IMO A.

To me, None of the options makes sense...

Talking in GMAT terms,

A,B and C are out because of "there are" ...
D is out because of missing verb in the subordinate clause ...(INTERFERING)
E is out because of (AND can interfere)


I'm not sure if I'm missing something here...

Hi Ashwani,

IMO "there are" is not wrong in GMAT. Please see the question#107 of OG-10. The correct option is "E". And that is the only option that contains "there are".

Or there is some specific pattern in the above question under discussion that is not liked by GMAT ?

Folks

I see only A makes sense and others are not complete sentences.

What does the magnetic field do?

A because none other option maintains that parallelism..
"announced that... and that this action..." should be there
According to Manhattan SC "that" parallelism should be maintained...
So we can eliminate B,C, D and E.

Choice A

B) of that type, refers singular, when should be plural with magnetic fields

C) of which type there is awkward

D) 200,000 of which type exist awkward

E) 200,000 of that type existing , what type?... security surveillance system or magnetic fields?
