OFFICIAL EXPLANATIONProject SC Butler: Sentence Correction (SC1)
THE PROMPTQuote:
According to new studies, the prospect of earth getting hit by a comet from the frigid outer reaches of the solar system is
so unlikely as it is alarming.• If we glance at options B through E, we should get a sense that the sentence is stating two things about the prospect of earth getting struck by a comet:
(1) that the prospect is unlikely, and
(2) that the prospect is alarming.
"Unlikely" and "alarming" are similar in degree.
• Diction and idiom
A few idioms are tested a fair bit, although most of the time an option with an idiom error will contain another kind of error.
Comparison idioms are relatively common.
→ To show similarity, equivalency, or equality, we As X As Y
→ AS is always paired with AS and never with THAN or THAT.
The correct idiom in this case is
. . . AS . . . AS . . .
→
Abhi is as tall as Knut. (same characteristic, equal intensity or degree [of talleness])
→
Adeline is as generous as Deborah is stingy. (opposite characteristics, equal intensity)
THE OPTIONSQuote:
A)
so unlikely
as it is alarming.
• not idiomatic
→ So X as Y is not idiomatic or sensible. It's not a thing. We need AS to be paired with AS.
So X as TO Y is a thing, but connotes something different from As X As Y. See Notes.
ELIMINATE A
Quote:
B)
so unlikely that it is alarming.• grammatical but nonsensical
→ So X That Y is an idiom, but it does not make sense in this context.
→ So X that Y distorts the meaning of the sentence by suggesting a causal relation between the two situations.
If the prospect of earth being struck by a comet are unlikely then the prospect should actually
not be alarming.
ELIMINATE B
Quote:
C) as unlikely as
alarming.
• bad comparison
→ this option seems to compare
a situation with the word
alarming.
If you are not sure, keep it and look for a better answer.
ELIMINATE C
Quote:
D) as unlikely as it is alarming.
• I do not see any errors
→ the AS ... AS pattern holds
→ the option is logical
KEEP
Quote:
E)
as unlikely
that it is alarming.
[/quote]
• nonsensical and not idiomatic
→ AS should be paired with AS, not THAT
→ the sentence does not mean anything. A native speaker truly cannot parse these two words placed in this way.
ELIMINATE E
The answer is D.NOTESIn this post, here I discuss SO THAT, SO AS TO, SO X THAT Y, and SO X AS TO Y.
