Hello,
adkikani. You touched on some interesting points. To be honest, I prefer to go through SC questions in a less strict grammatical sense, using the process of elimination all the while... in other words, in a typical, (perhaps) lazy native speaker manner. The following is what helped me answer the question correctly in 47 seconds. I share my thoughts here to echo some of your own and perhaps provide a few insights:
sacmanitin
The increased popularity and availability of televisions has led to the decline of regional dialects, language variations
which originate from diverse ethnic and cultural heritages and perpetuated by geographic isolation.
(A)
which originate from diverse ethnic and cultural heritages
and perpetuatedThe restrictive
which does not bother me so much that I would outright dismiss the answer, but the missing linking verb in
are at the end of the underlined portion is a deal-breaker. You cannot say
originate... and perpetuated without such an addition. The former is a verb, the latter a participle.
sacmanitin
(B) that originated from diverse ethnic and cultural heritages
and perpetuatedThis is the kind of answer that would be easy to pick in a hurry, but it does indeed suffer from the same problem as (A). Because of
by in the non-underlined portion, we need a linking verb to indicate that language variations did not in and of themselves perpetuate—it took unnamed
speakers of those dialects to perpetuate them. The correct version would read,
that originated from... and were perpetuated by... sacmanitin
(C)
originated from diverse ethnic and cultural heritages and perpetuated
Without
that,
originated here becomes a modifier, just like
perpetuated. Problem solved, right? Unfortunately, no. If
regional dialects are being defined as
language variations..., and the definition is to extend into the present (to indicate that regional dialects still exist), then
originating is necessary instead. The past participle makes it sound as though all the regional dialects have died out, but the sentence indicates a
decline only in such language use.
sacmanitin
(D)
originating from diverse ethnic and cultural heritages and
perpetuatedNow the meaning issues have been resolved, and we have two participles that fit the context of the sentence. Regional dialects
that are still spoken by some were perpetuated by geographic isolation, but now the TV is threatening the continued use of such dialects.
sacmanitin
(E) originating from diverse ethnic and cultural heritages and
perpetuating Perpetuating by does not make sense here. The languages in question are in decline, not perpetuating. The geographic isolation of the
past, pre-TV, helped these languages perpetuate.
I suspect a different Expert will provide a more grammatical analysis of your questions, but I am sticking to what is fun for me to explore, in hopes that in the process, I may have answered a few of your questions. This issue in real life does resonate with me. I would recommend the book
Vanishing Voices: The Extinction of the World's Languages if you want to read a fascinating but sad account of what humanity loses when these so-called
fringe languages die out.
I appreciate the mention. Good luck with your studies.
