ReedArnoldMPREP - how would you pick (e) over (c) ?
too me (c) seems okay.
here is my analysis on (c)
people keep saying (c) has a comparison problem - i am not sure i see it
- i dont believe "
twice or double" are comparison markers to begin with
there is a clear antecedent for "those"
-- the antecedent of "
those" is 20 % of adults (20 % of adults is plural per my understanding)
-- analogy : 10 % of girls in class 1A
are taller than those in class 1b
people are saying (c) has a pronoun issue
- i dont see why
those is wrong ==
those has a modifier in front
- the modifier in front of
those is the "the 1977 survey reported"
- that way the
those is not a stand-alone pronoun (
those is attached to a modifer)
"those" is NOT the 20% of adults who used cocaine. The "Those" here is the people in 1977, the number of which is the 20% value is twice as large as (double and twice are quantifier-comparisons).
But if we're generous and say that "those" can refer to the adults in 1977 who used cocaine, there's a problem with meaning. Note that 'those' is not itself a quantity--it's a group of people (not the number of individuals *in* the group). I can't say "This group of people is two times that group of people." You might know what I mean by that, because you have context clues, but what I really mean is "The number of people in this group is two times the number of people in that group." So C is saying "20% of the americans in 1979...was two times the people in a 1977 survey."
A number (20% of americans) is not 'two times people.' It should be two times a NUMBER of people.
Thanks so much

You dont think if replace "those" with this antecedent - the sentence makes sense ?
"those" = 20 % of young adults.
Quote:
option C interpretation 1) 20 percent of young adults used cocaine in 1979, twice 20 percent of young adults the 1977 survey reported
I thought this was okay because we are comparing
(A) 20 % of young adults in 1979
vs
(B) 20 % of young adults in 1977
(A) = 2 x (B)
Mathematically, that would be saying 'the population of young adults doubled, (while the % has remained the same)' That's not what this sentence is saying. This sentence is saying "The number of young adults who have used cocaine has doubled."
But again, *"Those" is people not a number of people.* You cannot double "People."
Those cannot replace 'a percent of people' because a 'percent' is one single thing (namely, a value that represents a quantity, but *itself* is one thing).
"20% of all people claim to have served in the military, but those in that group who actually have are typically unwilling to boast about it."
'those' is 'the people in the 20% of all people who have served in the military.' Those stands for the PEOPLE.
"20% of eligible adults served in the military in 2000, a figure twice that of 1970."
'that' represents the '20% of eligible adults,' the NUMBER, not the people.
