MentorTutoring AjiteshArunUnderstood, learned something new for me.
Thanks Andrew, good morning and good day!
so now that B is correct, this begs the question what is wrong with
C then?
The only difference is presence of "methods that were introduced in the 1880s" and this logically makes sense to me.
How do you think B and C differ?
You can go by the subtle difference in meaning and parallelism that
TommyWallach has pointed out above, in
this post, but to be honest, whenever I see extra words in one answer choice that do not appear in another, I ask myself,
Are these words necessary? Do they add anything in the way of clarity that the shorter version lacks? Compare the two sentence side by side:
vscid
B. Pests had destroyed grape, celery, chili pepper, sugar beet and walnut crops in the region, but in the 1880s, more effective pest-control methods saved the citrus industry.
C. Pests had destroyed grape, celery, chili pepper, sugar beet and walnut crops in the region, but more effective pest-control methods that were introduced in the 1880s saved the citrus industry.
Now ask yourself, does the clause with the extra information
that were introduced add clarity to the sentence? Not really. At the very least, we can interpret (B) as saying that these
more effective pest-control methods were not being used until the 1880s. In fact, I would be fine with cutting out the embedded clause altogether and focusing instead on the placement of the phrase
in the 1880s:
Version 2:
C. Pests had destroyed grape, celery, chili pepper, sugar beet and walnut crops in the region, but more effective pest-control methods
that were introduced in the 1880s saved the citrus industry.
If the expression of vital meaning is the same, then I would ditch the sentence with the superfluous words. (The placement of the time phrase makes more sense anyway at the head of the second independent clause.) You asked about my approach, and what I have outlined above is exactly what led me to choose (B) over (C).
I hope that helps you out. If not, you need only ask a follow-up question.
