Can someone from egmat or Magoosh mikemcgarry help with my query below?

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!

E is the correct answer.

Hi ss18

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! :)

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 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?


As per the meaning of the sentence affect should be parallel to induce. Only option E does this correctly and precisely.

I totally agree with you and I also would like to hear an explanation from an expert.
Thanks.
