Signals from a cochlear implant are recognized as sound when the brain receives signals directly from the cochlear implant that generates them by stimulating the auditory nerve, implanted directly into the brain.

A. Signals from a cochlear implant are recognized as sound when the brain receives signals directly from the cochlear implant that generates them by stimulating the auditory nerve, implanted directly into the brain.

B. Signals recognized as sound by the brain are sent directly to it by the cochlear implant, which stimulates the auditory nerve and generates electrical signals, implanted directly into the brain.

C. Implanted directly into the brain, the cochlear implant stimulates the auditory nerve, generates electrical signals, and sends the signals directly to the brain, which recognizes them as sound.

D. The cochlear implant stimulates the auditory nerve, implanted directly into the brain, generates electrical signals, and sends the signals directly to the brain, which recognizes them as sound.

E. The cochlear implant, implanted directly into the brain, stimulates the auditory nerve and generates electrical signals, which are then sent directly to the brain to be recognized as a sound.

Please read the rule of posting on forum. POE is right way to attempt any question in Gmat if you are looking for any score more then even 600. Its very important that you know why any option is wrong rather than finding a right answer specially in one word.

Signals from a cochlear implant are recognized as sound when the brain receives signals directly from the cochlear implant that generates them by stimulating the auditory nerve, implanted directly into the brain.

A. Signals from a cochlear implant are recognized as sound when the brain receives signals directly from the cochlear implant that generates them by stimulating the auditory nerve, implanted directly into the brain - WRONG modification, it means auditory nerve is implanted into the brain

B. Signals recognized as sound by the brain are sent directly to it by the cochlear implant, which stimulates the auditory nerve and generates electrical signals, implanted directly into the brain - WRONG modification, it means electrical signals are directly implanted into the brain

C. Implanted directly into the brain, the cochlear implant stimulates the auditory nerve, generates electrical signals, and sends the signals directly to the brain, which recognizes them as sound - CORRECT modification, cochlear implant is implanted directly into brain.

D. The cochlear implant stimulates the auditory nerve, implanted directly into the brain, generates electrical signals, and sends the signals directly to the brain, which recognizes them as sound. - Same as A, WRONG modification

E. The cochlear implant, implanted directly into the brain, stimulates the auditory nerve and generates electrical signals, which are then sent directly to the brain to be recognized as a sound. - Correct modification, but "to be recognize" is wrong and wordy when compared with option C

(C) is best

If I am not mistaken the original sentence does not talk about electrical signal

Hey!

Doesn't the word "them" refer to something plural in C ?
Whereas the "cochlear plant" is singular. Isn't it ?
Why is it not E ?

Please help.

"them" refers to "signals", which is plural.

You can also think about the meaning. Implants are not sent to the brain, signals are. The pronoun should logically refer to signals.

Generally, a COMMA + VERBed modifier should serve to refer to the nearest preceding noun or noun phrase.

A and D: the auditory nerve, implanted directly into the brain
Here, COMMA + implanted seems to refer to the auditory nerve, implying that THE AUDITORY NERVE is IMPLANTED directly into the brain.
This meaning is nonsensical.
Eliminate A and D.

B: electrical signals, implanted directly into the brain
Here, COMMA + implanted seems to refer to electrical signals, implying that ELECTRICAL SIGNALS are IMPLANTED directly into the brain.
Not the intended meaning.
The intended meaning is that THE COCHLEAR IMPLANT is implanted directly into the brain.
Eliminate B.

An OA from GMAC:
A recently discovered chalice was probably buried to keep it from being stolen.
Here, the main verb -- was buried -- is passive.
The agent of this action -- in other words, whoever buried the chalice -- is unknown.
The infinitive modifier in blue serves express the INTENT of this unknown agent.
Conveyed meaning:
Whoever buried the chalice INTENDED to keep it from being stolen.

E: signals, which are then sent directly to the brain to be recognized as a sound
Here, the verb in the which-clause (are sent) is passive.
The agent of this action is the IMPLANT, since the implant sends signals to the brain.
As a result, the infinitive modifier in red seems to express the INTENT of the implant.
This meaning is nonsensical: an implant cannot have intent.
Eliminate E.

About E:

I took notes from a correct SC answer that looked like this: “She was elected to be the second woman in the state to serve on the state bench”

In this case "to be" was correct because it emphasized the purpose. But wouldn't this conflict with your explanation because "she" isn't the agent of the action. She doesn't elect someone, but she gets elected.

Can you please explain?

Can you please explain?

The agent of an action is whoever or whatever PERFORMS the action.

She was elected to be the second woman in the state to serve on the state bench.
Here, the act of electing is performed not by the subject (she) but by the VOTERS.
Thus, the VOTERS are the agent of the passive action in blue.
The infinitive modifier in green logically expresses the intent of these voters (the agent of the passive action).
Conveyed meaning:
When the voters elected her, they INTENDED her TO BE the second woman in the state to serve on the state bench.

A is very repetitive, this suggests that it is not a good choice. B is wrong because it implies that the electric signals are implanted into the brain. C seems correct. D again messes up the order of words, ‘implanted directly…’ modifies ‘auditory nerve’, implying that the nerve is implanted. E is correct but ‘to be recognized’ is a little awkward and wordy. C is the better option.
