between B and D.(ll to original structure)

Orignal setence says "changing the measured strain" -->warning singn

B little distortion to thethe original meaning.
"changing measurements of the strain across" -- warning sign
--> chaning measurements -- warning sign

D -- changes in "measured strain"

D better than B.

Any other reasoning..????

OA is D.

This SC i stesting for IIlism.
Geologists believe that the warning signs for a major earthquake may include A,B,C and D

Geologists believe that the warning signs for a major earthquake may include
-sudden fluctuations in local seismic activity,
-tilting and other deformations of the Earth's crust,
-changes in the measured strain across a faultzone, and
-variations in the electrical properties of underground rocks

A. changing the measured strain across a fault zone, and varying -> eliminate since this is not in parallel with sudden fluctuations

B. changing measurements of the strain across afault zone, and varying -> eliminate

C. changing the strain as measured across a faultzone, and variations of -> eliminate

D. changes in the measured strain across a faultzone, and variations in -> BEST IMO (D)

E. changes in measurements of the strain across a fault zone, and variations among -> eliminate due to variations among which suggests preexistant variations and not the one which acts as indicator of quake.


Why isn't A correct? It is parallel to "tilting and other deformations of the Earth's crust"

(A) is incorrect since sudden fluctuations in local seismic activity, tilting and other deformations of the Earth's crust is to be viewed as a single clause and here tilting goes with seismic activity .We need to look for parallelism between fluctuations and changes .Hence (D) is perfect

I have to admit this one got me, but I now, I get it! The take-away here is to look for parallelism in parts of speech. With the "ing", it can be a verb or a noun. Once you figure it is a noun, all the others in the series have to also be a noun. Great question

D It is.

Geologists believe that the warning signs for a major earthquake may include j, k, l, and m. These j, k, l, m are the items in a list of a warning signs. Hence needs to be parallel.

The first two items are in the form of Adjectival Phrases 1) sudden fluctuations..... 2)tilting ...... of the earth's crust.
So to take care of parallelism remaining two items also need to be in the form of Adjectival phrase.

A) INCORRECT :- changing and varying are verbs, which can not parallel to phrases

B) INCORRECT :- varying is verb, which can not parallel to phrase. Also Change is in the strain and not in the measurements.

C) INCORRECT :- changing is verb, which can not parallel to phrase.

D) CORRECT :- This choice makes the remaining two signs parallel to previous signs. changes...... variations.....

E) INCORRECT :- changes are in the strain and not in the measurements.

Hope That Helps!
