My answer would have been E as well.

I'm certainly not an expert, but my understanding of Past Perfect is that there are two uses:

1. Two ideas that happened in the past, at mutually exclusive points in the past. Which ever happened before the other is associated with 'had'. Example: They had never seen the CN Tower before they moved to Toronto.

2. Two ideas that happened in the past, with the first idea continuing throughout time until we meet the more recent second idea. The first idea is associated with 'had'. Example: By the time they left Toronto, they had visited the CN Tower three times.

In the question, Tarduno's group found the evidence AFTER the rocks were magnetized. I don't see how 'had' can be associated with the 2009 finding using Past Perfect structure.

To further strengthen this point, Past Perfect should only be used when the timeline of actions is unclear. We are told one action happened in 2009, the other 3.45 billion years ago. Past perfect is not needed.

bgpen, what is the source of this question? OG? Manhattan?

bpgen- what is the source of the question??

Thread starter , whats the source ?

Also the explanation for answer option A is flawed as other have suggested in previous posts .

Well, it's excerpted from well known Scientific American journals. do Google..

Guys..I could not understand why do you lock your eyes on only 'rocks were magnetized' words...

See my explanation again, specially see TWO events, don't be stereotype...think bit wider..

1. 'Group had found..' First one that started earlier...
2..Made'coinciding with the direct evidence for Earth's first life..'
This proof was established after Group had found rocks..

Hope this help. (not helps! ouchh!)

I found the article here: https://www.scientificamerican.com/artic ... o-start-up

bpgen, the excerpt you gave doesn't say anything about the group finding rocks. It just says they found evidence ABOUT some of the rocks. In the paragraph before your excerpt, it does say they found the rocks, BUT NOT IN THE EXCERPT YOUR QUESTION ASKS. Therefore, your explanation/answer is in fact flawed, and the answer E should be correct.

But that's not even important now. Let me get this straight: you just took an excerpt from an article and made your own question? You don't have an actual answer because it's not an actual question? Sorry, are you an employee of GMAC? Do you write GMAT questions?

You do realize the author could have MADE A MISTAKE in the article? The author isn't a creator of the GMAT exam, he isn't focusing on such specific grammar concepts as the GMAT will.. It's very possible that a small grammatical error slipped by, and we are therefore trying to answer a question that's been wrong the entire time.

Unreal. Thanks for wasting an hour of my time!

Cool down Man! Let me explain you the motivation behind such quiz!

Don't always hunt for 'REAL' question, "REAL' question. What do you mean by real question? Every time you see question, you might always think about 'Is it real question?' Your attitude is just PASS(score some number) in GMAT not just learning SC/grammar.. or participate any debate to put your thoughts or defend your thoughts! Don't follow such poor mentality. Grow up Man! Let us follow you as a Expert/leader..not that you keep hunting for GMAT/C real question/answer and walking far behind us ...

Do you agree? if not..then say so...

Let me know if you still have any concerns! btw, did you ever put thoughts about the explanation I gave!

I strongly disagree. This is a board for people studying to 'Beat the GMAT'. If every reader who thinks they're smarter than everyone else posted a question, this board would be useless. We would be left with hundreds of questions by people who think they know the answer, when in reality many would be wrong. If you want to have a discussion on Past Perfect, start a discussion; don't try to hide a lesson within a question you've disguised to look like a real GMAT question.

Yes, I did read your explanation, but to be honest your English doesn't make much sense. Not that your answer doesn't make sense; I literally cannot understand your English, sorry. I did try to the best of my ability, and my concerns follow:

1. 'Group had found..' First one that started earlier...
2..Made'coinciding with the direct evidence for Earth's first life..'
This proof was established after Group had found rocks.."

I understand point #1, but in point #2, what does 'made' even mean in that context? And continuing onwards in your explanation, you state "This proof was established after Group had found rocks.." No, the excerpt does not state that - no where does it say that Tarduno's group was the one who found the rocks. It says it in the article; NOT the question. That's my problem with your question.

I did however get a laugh out of you suggesting I am not participating in debate/defending my thoughts. Au contraire, mon frere. The reason you have so maturely told me to "Cool down Man!" is because I am, in fact, defending my thoughts

Appreciate your concerns, kidcorpo!!!
You are so nice hearted and most wonderfully..you grown up so fast...

And sorry if I wasted your valuable time.

Now two things:
1. You can just keep copying real GMAT question either to throw question to others or to clarify your doubts..Agreed, it is helpful as different person has different thoughts and you can get gist out of it. But somehow all know the answer....Why not try second option below to implement grammar/strategy rules what we learnt already into a practical question?

2. To get very NEW GMAT question, who will provide that? Why not to frame a NEW question and let's start a debate...Obviously correct answer come up but different person would have different thoughts.

Now coming to your concerns

everyone else posted a question, this board would be useless

I totally disagree...in fact BTG is encouraging all of us to post questions, as many as you want.. People are smart..They can find out where to look and what to ignore..If they do not find interest, they will not spend any time at all...believe me!

Anything you want to share?

Thanks!

You've misread my response. I think it's incredibly important for BTG members to post questions, provided they have a definite answer. Otherwise, we would have hundreds of incorrect questions with incorrect answers, similar to the question you've given.

I think your second option is a perfectly valid one, provided you give an early disclaimer stating that you have made up this question yourself... That your following question is not an actual GMAT question and therefore does not have a definite answer. Many here are studying on a time budget; wasting time arguing about an invented question is detrimental to many.

With that said, this is now becoming a bigger waste of time for both of us. I've made my point, you've made yours.

The OA to your posted question is, in fact, E - for the reasons myself and nearly everyone else have posted. Your confusing answer for A is not helping anyone.

Thanks for your effort. Good luck with your studies.

I'm sorry, but your grammar plainly SUCKS. You can't even construct half-decent sentences. I don't understand why you are making fake GMAT questions. Instead, you should be focusing on your fundamental ENGLISH.

You are stubborn and misleading. I hope you learn some grammar or else you'll epically fail the GMAT.

I will opt for E

Guys can u see the difference between following sentences

In 2009 Tarduno's group had found that some of the rocks were magnetized 3.45 billion years ago-roughly coinciding with the direct evidence for Earth's first life, at 3.5 billion years ago. Here the "Roughly...ago" modifies "had found"
and

Hence A can be the answer in first case. E is right had it been the second case

E

You are stubborn and misleading.

I am not convinced with your argument, bigmonkey31! The bottom line is that, we are really discussing/implementing grammar rules to improve our Verbal skills. But your attitude is different, who could bluntly say to other that 'your grammar plainly SUCKS' and proving himself the 'KING of Grammar'.. Did you even ask yourself what's the message are you sending to community/Forum?

It looks like you are a frustrated guy, not able to start a healthy debate and even more, you don't know how to behave in a public forum like this BTG.

I thought world might be free from IDIOTS!!! But after interacting with you, I found that it's wrong. You are truly an IDIOT and you need immediate kicks on your A**.

Excuse me if I'm too harsh.

Here everyone has viewpoint and they can put their viewpoint and more importantly they should not discourage others..instead everyone should encourage each other or advice/guide in a nice way..

Do you agree that...People like you really divert one's +ve energy into -ve one. You are worthless!!!


And appreciate max37274, for putting a nice thoughts..

I think your second option is a perfectly valid one, provided you give an early disclaimer stating that you have made up this question yourself..

And I totally agree with you, kidcorpo and appreciate your viewpoint. You could notice also, I already put subject line as "Sentence Correction-quiz-3". And as per your advice, yes we could put more disclaimer to make aware that question is not from any gmat question, constructed only for debate...

Hope this help.
