The displays can heat the atmosphere to do two things. 1. to affect the trajectories blah, blah and 2. ( to) induce electric currents blah blah . So an – and - is required between - missiles - induce - to complete the series with proper parallelism.
E is the correct answer.

+1 E
"enough to" is the idiom. B, C, and D out. There are two effects of these northern lights: affecting the trajectories of ballistic missiles AND inducing electric currents. AND is needed. E is the answer.

E [enough to..] and [the northern lights heat and induce] A implies that the missile induce[s] no
I chose A
I assumed "can heat the atmosphere over the arctic enough to affect the trajectories of ballistic missiles" to be a modifier modifying Aurora lights. Why is this wrong? So I read the question as "Displays of the aurora borealis, BLAH BLAH BLAH (modifier) , induce electric currents that can cause blackouts in some areas and corrosion in north-south pipelines.
So 'Displays' is plural and goes with 'induce' and by virtue of which other answer choices are wrong. What did I miss?

Hi ace312, I don't think "can heat the atmosphere over the arctic enough to affect the trajectories of ballistic missiles" is modifying Aurora lights. Consider below example (I just made up),
Sunlight from sun, can heat earth's surface - here Sunlight is heating earth's surface, not sun, the same way Displays are heating atmosphere, not the aurora borealis in the below example. Hope this clears your doubt or reply if you have more questions.

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 are affected and induces D.that the trajectories of ballistic missiles are affected and induces E. to affect the trajectories of ballistic missiles and induce
Now i dunno who to decide between A and E, Can someone help?

If the sentence uses "inducing" after comma in option A, will it be considered right?

Damn!! GMAT is a tricky test. The point is that we should never ever underestimate the need to read and understand the sentence! I choose A because the sentence was correct and parallel. Then when i saw the OA i realized " induce electric currents that can cause X (blackouts in some areas) and Y (corrosion in north-south pipelines)" need and before it to make it parallel with the first part .

can heat... enough to affect in A and E is more idiomatic than the use of the subordinate clause beginning with "that" in B, C, and D.
B - produces an illogical and ungrammatical statement by making induce parallel with the verb heat rather than with the appropriate form of the verb affect;
C - lacks agreement in using the singular pronoun it to refer to the plural noun displays
D is faulty because induces cannot fit grammatically with any noun in the sentence.
A incorrectly separates the two infinitives to affect and [to] induce with a comma when it should compound them with and, as does E.

Hi,
I'm absolutely on board with the two things and how they need to be connected but I can't make peace with this bit - "to" is an infinitive of purpose. Using "to" almost seems like the displays heat the atmosphere with the intention to 1. affect the trajectories ... 2. ( to) induce electric currents... but that isn't the intended meaning right. The meaning is that these two things CAN be a result of the displays.
Please help!

actually, the display can generate heat that is enough to do two things (or you can say, the display can generate enough heat that can cause two things) viz. 1. to affect the trajectories...... and 2. ( to) induce electric currents.........
These two effect of that heat is presented as 1. to affect the trajectories...... and 2. ( to) induce electric currents......... and they need to be in parallel form

Hi Rudra,
Thank you for your time. I understand the 2 things that "CAN" happen but GMAT is so strict about how intent and ability are expressed grammar wise - that's where I'm struggling with the use to the infinitive of purpose i.e to.
Best, Snigdha

Although I know you have asked specific experts to respond your query, I hope you will allow me to help you with it.
You are right, that "+to infinitive" is used to indicate intentions. So, the following sentence would fall under this usage:
I went to her place to collect my parcel. - I went there with the intention to achieve something.
However, that's NOT the only use of "+to infinitive". The "+to infinitive" can be used in many other ways too. For instance, one way is to use it after adverbs.
I was tired enough to fall asleep as soon as I hit the bed. - This means that I was so tired that I fell asleep as soon as I hit the bed; it does not mean that I became tired with the intention fall asleep.
This is the exact same usage that you find in the correct sentence as well. You can read more about the general use of "+to infinitive" at http://www.ef.com/english-resources/english-grammar/infinitive/. However, I would not recommend going overboard in your research. Also, not all usages maybe tested on the GMAT.
Cheers!
