air, and the strange electromagnetic signals detected hours before the temblor.

In option A The strange electromagnetic signala detected hours before the temblor
is not a independent clause.

so does it not lack parallelism ?

a the sentence is parallel

the unexpected power....the upward thrust....the strange signals

all have an article, an adjective and a noun

the unexpected power of the seismic waves-->Complete sentence
the upward thrust that threw one man straight into the air--> comeplete sentence
(and) the strange electromagnetic signals detected hours before the temblor.(i feel this is not complete the word THAT is missing here )

Am i missing some thing?

Since a colon is used any information after the colon does not have to be a complete sentence. Also, "The unexpected power of the seismic waves" is not a complete sentence

A verb is not present.
The = article
upward = adjective
thrust = noun (subject)
of the seismic waves = prepositional phrase

A it is....

coz of parallelism...."the unexpected power...., the upward thrust that..., and the strange electromagnetic signals....."

all other options are problematic.

The colon (:) signals an enumeration of the earthquakes' mysteries. Only A makes a simple and parallel enumeration.

Answer: A

After the colon we have a noun phrase( the unexpected power of the seismic waves),a clause( the upward thrust that threw one man straight into the air) and another noun phrase(, and the strange electromagnetic signals detected hours before the temblor).How can these be parallel?Please Help

The second fragment is not a clause. In "thrust that threw" (note that it is not "thrust threw"), "threw" doesn't function as a verb. Read it as "the X thrust" where X provides info. about that thrust.

Some of the earthquake's mysteries are described in a series of three correctly parallel elements: (1) the unexpected power..., (2) the upward thrust..., (3) the strange electromagnetic signals ... Each of the three elements begins with an article (the), a modifier, and a noun. This parallelism is crucial, but each mystery is allowed the further modification most appropriate to it, whether a prepositional phrase (1), a clause (2), or a participial phrase (3).

Why B is wrong. "The" is omitted before the strange. The verb were detected makes the last element not parallel to the previous two.

(E) one man who was thrown straight into the air by the upward thrust, and strange electromagnetic signals that were detected hours before the temblor




the upward thrust..... and the strange electromagnetic


D and E are out

C is not parallel with the thrust

B eliminated "THE" and needs a "that" too

wee go with A

A is correct.

All elements are parallel which is neither in all 4 choices.

SPLIT1) PARALLELISM "THE UNEXPECTED", "THE UPWARD", "THE STRANGE". B,C,D,AND E ARE OUT.

SPLIT2) ANY INFORMATION AFTER A COLON DOES NOT HAVE TO BE A COMPLETE SENTENCE.

SPLIT3) THE PARALLELISM RULE EXPAND TO THE WORD AFTER THE MODIFIER WORD SUCH AS IN THIS EXAMPLE: ARTICLE + MODIFIER + NOUN => THE UNEXPECTED POWER, THE UPWARD THRUST, THE STRANGE ELECTROMAGNETIC SIGNALS.

(A) the upward thrust that threw one man straight into the air, and the strange electromagnetic signals detected hours before the temblor - Correct
(B) the upward thrust that threw one man straight into the air, and strange electromagnetic signals were detected hours before the temblor - Parallelism issue - strange electromagnetic signal is clause whereas the other two entities are noun phrases
(C) the upward thrust threw one man straight into the air, and hours before the temblor strange electromagnetic signals were detected - Parallelism issue
(D) one man was thrown straight into the air by the upward thrust, and hours before the temblor strange electromagnetic signals were detected - Parallelism issue and distorts the meaning - Seismologists are investigating one man
(E) one man who was thrown straight into the air by the upward thrust, and strange electromagnetic signals that were detected hours before the temblor - distorts the meaning - Seismologists are investigating one man

Answer A

A is Correct - This sentence correctly provides a parallel series of three mysteries.
