Hi sir,
It may seem silly question. Sorry for troubling you.
If in B "home of" were to become "home to", would the sentence be correct ?
thank you.


No question is silly! If you're wondering about something, I can promise that somebody else is, too. So please don't be shy! :-D

Even if you switched "the home of" to "home to", there would still be a problem in (B): "due to" phrases can only modify nouns, not verbs. In this case, "due to global warming" logically modifies "submerged", so it's wrong.

I hope this helps!

5. a vast percentage of the coastline that is currently home to major world cities, by the time the plates have shifted even a few miles, will become entirely submerged because of global warming ---- Altered intent due to wrong word orders. The choice says that the plates will have submerged rather than the cities will have.

i still did not get this..can somebody explain this. I think E should be correct

This sentence seems to be testing everything!
Quote:
1. by the time they had shifted even a few miles, a vast percentage of the coastline which is currently home to major world cities, because of global warming, will have already become entirely submerged

Incorrect use of past perfect. Plus, which is used without a comma. OUT!
Quote:
2. by the time they shift even a few miles, a vast percentage of the coastline, which is currently a home of the major world cities, will have already become entirely submerged due to global warming

'home of' doesn't work really. It should be 'home to'. Plus 'due to' is incorrectly modifying the verb 'submerged'. OUT
Quote:
3. by the time they have shifted even a few miles, a vast percentage of the coastline currently home to major world cities already will have become entirely submerged because of global warming

No grammatical errors. Keep!
Quote:
4. a vast percentage of the coastline that is currently home to major world cities will have already become entirely submerged due to global warming by the time they have shifted even a few miles

This choice illogically says that the coastline would have shifted a few miles. OUT
Quote:
5. a vast percentage of the coastline that is currently home to major world cities, by the time the plates have shifted even a few miles, will become entirely submerged because of global warming

'by....miles' -> I'm not sure about the clause it's modifying. If it's modifying the previous clause, then there seems to be nothing wrong with the sentence though it does change the emphasis of the meaning from the original sentence, as this sentence makes the information presented by 'by....miles' as non-essential.
I'm not sure about E, and C closely resembles the intent of the original sentence. So i'm going to reject E on the basis of uncertainty.

So I'm going to go with C as the answer.

(C) definitely isn't a run-on. By definition, a run-on sentence consists of two independent clauses that aren't appropriately separated by punctuation or a conjunction.

In (C), the sentence begins with an independent clause: "A newly released study on the tectonic plates forming the Pacific basin indicates..." The rest of the sentence is a subordinate clause, beginning with the word "that": "...that by the time they have shifted even a few miles, a vast percentage of the coastline currently home to major world cities already will have become entirely submerged because of global warming."

So grammatically speaking, this is completely fine: just an independent clause with a long subordinate clause.

Check out the excellent explanations by daagh and akshayk above. If you still have specific questions after that, let us know!

Hello, I don't complain about the OA except that in it, the tense form at the beginning seems to be improper.

It says,'by the time they have shifted..................the major cities will have become......'

How correct is this form?

Example of a future perfect usage would be -
Jack will have finished his homework by the time his mother gets home.

Please help!!

A newly released study on the tectonic plates forming the Pacific basin indicates that by the time they had shifted even a few miles, a vast percentage of the coastline which is currently home to major world cities, because of global warming, will have already become entirely submerged.

1. by the time they had shifted even a few miles, a vast percentage of the coastline which is currently home to major world cities, because of global warming, will have already become entirely submerged
2. by the time they shift even a few miles, a vast percentage of the coastline, which is currently a home of the major world cities, will have already become entirely submerged due to global warming
3. by the time they have shifted even a few miles, a vast percentage of the coastline currently home to major world cities already will have become entirely submerged because of global warming
4. a vast percentage of the coastline that is currently home to major world cities will have already become entirely submerged due to global warming by the time they have shifted even a few miles
5. a vast percentage of the coastline that is currently home to major world cities, by the time the plates have shifted even a few miles, will become entirely submerged because of global warming




The OA is C. How is the tense form of the OA correct? .......by the time they have shifted does not connect with the .........will have become........For instance the correct form of future perfect tense is -Jack will have finished his homework by the time his mother gets home. Isn't it?

Plzzzzzz help!!!!

'Already' in the second part modifies the verb 'will have become'.


I may be stupid to understand this issue. I beg your pardon.

According to google search the term 'already' means 'before or by now or the time in question'. From this we may deduce that already can not modify future event.

'Will have become' is a future event. So, how can already modify 'Will have become'?

