这不是density吗

预测的是未来的东西，当然是用will
provided没有if好
而且E中if条件句用的是were  错。OG中反复强调if X happen ，Y will happen  ；if X happened，Y would happen

试着解释一下
是对未来的预测，所以用主将从现，白勇上说：表示与将来的事情相反，if从句谓语用should+动词原型，主句谓语用would（第二三人称）+动词原形。
而且个人认为，gmat中考核虚拟语气的点大多集中在，表建议、命令、要求的动词后面的宾语从句虚拟，因为要省略should直接用动词原形，所以在形式上很容易让人误以为主谓不一致而排除掉正确答案
个人意见，请nn们指教
