OG 11 70 Displays of the aurora borealis, or "northern lights," can heat the atmosphere over the Arctic enough to affect the trajectories of ballistic missiles, induce
electric currents that can cause blackouts in some areas and corrosion in north-south pipelines.

(A) to affect the trajectories of ballistic missiles, induce

(B) that the trajectories of ballistic missiles are affected, induce

(C) that it affects the trajectories of ballistic missiles, induces

(D) that the trajectories of ballistic missiles are affected and induces

(E) to affect the trajectories of ballistic missiles and induce

OG说 A 的induce语法可以，只是the second effect appears to be part of the first one ,which is not true才排除

不应该是inducing或 and induce 才对吗

OG11 可真不好找。

Grammatical construction + Logical predication
This sentence describes two effects of the aurora borealis. It heats the atmosphere enough to affect
x and (to) induce y; the preposition to does not need to be repeated because it is understood. The conjunction and is necessary to show that the two effects are equal and separate. When they are separated only by a comma, the second effect appears to be part of the first one, which is not true.
A   To affect and (to understood) induce should be joined by the conjunction and rather than separated by a comma.

B   The correct idiom is can heat ... enough to
affect, that violates the idiom and introduces
an illogical sequence of verbs (are affected,
induce)
C   The correct idiom is can heat ... enough to affect, that violates the idiom; the verbs should be joined by a conjunction rather than separated by a comma
D   That violates the correct idiom can heat ... enough to affect, the verbs illogically change tenses
E   Correct. In this sentence, the two effects are shown to be equal and separate in a grammatical construction that correctly joins to affect and (to understood) induce.

这是OG11是对这道题的解释，想必是你手上的11版本新一点，把解释改过了。因为实在是没法理解OG会这样把两个动词用逗号链接。这样的错误答案有很多的。

对了，LZ可以把你的手里的OG解释贴上来看看吗，这样可以对比一下，说不定能发现更多有趣的东西。

Choice A incorrectly separates the two infinitives to affect and [to] induce with a comma when it should compound them with and, as does E, the best choice.
比选项啊，A E 的区别在于and，to affect````````，`````````````to induce````符合to do A and (to) do B,
只剩两个选项时就得比选项，看哪个更好，
