I need help to identify independent clauses. I am confused as to how to identify independent clause and dependent clause.

Can anyone help me with some rules?

If each clause stand on its own and give meaning then we say as IC.

If you plugin Option B on the given statement

According to a recent study, Earth's magnetic north pole is moving away from Alaska and toward Siberia so rapidly, within 50 years, people may be able to see the swirling green auroras of the Northern Lights in cities as far south as Rome and is located at 41º north latitude.

Earth's magnetic north pole is moving away from Alaska and toward Siberia so rapidly - Independent statement.
people may be able to see the swirling green auroras of the Northern Lights in cities as far south as Rome - Independent statement.

If we want to connect two IC it should be followed by comma and FANBOYS or it should be followed by semicolon.

If two IC are there in a statement without the above stated rule we call them as RUNON statement.

Ram is a good student, he is studying in Cambridge --> Incorrect.
Ram is a good student, And he is studying in Cambridge --> Correct.
Ram is a good student; He is studying in Cambridge --> Correct.

Hope this helps.

Dear smanujahrc,

I'm happy to respond.

Does all this make sense?

Firstly, keep in mind the underlining issue pointed out in an earlier post. Now, option E reads:

visible by people in cities far to the south; such as Rome, located at 41º north latitude

1. A to after visible would be appropriate (visible to people).
2. After the semicolon, we have such as Rome, located.... We would normally expect a clause (after a semicolon).

(A) rapidly, within 50 years, that the swirling green auroras of the Northern Lights might be visible in cities as far south as Rome, which is

(B) rapidly, within 50 years, people may be able to see the swirling green auroras of the Northern Lights in cities as far south as Rome and

(C) rapidly that, within 50 years, the swirling green auroras of the Northern Lights may be visible from cities as far south as Rome,

(D) rapidly such that, within 50 years, people might be able to see the swirling green auroras of the Northern Lights from cities as far south as Rome, and

(E) rapidly that, within 50 years, the swirling green auroras of the Northern Lights might be visible by people in cities far to the south; such as Rome,

OFFICIAL EXPLANATION

This sentence reports the striking findings of a research study: Earth's magnetic north pole is moving so fast that the Northern Lights may be visible from new locations within 50 years. The modifier within 50 years describes something that will happen in the future, so it cannot be referring to the fact that the north pole is (now) moving in a certain way. Rather, it must describe the study's conclusion that the Northern Lights will be visible from other locations in future.

(A) The modifier within 50 years illogically describes the present movement of Earth's magnetic north pole rather than the predicted future outcome.

(B) In this sentence, Earth’s ... rapidly and people ... latitude are both complete sentences, creating two problems. First, the overall construction is a run-on sentence, containing no conjunction to properly connect the two sentences. Second, the placement of within 50 years between the two clauses makes it unclear what that phrase is intended to describe. Finally, the use of and at the end of this choice makes the meaning redundant, since "as far south as Rome" and "at the same latitude as Rome" are identical concepts.

(C) CORRECT. In this sentence, within 50 years is properly used to describe what will happen in the future. As far south as Rome is idiomatically correct, and the final modifier correctly describes Rome.

(D) The combination of so and such is redundant and unidiomatic. The use of and at the end of this choice makes the meaning redundant, since "as far south as Rome" and "at the same latitude as Rome" are identical concepts.

(E) The construction visible by people is unidiomatic and should be phrased as visible to people. The part of this sentence following the semicolon is a modifier, not a complete sentence (independent clause), thus creating a sentence fragment.

Hi All,

Can someone please help!! In option "C", 'which' is not present - looks like which is modifying the whole preceding clause (,+which structure) whereas In option "A", 'which' is obviously modifying Rome.
How C is correct then. Please let me know loopholes in my understanding if any.

Thanks,

Hello everyone I have a query here. In the option C verb-ed after comma modified green aurora or Rome. Can someone explain how verb-ing and verb-ed modifiers work after comma. Have a trouble resolving those questions. I was going to pick C but picked A which I did not like.

According to a recent study, Earth's magnetic north pole is moving awa [#permalink]
Correct option : C

Sentence Exam on :
1. Modifier
2. Ueage of "THAT" and "(,which)"

(That) is used to indicate a specific object, item, person, condition, etc. it indicates restrictive clause.

(,which) is used to add information to objects, items, people, situations, etc it indicates a non-restrictive (optional, if removed, still the sentence meaning will be intact) clause, it is usually set off by commas before "which" and at the end of the clause

According to a recent study,
Earth's magnetic north pole is moving away from Alaska and toward Siberia
so rapidly that, within 50 years, the swirling green auroras of the Northern Lights may be visible
from cities as far south as Rome,
located at 41º north latitude.

here, modifier are,
1. range from cities as far south as Rome - located at 41º north latitude
2. within 50 years - the swirling green auroras of the Northern Lights
