OFFICIAL EXPLANATIONProject SC Butler: Sentence Correction (SC2)
THE PROMPTQuote:
According to a recent study, adolescents require nine hours of sleep every night, more than other ages require.
• In this sentence, we can logically compare adolescents with
people of
other age groups.
→ That is, make sure that you are comparing apples to apples.
In the nonunderlined portion, we read about
adolescents [who] require nine hours of sleep.
Adolescents = both a group of people and a group of people of a certain age.
The object of comparison must also be a group of people in a different age group.
THE OPTIONSQuote:
A) more than other ages require
• comparison error
→ This sentence illogically compares
adolescents with other
age groups.
Adolescents are people, not age categories.
ELIMINATE A
Quote:
B) more than people of other ages require
• correct
• This sentence logically compares
adolescents with
people of other ages.
• The word
more refers to
sleep.
In fact,
sleep is implied, this way: " . . . more [sleep] than people of other ages require."
KEEP
Quote:
C) more than those of other ages do
• comparison error
→ The word
those refers back to
adolescents.
This sentence thus illogically compares adolescents with
adolescents of (those of) other ages. Huh?
ELIMINATE C
Quote:
D) more than the requirement of other ages
• comparison error
→ This sentence illogically compares
adolescents with
the requirement of other ages.
Even if we are very generous and allow
the requirement to mean "number of hours of sleep," we are still improperly comparing adolescents with requirements— with
needs. Adolescents are people, not needs.
ELIMINATE D
Quote:
E) more than other ages
• comparison error
→ This sentence illogically compares adolescents with other
ages.
Adolescents are people who fall in a certain age range, but they are not themselves
ages.ELIMINATE E
