The following question is from GMAT Prep.

Cajuns speak a dialect brought to southern Louisiana by the four thousand Acadians who migrated there in 1755; their language is basically seventeenth-century French to which has been added English, Spanish and Italian words.
(A) to which has been added English, Spanish and Italian words
(B) added to which is English, Spanish, and Italian words
(C) to which English, Spanish, and Italian words have been added
(D) with English, Spanish, and Italian words having been added to it
(E) and, in addition, English, Spanish, and Italian words are added

Though i prefer option C to option E but i am confused between C and E. Also i would like to know what are the shortcomings in option D.

What is the OA?
Is the OA is C.
Option D is wrong because the sentence after and is not an independent sentence and it is a sentence fragment.
Option D is wrong because it "having been" is a passive voice construction and also the verb tenses are not parallel.
Option A is wrong as there a subject verb disagreement.
Option B also has a subject verb disagreement.

I agree with @parthatayi. My pick is also C.

i sort of agree. parthatayi wrote "D" for the first example when s/he should have written "E". in addition, we can't get rid of D just because it's passive voice, and there is no verb tense problem with D. instead we get rid of D because "having" must be a modifier here but it is totally unclear what it means..

Dear instructors:
OE said:"with" in D does not concisely modify the noun 'French', I don't know what does this explanation mean? in my opinion, I think 'with' in D is not a wrong point? am I right?

Also , I am not very clear about part of Tim's explanation: 'having must be a modifier here but it is totally unclear what it means..' I think "having been done" is wrong here because this usage express a different meaning which is against the original meaning.
'having been added' means the action--'add'--continues to now, but actually, the 'add' action finished in the past, and no more 'add' action any more. am I right on this point?

please kindly clarify, thank you in advance.

Don't worry about any OG explanation that uses the word "concise" or any of its synonyms. This is NEVER a valid reason to eliminate a SC answer choice. Whenever you see the OG use faulty reasoning like this, you should instead try to find the REAL reason the answer choice is wrong.

With respect to the "having" issue, the fact that I can't pinpoint a valid use of "having" is not much different from you finding that it conveys an inappropriate meaning. The bottom line either way is that "having" doesn't do what it's supposed to and is therefore wrong.
