OA C

Hello,

The OA is C, but can someone please answer my questions.

Thanks,

Vineet

I've only recently begun studying for the GMAT, but I feel like throwing in my 2 cents about why I feel Choice 'D' is incorrect.

If we opt for Choice 'D', it yields:

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 with English, Spanish, and Italian words having been added to it.

At the very least, I believe a comma is necessary between the words "French" and "with". Otherwise, it looks like Cajun is basically seventeenth-century French with English, with the Spanish and Italian words being added.

Also, I think "having been added", the past participle form of the verb, is incorrect. Even though Cajun is partially defined by the French language of the past, the Cajun language itself is being considered in the present day (i.e. Cajuns speak (not "spoke")). Therefore, I think "have been added" is necessary, since it's the simple present perfect tense.

Maybe I'm way off with my reasoning, or maybe I'm in the "neighborhood". Anyway, that's how I see it.