GMATNinja -Charles, is there an easy way to memorize and figure out difference between due to and because of.
Everytime i see it in a sentence i cannot really tell which one should be used.
Thanks

Mahmud6, check out the last part of that definition: "or the time in question." The word "already" means that something has happened by whatever time we are talking about. So if that time is in the future, it just has to have happened before that future point.

Examples:
By the time I finish reading this book, the sequel will already have come out.
By the time the sun goes supernova, you and I will already be gone.

Nice explanation.
Now, I've got the meaning. Your above two examples are superb in understanding the concept of using 'already' with 'will'.
Thanks.

A newly released study on the tectonic plates forming the Pacific basin indicates that by the time they had shifted even a few miles, a vast percentage of the coastline which is currently home to major world cities, because of global warming, will have already become entirely submerged.

1. by the time they had shifted even a few miles, a vast percentage of the coastline which is currently home to major world cities, because of global warming, will have already become entirely submerged -"had" is wrongly used. A comma is required before which.
2. by the time they shift even a few miles, a vast percentage of the coastline, which is currently a home of the major world cities, will have already become entirely submerged due to global warming -due to is wrongly used.
3. by the time they have shifted even a few miles, a vast percentage of the coastline currently home to major world cities already will have become entirely submerged because of global warming -Correct
4. a vast percentage of the coastline that is currently home to major world cities will have already become entirely submerged due to global warming by the time they have shifted even a few miles -"they" is misplaced pronoun. It might refer back to either cities or plates.
5. a vast percentage of the coastline that is currently home to major world cities, by the time the plates have shifted even a few miles, will become entirely submerged because of global warming -meaning change. information regarding "plates" appears to be unnecessary.

Confused b/w option B and C.

b. by the time they shift even a few miles, a vast percentage of the coastline, which is currently a home of the major world cities, will have already become entirely submerged due to global warming
c. by the time they have shifted even a few miles, a vast percentage of the coastline currently home to major world cities already will have become entirely submerged because of global warming

In option B usage of "shift" will have already become seems correct.
Usage "have shifted" will have become seems incorrect.

For e.g : By the time i buy a new car, my cousin will already have bought two new cars.
By the time I have bought a new car, my cousin will already have bought two new cars.

Will it also be correct to say?
By the time I will have bought a new car, my cousin will already have bought two new cars.

Experts Pl clarify.
Thnx.

Having read all opinion posts within this question post, I still struggle to comprehend the solution.
C is the best, but I also think E is correct.
What is the correct way to proceed with this question? What is the pattern here?

B IMO.
A- wrong tense..by the time they had shifted ....and will have already become...
C- wrong tense , should be simple future. They have shifted indicates- present perfect
D -wrong tense. Doesn't show proper timeline
E- again tense problem.

Can you please tell what's the OA??

Hi GmatNinja,
Sorry for troubling you. I will be obliged if you can help me to understand why option E is wrong. I got why option C is correct, but is having a difficulty to eliminate option E.
E) a vast percentage of the coastline that is currently home to major world cities, by the time the plates have shifted even a few miles, will become entirely submerged because of global warming
here cities will become submerged and not plates as, by the time the plates have shifted even a few miles, are set of by commas, so this looks like non-essential modifier. now, the plates will modify the previous clause- a vast percentage of the coastline that is currently home to major world cities. Plates cant modify the next clause- will become entirely submerged because of global warming because then the clause a vast percentage of the coastline that is currently home to major world cities will modify what? both plates and cities cant modify the same thing- will become entirely submerged because of global warming.
The only reason I find option E to eliminate is that by the time the plates have shifted even a few miles needs to be part of the main sentence and not as a non-essential modifier.
Please help.

I agree with you. You post is quite long, but the last sentence is catchy. In other words, the modifier is essential => eliminate E.

Also, I find that E uses "that is"; this is unnecessary.

Use of future perfect is necessary in this case.

First consider the use of past perfect: When there are references of two interrelated past events (verbs or time references), then the former event should be in past perfect.

By year 2000, I had completed my studies.... correct. (past perfect)
By year 2000, I completed my studies... wrong. (simple past)
In year 1999, I completed my studies.... correct. (simple past)

(Here note that the latter event may not necessarily be a verb and can merely be a time reference , e.g. year 2000 in the above example).

Now with the above idea in mind, examine option E.
By year 2075, the coastline will have become submerged.. correct (future perfect)
By year 2075, the coastline will become submerged.... wrong. (simple future).
In year 2074, the coastline will become submerged.. correct (simple future).

Now you would see why simple future in option E is wrong and future perfect in option C is correct.
