Active underwater faults are observed carefully, tectonophysicists monitor the physical processes that underlie tectonic formation to predict the movements of the Earth’s crust.

A. carefully, tectonophysicists monitor the physical processes that underlie tectonic formation to predict the movements of the Earth’s crust

B. carefully, whereas tectonophysicists monitor the physical processes that underlie tectonic formation to predict the Earth’s crust’s movements

C. carefully; the physical processes that underlie tectonic formation are monitored by tectonophysicists so that they can predict the movements of the Earth’s crust

D. carefully; tectonophysicists monitor the physical processes that underlie tectonic formation to predict the movements of the Earth’s crust

E. by tectonophysicists who carefully monitor the physical processes that underlie tectonic formation to predict when the movement of the Earth’s crust occurs

Dear GMATGuruNY

In the OA choice D, does the phrase 'to predict the movements of the Earth’s crust reflect' as if the 'processes predict the movements'?

In the following OG2018

Quote:
The United Parcel Service plans to convert its more than 2,000 gasoline-powered trucks in the Los Angeles area to run on cleaner-burning natural gas.


(A) to convert its more than 2,000 gasoline-powered trucks in the Los Angeles area to

(B) to convert its more than 2,000 trucks in the Los Angeles area that are powered by gasoline to

(C) on converting its more than 2,000 gasoline-powered trucks in the Los Angeles area that will

(D) for its more than 2,000 gasoline-powered trucks in the Los Angeles area to convert to

(E) that its more than 2,000 trucks in the Los Angeles area that are powered by gasoline will convert to

In choice B, 'to run on cleaner-burning natural gas' sound if 'trucks are power to run on...'

So can't question be at hand treated same logic?

Generally, an infinitive modifier following a clause serves to express INTENT.

B in the second SC:
The United Parcel Service plans to convert its trucks that are powered by gasoline to run...
Here, the trucks are not performing an action.
The usage of a passive verb -- are powered -- implies that someone DESIGNED the gasoline-powered trucks.
As a result, a reader might logically construe that the infinitive modifier in red expresses the intent of the TRUCK DESIGNER -- that the trucks ARE POWERED because their designer intended them TO RUN in a particular way.
The intended meaning of the original sentence is that the UNITED PARCEL SERVICE intends the trucks to run in a particular way.
Since both interpretations are logical, eliminate B.

D in the Veritas SC:
Tectonophysicists monitor the physical processes that underlie tectonic formation to predict the movements of the Earth’s crust.
Here, physical processes cannot have an intent.
As a result, only one interpretation is possible: the infinitive modifier in green must express the intent of the tectonophysicists.

Thanks a lot GMATGuruNY for the great explanation

"underlie tectonic formation to predict the movements"
This sounds awkward to me. Does is sound awkward to anyone else ?

Hi mikemcgarry

It might sound like a very basic question but how is the clause " Active underwater faults are observed carefully " independent ? Observed by whom ? Is it because it is in passive voice, we don't really need a subject to make the clause independent ?

Hello Namangupta1997,

We hope this finds you well.

To answer your query, the requirement for a clause to be considered independent is that it must have an independent noun that is acted upon by an active verb to form a complete thought; in " Active underwater faults are observed carefully ", the noun is "faults", the independent verb is "are observed", and in acting upon this noun, the verb conveys a complete thought, even if it does not identify who is doing the observing. Thus, this clause is independent.

We hope this helps.
All the best!
