The correct idiom is 'method for diagnosing'. Eliminate (D), (E). The subject 'coronary angiography' is interrupted by the phrase, 'a sophisticated...'. As soon as that parenthetical phrase ends we need a verb that goes together with the subject. Only 'involves' does this. Therefore (C).

Hope that helps!

@maybeam

regarding your question
when speaking in manners of procedures or a way to do something (using the word method), use "method for".
But when speaking in manners of using a certain method to find out or conclude something, use "method to".
Eg. Use the negating method to weaken the arguments conclusion.

Using the explanation above there is only one answer choice that stands out:
C) Coronary angiography, a sophisticated method for diagnosing coronary disease, involves the introduction of dye into the arteries of the heart and is now administered selectively, because it uses x-rays to observe cardiac function. Correct structure.

Anwser choice D might be confusing at first but the use of "that" incorrectly modifies disease.
Coronary angiography, a sophisticated method to diagnose coronary disease that involves the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses x-rays to observe cardiac function.

Hope this helps!

PS: i find it very helpful that you keep posting all this questions in forum, for discussion, etc. Kudos to you @maybeam!

Hi!

When you see lots of clauses and phrases, think modification.

The problem with D is the phrase "that involves the introduction of dye"; since that phrase immediately follows "coronary disease", that's what it modifies. However, that doesn't make any sense; we want that phrase to modify "coronary angiography".

In C, we have a comma after disease, turning that whole clause into a parenthetical comment that we can ignore when evaluating the sentence. So, C actually reads:

Quote:
Coronary angiography, blah blah blah, involves the introduction of dye...


which is exactly what we want.

I agree that its the angiography that involves the introduction of the dye and not the diesase.
But is the usage
Quote:
method for
a correct usage.

I was confused b/w the forms

method for and method to

and choosed method to as right, though it turned out to be wrong. Can somebody help me on this?

i have still confusion between A and C. i found A grammatically correct but it is wrong meaning wise as it says "disease involves introduction of dye ..". but in C, there is something wrong with "and is". can anyone please explain the difference between A and C.

although i selected A, now i realize that A is wrong meaning wise.

C is correct.
CA,..., involves...., and is administered...

Coronary angiography, a sophisticated method for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses x-rays to observe cardiac function.

Here the present participle "involving" modifies the immediately preceding noun disease. But disease doesn't involve the introduction of a dye into the arteries of the heart but rather the method involves that. Therefore A is wrong.

C correctly describes the method by saying two things using parallel predicates: invoves... and is administered...

Hope it helps

Coronary angiography, a sophisticated method for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses x-rays to observe cardiac function.

meaning : CA is a sophisticated method. CA involves bla bla.
CA is NOW administered selectively. Why administered selectively?? because CA uses X-rays to observe....
( Here the reason provided is only for "now administered selectively " and not why it involves dye ,,)


(C) for diagnosing coronary disease, involves the introduction of dye into the arteries of the heart and is now administered selectively, because it uses
- meaning : CA involves the intro of dye... and is now administered selectively. why?? (Here "because " is providing a reason for the entire clause " involves and administered) . I disagree with this answer choice.

We have to choose best answer which makes sense. . Here structurally provoding a reaon for "involves" is not right.

I disagree with the OA .
P.S. I agree that rest all are grammatically incorrect but even C is logically at fault.

[quote="SoniaSaini"]Coronary angiography, a sophisticated method for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses x-rays to observe cardiac function.


(A) for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses( involving is modifying disease,not correct)

(B) for diagnosing coronary disease involving the introduction of a dye into the arteries of heart, is now administered selectively, because of using(same as in A,no subject in clause)

(C) for diagnosing coronary disease, involves the introduction of dye into the arteries of the heart and is now administered selectively, because it uses(prepositional phrase correctly modifies C. Angiography,involves an action verb correctly describes the C.angiography)

(D) to diagnose coronary disease that involves the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses( that modifies disease illogically,it is not disease that involves rather it is CA)

(E) to diagnose coronary disease involving the introduction of a dye into the arteries of the heart, which is now administered selectively, uses(involving is incorrectly modifying disease,which is incorrectly modifying heart)

Would go with choice C

Thanks

Angiography, and not disease, involves "introduction of dye". Hence, for the correct meaning, "involves" must refer to "angiography".
Only C does that correctly.

Hi,

can anybody tell me why the "dye" in C is correct? should it not be "a dye"?

As far as I see, outside American English, I am not sure whether there is any difference between 'method for' and 'method to'. While 'method to', 'method of', 'method in' are described by many dictionaries, they have completely ignored 'method for'.
The Free dictionary even says that the phrase 'method for diagnosing' is not found in the Dictionary and Encyclopedia.

I would wait for someone to cite a dictionary link that describes the difference. Nevertheless, I still take Chris Lee's reasoning that method for diagnosing is the correct idiom as he ought to know better.

In addition, is it at least there in any of the idioms list flashed by the Gmat training companies?

Therefore, this question has to be decided on other merits than on idioms, I believe.

I have read in some books that "that " is not as strict as "which" and need not be close to the subject that it modifies. Option D structure is much better than option C, which uses an "and" in the sentence.
Please explain me why the answer "C" is preferred over "D"?

D and E can be eliminated right off since the correct idiom is ‘method for diagnosing’. Out of the remaining options, only C has the correct form of ‘involve’, so C is the correct answer.

I go with C, but I have a question . i.e the stmt like

Coronary angiography, a sophisticated method for diagnosing coronary disease, involves the introduction of dye into the arteries of the heart and is now administered selectively, because it uses x-rays to observe cardiac function.


Will "it" (underlined abv) refer to the preceeding noun, if any, like heart in this case ? Becoz i want to confirm my understanding that the modifiers seperated by commas do not modify the actual statement i.e Coronary angiography uses x-rays to observe cardiac function.

The basic tenet is that a pronoun should refer back to an eligible noun, whether is the near one or the farther one. Eligible means something that makes normal sense, not inappropriate meaning. The tenet also says that these pronouns normally fall back on the subject as the first choice but not necessarily. Supposing in this case, if the sentence happened to be, let us say, 'The doctor clarified that CA involves pumping a dye into the heart and therefore it is used selectively', then it cannot refer to the Doctor since we do not use 'it' for a Doctor.

Nor can we use it to refer to the disease or the heart, because neither a disease nor a heart can ever use x-rays. CA-only uses x-rays.

However, to your query about ' modifiers separated by commas' let me say that it should not confuse between a modifier and a pronoun. 'Because it uses x-rays to observe cardiac function' is a subordinate clause and not a modifier. The 'it' you have underlined is not a relative pronoun either such as 'comma+ which' or ' that', which have an obligation to refer to the nearest
Noun. That is the reason they are called relative pronouns.

You might also note that modifiers separated by comma +verb+ing (Ex: Tom always strived hard to some be admitted to the Wharton, dreaming about the mouth-watering placements he could get in the campus interviews.) modify the entire statement before which involves a doer and the doer's action.

You may perhaps like to clarify what you wish to convey by your idea that the modifiers separated by commas do not modify the actual statement.

Thanks.
