OFFICIAL EXPLANATIONProject SC Butler: Sentence Correction (SC1)
THE PROMPTQuote:
Once weaved exclusively in the region around the Isle of Man, the kamir fabric is now available in several countries across the world and comes in red, blue, or green color or sometimes in a combination of all three marking a sharp departure from the time when it was only available in one color: a deep crimson red.
THE OPTIONSQuote:
A) red, blue, or green color, or sometimes in a combination of all three , marking
• a comma must precede
marking so that
marking can apply to the whole sentence
→ present participles (verbINGs) that are
not preceded by a comma modify the immediately preceding word or noun phrase, not the previous clause.
→ as option A stands,
marking modifies only
three or
combination of all three.
The phrase
marking a sharp departure, though, should be referring to the fact that the fabric is now more widely available and made in more than one color.
ELIMINATE A (or, if you don't feel comfortable, hold and look for a better option)
Quote:
B) red, blue, or green color, or sometimes in a combination of all three that mark
• The antecedent for the relative pronoun
that is unclear.
→ if the antecedent is
combination, the verb
mark should be
marks, because
combination is singular
ELIMINATE B
Quote:
C) red, blue, or green color, or sometimes in a combination of all three, and it marks
• The antecedent for the pronoun
it is unclear
HOLD tentatively, but look for a better answer. (I do not eliminate on the basis of pronoun ambiguity on the first pass.
Quote:
D) red, blue, or green color, or sometimes in a combination of all three, marking
• I do not see any errors
→ In this option, the phrase
sometimes in a combination of all three is non-essential and correctly flanked by two commas.
Marking correctly modifies the entire previous clause.
• The use of
or before
green suggests that the list of colors needs to end here.
• The phrase
sometimes in a combination of all three then can be best placed as a non-essential phrase that is enclosed by two commas.
KEEP
Quote:
E) red, blue, or green color, [or] sometimes in a combination of all three, which marks
• A connecting word such as
or should be placed before
sometimes in a combination of all three.The omission makes the result hard to understand and creates an illogical sentence.
• The antecedent for
which is unclear
ELIMINATE E
The best answer is D.→ Option D is better than option A because the usage of "marking" in D makes it clear that "marking" modifies the whole sentence rather than just "combination."
→ Option D is better than option C because D contains zero pronoun ambiguity.
Eliminate A and C if you have not done so already.
COMMENTSprivate07 , welcome to SC Butler.
As always, to aspirants who might want to post but need a little nudge: all aspirants have a standing invitation to post.
The options in this question feel a bit "slippery"—I'm happy to see that people are up for the challenge.
These answers range from good to excellent.
Kudos to all.
