Quote:
In his study on the failures of the American educational system, Professor Harris states that over two million high school seniors in this country are functionally illiterate, and
at least as much as four million others cannot read at an eighth-grade level.
Analysis:
1.
That must be followed by another SV pair.
Here,
that is followed by two independent clauses. ",and" brings parallelism in.
So, what follows "and" must be parallel in structure to the clause "over
two million high school seniors(Subject) in this country
are(verb) functionally illiterate"
2. "four million" is countable. So, use of as much as is wrong.
lets go through the answer choices.
A. at least
as much as four million others cannot
B. at least as many as four million
and more cannot- much is replaced with many, which is the correct usage. But another error is introduced, 'and more' does not make sense.
C. more than four million of other students are
unable to- unable and cannot have different meanings. Cannot shows someones capability whereas unable does not.
D.
there was at least four million other students
unable to - introduction of "there was" is just wrong and two ICs are not parallel anymore.
E.
more than four million others(subject) cannot
read(verb) - concise and correct
