OFFICIAL EXPLANATIONProject SC Butler: Sentence Correction (SC1)
THE PROMPTQuote:
A 2011 Cornell University study found that restaurant menus that render prices as numerals without the dollar sign, as in 6.75,
encourages customers to spend more than menus that either use the dollar sign, as in $6.75, or that write out everything in words, as in six dollars and seventy-five cents.
• Meaning and structure?
Meaning: A study found that restaurant menus in which prices are written a certain way encourage customers to spend more money than menus in which prices are written in two other ways.
Structure?
Subject: menus, plural
→ the
that clause that follows menus is an essential modifier of menus and has nothing to do with the verb that should match
menusAt times, a
that clause
does influence the verb, such as when we have
one of the Xs.
Sometimes that construction takes a singular verb. Sometimes that construction takes a plural verb.
If you would like to know how that construction works, read
my post, here.
→ Verb? Should be
encourage, plural.
• Parallelism
We are dealing with the correlative conjunction
Either X or Y.Let's call Either X or Y a "structure."
The idiomatic structure has boundaries, this way: || Either X or Y. ||
The idiomatic structure's beginning signal is the word
either.To maintain parallelism, the word
that (1) must be placed once outside that structure, this way:
THAT || either X or Y ||
or
(2) must be placed twice inside that structure, this way:
|| Either that X or that Y ||
If the word
that is placed once outside and once inside, or only once inside, we lose parallelism.
Wrong, once outside, once inside: THAT || either X or that Y ||
→ Native speakers, be careful with this one. You are likely to hear it as unproblematic.
Wrong, once inside: || either that X or Y ||
Wrong, once inside: || either X or that Y ||
• Comparison MORE
→ If you see a comparison with the word
more in it, start looking for a
than.
Unless the comparative object is absolutely clear without
than, in a comparison, the word
more must be paired with
than.
THE OPTIONSQuote:
A)
encourages customers to spend more than menus
that either use the dollar sign, as in $6.75,
or that write out
• subject/verb disagreement
→ The plural subject
menus should be paired with the plural verb
encourage, not with the singular
encourages.• parallelism error - Either X or Y
X = use the dollar sign
Y = write out everything in words
→ The word
that ruins parallelism because it comes once outside the construction ("that either use") and once inside the construction ("or that write out")
→ Essentially, the use of the word
that after the word
or breaks the parallelism.
The word
that is already placed once "outside" (before) the construction, Either X or Y.
If
that is outside a correlative construction, the word "that" distributes to each element, X, and Y.
Now, oddly enough, if the word
that is inside a correlative construction (most likely after
either and before the X element), the word
that does
not distribute to the Y element and parallelism is lost.
In correlative conjunctions and other word pairings, whatever comes after the parallelism marker (in this case, EITHER) and applies to the X element does not carry over to the Y element.
Look at the placement of the word
that. These two are not parallel:
that either use [
before "either"]
or that write out [
after "or"]
ELIMINATE A
Quote:
B) encourage customers to spend more than menus
that either use the dollar sign, as in $6.75,
or that write out• parallelism
→ we have exactly the same parallelism problem as that in option A.
The use of
that after the word
or breaks the parallel structure between
either . . . or.
The word that is impermissibly "once outside and once inside" the structure Either X or Y.
ELIMINATE B
Quote:
C) encourage customers to spend more
as compared with menus
using either the dollar sign, as in $6.75,
or writing out• in a comparison, the word
more must be paired with the word
than→ there is no such thing as
more as compared with (ouch)
• parallelism
You can check parallelism in few ways.
The X and Y elements are not parallel.
(1) Look at the words after each constituent.
Either is followed by
the dollar sign. ← ← NOUN
Or is followed by
writing out everything in words. ←← PARTICIPIAL PHRASE (verbING phrase)
A noun and a participle phrase are not similar parts of speech and hence not parallel.
(2) Look at the words before and after the constituents.
In this sentence, we have
using either and
or writing out.
Wrong. [Participle EITHER] is not parallel to [OR participle].
We should have
either using and
or writing out. In this corrected case, both
either and
or are followed by participle phrases.
•
using and
writing? Those things aren't verbs. They are adjectives that describe menus.
Present participles (verbING words) can be used as adjectives that modify nouns.
The words
using and
writing out come from "reduced" relative clauses.
This is a relative clause:
that either useThis is a reduced relative clause:
either usingIf you want to know more about reduced relative clauses with present participle phrases (verbINGs), look at the last example given in
this very good short article, here.
You can also search my posts, in which I discuss reduced relative clauses a fair bit.
ELIMINATE C
Quote:
D) encourage customers to spend more than menus that either use the dollar sign, as in $6.75, or write out
• I do not see any errors
→ menus encourage is the correct subject-verb pairing
→ more is correctly followed by than
→ the word
that lies correctly once
outside the construction Either X or Y.
Because the word
that is outside the construction,
that distributes to both the X and Y elements and keeps them parallel.
KEEP
Quote:
E)
encourages customers to spend
more as do menus that either use the dollar sign, as in $6.75, or write out
• subject/verb disagreement
→ same problem as that in option A
• in a comparison,
more requires
than→ in comparisons, do not pair
more with
as. Pair
more with
than.
We need
more than.
ELIMINATE E
The answer is D.COMMENTSColor me gratified.
The quality of these answers is outstanding.
I'd have to bump almost all of you.
Big hint: future aspirants,
read the thread.
That three to five minutes of your life will show you different ways of framing the issues that plague these sentences.
Very nicely done, everyone.
