A for me


A. of which type there are 200,000 worldwide, can interfere with pacemakers and that
B. of which, worldwide, there are 200,000 of that type, and which can interfere with pacemakers, and -> awkward construction
C. of which type there are 200,000 worldwide, they can interfere with pacemakers and
D. 200,000 of which type exist worldwide, interfering with pacemakers, and
E. 200,000 of that type existing worldwide and can interfere with pacemakers, and

Good one!

A. of which type there are 200,000 worldwide, can interfere with pacemakers and that
B. of which, worldwide, there are 200,000 of that type, and which can interfere with pacemakers, and [ of which and that type – redundant + “which” incorrectly modifies type – eliminate it]
C. of which type there are 200,000 worldwide, they can interfere with pacemakers and [“they” can not refer to Singular manufacturer’s security surveillance system – eliminate it]
D. 200,000 of which type exist worldwide, interfering with pacemakers, and [ 200,000 of which type is awkward + interfering and can bring is not parallel to can bring – eliminate it]
E. 200,000 of that type existing worldwide and can interfere with pacemakers, and [“and” incorrectly coordinates with main clause – eliminate it]

Lets eliminate Wrong options .A is good but ;lets explore for a better option

B ->of which and of that are redundant -> ELIMINATE
C->they can is wrong since does not continue the previous sentence
D->interfering is not paralel with interaction can
E->too many ands is never good .Also existing worldwide and can interfere is not correct
A -> is perfect

IMO A

Indeed a good Question would love to review this one...

Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system,of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.

A. of which type there are 200,000 worldwide, can interfere with pacemakers and that - Correct

B. of which, worldwide , there are 200,000 of that type, and which can interfere with pacemakers, and - Incorrect

C. of which type there are 200,000 worldwide, they can interfere with pacemakers and - Incorrect

D. 200,000 of which type exist worldwide, interfering with pacemakers, and - Incorrect

E. 200,000 of that type existing worldwide and can interfere with pacemakers, and - Incorrect

Hence IMHO (A) is the best...

The quick fix for this question is that the Researchers announce two things, which are best expressed parallelly in relative clauses that start with ‘that’. Therefore, we require another that after the conjunction ‘and’. A cursory glance at the end of the choices reveals that only choice A sticks to this norm. Hence A; of course there may be other errors too in the wrong choices.
But on the D-day, this much might be good enough for some with time pressure.

Hi,
Just one ERROR which can eliminate all wrong choices is VERB of main clause..
" Researchers have announced that the magnetic field emitted by one brand of security surveillance system" requires a VERB, which is there ONLY in A - CAN..

whenever you are looking at such long sentences, always look if your Subject has a VERB by hiding everything else..
lets see C
Researchers have announced that the magnetic field emitted by one brand of security surveillance system, of which type there are 200.000 worldwide, they can interfere with pacemakers and this interaction can bring on missed or irregular heartbeats,nausea and even fainting. ---- NO verb

Parallelism issue; Researchers have announced THAT the magnetic fields....and THAT.

Only A does that.

Well i would apply the parallelism technique as explained by GMATNinja ,

First lets see if there is any parallelism trigger such as or,but, and (its the most common seen on the GMAT)

Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.

As we could see from the above sentence their is the "and" word.

Now we need to check the Stem of the sentence which is "Researchers have announced" .

Lets construct the sentences before the parallelism trigger and after the parallelism trigger and compare:

Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers --(1)

Researchers have announced that this interaction(Magnetic fields with the pacemaker) can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting. --(2)


The only option that makes sense is Option A.

Hope the above explanation helps.

If your new to the whole parallelism concept or want to get a better picture of the following concept please refer to the below video link which i found immensely useful:
