According to scientists who monitored its path, an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, which brightened 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 storm 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 storm in the magnetic field that surrounds Earth, and it brightened the Northern Lights and also possibly knocked

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

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

(E) a large storm in the magnetic field surrounding Earth was recently triggered by an expanding cloud of energized particles, brightening the Northern Lights and it possibly knocked

https://www.nytimes.com/1997/01/23/us/researchers-get-first-detailed-look-at-magnetic-cloud-from-sun.html

An international group of space scientists said that on Jan. 6 the Sun ejected a pocket of mass from its corona that developed into a giant, tube-shaped magnetic bubble 30 million miles in diameter that hit Earth almost four days later. The expanding cloud of energized particles triggered a large storm in the magnetic field, or magnetosphere, surrounding the planet. The storm brightened the Northern Lights and possibly knocked out a communications satellite.

First off, we need to identify whether the scientists are tracking the expanding cloud or the storm. The original sentence clearly indicates that the magnetic field is in the Earth. Therefore, it is the 'expanding cloud...' so we can eliminate (D) and (E). Next we can eliminate (A) because the 'which' incorrectly modifies 'Earth.' The 'it' in (B) is ambiguous. Therefore the answer is (C).

Tough call

whenever you see such complex questions AND a modifier is at the beginning of the same, the first thing to think is twofold: attack even aggressive the question and try to figure out the subject of the sentence, what is the critical point of the same. Moreover, is important to figure out the first words of the underlined part at the beginning or at the end to see a split (even the most difficult question have a split, even a single word, no matter what)

Now, we start with According to scientists who monitored its path: to make things simple i see a path, a path of who or whom VS a path of that or which; here the subject is a cloud VS a storm, bot are possible in this scenario in terms of path

D and E ant the end have and it but here i do not see something in terms of antecedent of it: both particles and Lights do not agree, so out.

A B C

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

here which is incorrect because it refers to earth but this is impossible that brightened the Northern Lights: has no logical sense. The tenses are not parallel too

an expanding cloud of energized particles ejected from the Sun was what recently triggered a large storm in the magnetic field that surrounds earth, and it brightened the Northern Lights and also possibly knocked

Both bold parts are clearly wrong

we have now C

an expanding cloud (subject) of energized particles ejected from the Sun recently triggered (verb) a large storm in the magnetic field that surrounds earth, brightening the Northern Lights and possibly knocking (the right subordinated clause)

This is more or less the process to tackle the most difficult SC. No matter what. The patterns followed by the exam are not infinite.

Regards. +1 nice question, really.

The opening modifier should correctly modify the,following portion.
"According to scientists who monitored its path","Its" should properly refer to "an expanding cloud of energized particles ejected from the Sun".So that leaves out with choice (A),(B) and (C).

(A) has -ism problem at the end of the sentence between "brightened" and "knocking"
(B) "it brightened the Northern Lights" It does not have proper antecedent.
(C)Proper -ism rule maintained

The problem is the ambiguous pronoun -It-, with many suitors. The key is to get rid of it. As per that, we can safely eliminate B, D. and E. Between A and C, it wouldn’t take much to say no to A for the very blatant touch - rule error, leaving C with good //ism and without pronoun hitch.

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
--> NONPARALLEL

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
-->illogical sentence

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
--> CORRECT

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
--> nonparallel/passive

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
--> passive+not parallel

will go with C

(C) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds

Again people have knocked off B for IT- is ambiguous , I m sry but i don't agree... (it is is parallel and correctly pointing to sub of previous IC)

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

When We say IC, and IC -> that means both are independent....

I was shocked to see my GF with stranger in the restaurant ,and I fainted on my dinning table.

This means I was not fainted because I saw them...the reason might be something else...

In B we are providing a result so 'comma+ and' is wrong

In C we are providing V-ing which provides the result of first clause ...So C correct

Hi anilisanil,

Lets tale your doubt. As per your doubt, if I understood it correctly, Storm could be the Subject of the Sentence. Right. So,lets analyze the following:

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

Couple of Problems Here. First "Triggered" is modifying Earth, which is clearly not the Intended Meaning. Secondly, when you have two independent clauses, it must use FANBOYS and COMMA. Comma is missing here. Hence, this option is incorrect.

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
Again, Comma +Fanboys problem is still here. Moreover, this choice is PASSIVE, and is not parallel.

Even if you consider the subject to be Storm, the relevant choices still have some blatant errors. Hence, you have to go for other choices. So, if you are not able to find the subject, I would suggest you to move on to choices and see if those can be ruled out. Had the Choice E been perfectly parallel, but it is in passive voice, I would still refrain myself from marking this as Answer choice. The reason is beacuse of its Passive Nature. You already have a better answer available. Right, so why would you go for something inferior.

According to scientists who monitored its path ==>now whose path scientists are monitoring...
it can be expanding cloud or a large storm....so basis this split we cannot eliminate any choice.

A : an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds earth, which brightened the Northern Lights and also possibly knocking
WRONG.
--use of WHICH is wrong.....WHICH is incorrectly referring to EARTH.
--AND ALSO => Together they are redundant.

B : an expanding cloud of energized particles ejected from the Sun was what recently triggered a large storm in the magnetic field that surrounds earth, and it brightened the Northern Lights and also possibly knocked
WRONG.
--AND ALSO => Together they are redundant.
--WHAT RECENTLY=>making sentence unnecessary wordy.
--use of CLAUSE it brightened the northern lights ==> meaning = expanding cloud brightened the northern lights...BUT this is not the intended meaning.....incorrect.

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

D : a large storm in the magnetic field that surrounds Earth, recently triggered by an expanding cloud of energized particles, brightened the Northern Lights and it possibly knocked
WRONG.
----brightened and it possibly knocked are not parallel.
----use of IT is redundant.

E : a large storm in the magnetic field surrounding Earth was recently triggered by an expanding cloud of energized particles, brightening the Northern Lights and it possibly knocked
WRONG.
--USE OF IT is wrong .
--brightening and it possibly knocked are not parallel.

hence C

When facing tough question such as this, the easier method will be to fall back on small grammar snippets to eliminate as many wrong choices as possible first; In this case, we can eliminate A and E because, we can see the mismatch of parallelism easily; second we can eliminate B because it uses ‘and also’, a redundant expression. This leaves us with C and D; At a higher level of parallelism, we should avoid the use of the subject or its pronoun in the second arm, if it happens to be same as the subject of first arm; using “it" is said to be redundant in such cases. If the pronoun’s reference is in doubt, then that choice is fit to be dropped. We can eliminate D, and end up with C as the correct choice. This may not be a panacea for situations, but at least a handy tool

I feel in option C the word " brightening" is modifying earth which is wrong. Can someone please point out where i am going wrong, and also what is the function of brightening in that sentence.

Hello Jagwant01,

I am not sure if your doubt still persists. Here is the explanation nonetheless.

In Choice C, both brightening... and knocking... are modifiers that are placed after a clause and are preceded by a comma. Hence, they are comma + verb-ing modifiers that modify the action in the preceding clause.

Per the context of the sentence, brightening... and knocking... correctly modify the preceding action triggered. The sentence intends to say that an expanding clause triggered a large storm. This action led to two events. It brightened the Northern Lights and probably knocked out a communication satellite.

Now, the verb-ing modifiers that are not preceded by a comma act as noun modifiers and modify the preceding noun.

Hope this helps.
Thanks.

We need the main subject " an expanding cloud" after comma. So D and E are out.

In A, "which" is wrongly modifying "Earth", and also "it" is ambiguous".

B also has modifying issues.

1. The scientists are monitoring the path (its path) of a cloud of energized particles ejected by the Sun -- The pronoun 'its' should refer to the subject of the clause namely, -the cloud-. The cloud is also the nearest noun to the pronoun.

2. As per modification rule, the modified term should be first mentioned immediately after the modifier

3. The storm is the object of the verb triggered. We can't expect a pronoun to jump over the subject to refer to the object.

Hello Everyone!

Let's tackle this question, one issue at a time, to find the correct choice! Before we dive in, here is the original question with any major differences between the options highlighted in orange:

According to scientists who monitored its path, an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, which brightened 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 storm 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 storm in the magnetic field that surrounds Earth, and it brightened the Northern Lights and also possibly knocked
(C) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, brightening the Northern Lights and possibly knocking
(D) a large storm in the magnetic field that surrounds Earth, recently triggered by an expanding cloud of energized particles, brightened the Northern Lights and it possibly knocked
(E) a large storm in the magnetic field surrounding Earth was recently triggered by an expanding cloud of energized particles, brightening the Northern Lights and it possibly knocked

After a quick glance over the options, there are 2 main things we can focus on:

1. Modifiers (Are the scientists monitoring the cloud or the storm?)
2. Parallelism (brightened/brightening & knocked/knocking)

Let's start with #1 on our list: modifiers! We have to ask ourselves a couple questions to determine what order the modifiers should be in:

WHAT were the scientists monitoring?
and
WHAT brightened the Northern Lights and possibly knocked out a communications satellite?

We can tell by reading the sentence carefully that the scientists were monitoring THE CLOUD. This means the modifier "According to scientists who monitored its path" needs to come directly before the storm, which is what it's referring to! Let's see which options handle this correctly, and rule out those that don't:

(A) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm 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 storm in the magnetic field that surrounds Earth, and it brightened the Northern Lights and also possibly knocked
(C) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, brightening the Northern Lights and possibly knocking
(D) a large storm in the magnetic field that surrounds Earth, recently triggered by an expanding cloud of energized particles, brightened the Northern Lights and it possibly knocked
(E) a large storm in the magnetic field surrounding Earth was recently triggered by an expanding cloud of energized particles, brightening the Northern Lights and it possibly knocked

We can rule out options D & E because they don't put the modifier next to what it's modifying.

Now that we're left with only 3 options, let's move on to #2 on our list: parallelism. There are two things that happened as a result of the large storm in Earth's magnetic field: the Northern Lights were brighter, and it possibly knocked out a communications satellite. These two need to be written using parallel structure! Let's see which ones do, and rule out those that don't:

(A) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, which brightened the Northern Lights and also possibly knocking --> NOT PARALLEL
(B) an expanding cloud of energized particles ejected from the Sun was what recently triggered a large storm in the magnetic field that surrounds Earth, and it brightened the Northern Lights and also possibly knocked --> NOT PARALLEL
(C) an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, brightening the Northern Lights and possibly knocking --> PARALLEL

There you go - option C is the correct choice! It places the modifier next to what it's modifying, and it uses parallel structure for both effects at the end!
