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
induce is parallel to heat or 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
On the GMAT, enough that is considered unidiomatic.
Eliminate B, C and D.
A: enough to affect the trajectories of ballistic missiles, induce electric currents.
Here, a conjunction such as and is required before induce.
Eliminate A.
The correct answer is E.
E: Displays can heat the atmosphere over the arctic enough to affect the trajectories of ballistic missiles and induce electric currents.
Here, induce is intended to be parallel with to affect:
enough TO AFFECT and INDUCE.
If induce were intended to be parallel with can heat, the sentence would read as follows:
Displays CAN HEAT the atmosphere over the arctic enough to affect the trajectories of ballistic missiles and CAN INDUCE electric currents.

Hi GMATGuruNY ,A: enough to affect the trajectories of ballistic missiles, induce electric currents.
Here, a conjunction such as and is required before induce.
Eliminate A.
Everything is clear, just a quick question. Beside parallelism is there any other that we need conjunction?
Please explain sir.
Many thanks in advance.

Hi GMATGUruNY ,
No sir, not every possible usage of conjunction. I just need to know that why AND is necessary in OA?
Thanks for your reply and sorry for not clearing.
Many thanks in advance.
