Scientists who monitored its path OG13

Post Thu Apr 05, 2012 2:53 am
Hi

I would like to answer this question under 1 minute, but took 2 mins can someone show me any quick way to get to the right answer as quickly as possible...thx

According to scientists who monitored its path, an expanding cloud of energized particles ejected from the Sun recently triggered a large strom in the magnetic field that surrounds Earth, which brigthened the Northern Lights and also possibly knocking out a communications satellite

A. an expanding cloud of energized particles ejected from the Sun recently triggered a large strom in the magnetic field that surrounds Earth, which brightened the Northern Lights and also possibly knocking

B.an expanding cloud of energized particles ejected from the Sun was what recently triggered a large strom in the magnetic field that surrounds Earth, and it the brigthened the Northern Lights and also possibly knocked

C.an expanding cloud of energized particles ejected from the Sun recently triggered a large strom in the magnetic field that surrounds Earth, brightening the Northern Lights and also possibly knocking

D. a large storm in the magnetic field that surrounds Earth, recently triggered by an expanding cloud of energized particles, brigthened the Northern Lights and it possibly knocked

E. a large storm in the magnetic field that surrounds Earth was recently triggered by an expanding cloud of energized particles, brigthening the Northern Lights and it possibly knocked

IMO: C

D/E - Passive
A- which is wrong
B- ambiguous

Yes the correct answer is C.

option A: Modifier error - 'which brightened' wrongly modifies the Earth and changes the meaning


Option B: 'was what recently triggered' unnecessary and also pronoun 'it' creates ambiguity.

Options D and E are completely out of scope as the scientists were tracking the cloud and not the strom.


Option C is the best answer choice.

COMMA+DOING can modify the previous clause. If there are 2 previous clauses, COMMA+DOING can modify either of 2 clauses, the near clause or far clause, . The context will tell us which clause the COMMA+DOING modifies.

without knowing the above thing, we can go to C. HOwever, it take me a long time to infer the intended meaning when reading only original sentence without looking at answer choices. I get it right but the time is 2.30 minites.

Should a modifier like ", recently triggered by .." always modify Earth and NOT the storm - the subject of the sentence: "a large storm in the magnetic field that surrounds Earth, recently triggered by an ..."
Please clarify if it'd alws be true of a participle modifier to modify the noun touching it and not the subject or the verb/action?

e.g. Resigned to the bad news, the office workers made no commotion - CORRECT
The office workers made no commotion, resigned to the bad news - IS IT grammatically incorrect? Is "resigned to the bad news" modifier not modifying workers and not commotion?

There's one more example:
Using the latest technology, the engineer identified the problem. CORRECT
The engineer identified the problem, using the latest technology. CORRECT (here problem is not using the technology)

Please clarify why these examples are different from the sentence in option D in terms of the modifiers.

thank you

D/E - brigthened the Northern Lights and it possibly knocked . They are not parallel; The 2nd part is an independent clause "it possibly knocked" - we require a COMMA before AND

will go with C

OA??
I eliminated D and E based on parallelism and meaning but I would like to know what makes the sentences passive. How do you find passive constructions ?

PART IN RED--> PASSIVE
PART IN BLUE--> NON PARALLEL

A. modifier error; it's not the Earth that brightened...

B. "was what triggered" is wordy

C. parallel and correct

D. it's not Earth that was "recently triggered," and it's also unclear what "it" refers to

E. "brightening" and "knocked" are not parallel
