In A, twice as much as 1981 seems to compare a percentage to a year. Eliminate A.

In B, twice as many as 1981 seems to compare a percentage to a year. Eliminate B.

In D, it (singular) cannot be used to refer to 42% of graduate students (plural). Eliminate D.

In E, that of 1981's is an error of redundancy. The possessive construction 1981's is not necessary; that of 1981 would be sufficient all on its own. Eliminate E.

The correct answer is C.

Hi,

Can you please provide a bit more info on why D is incorrect? I am still a little confused ...

For example, here choice C is correct.
In the 1980's the rate of increase of the minority population of the United States was nearly twice as fast as the 1970's.
(A) twice as fast as
(B) twice as fast as it was in
(C) twice what it was in
(D) two times faster than that of
(E) two times greater than

Thanks!

In B, twice as many as 1981 seems to compare a percentage to a year. Eliminate B.

In D, a percentage cannot be double what it was. A percentage can be double ANOTHER percentage, but it cannot be double itself. Eliminate D.

In E, that of 1981's is an error of redundancy. The possessive construction 1981's is not necessary; that of 1981 would be sufficient all on its own. Eliminate E.

The correct answer is C.

The rate can be twice what it was. But 42% of graduate students cannot be double what THEY were because 42% of graduate students refers to the actual people. People cannot be double what they were. And the pronoun they -- we cannot use it to refer to 42% of graduate students -- would be inappropriate because we're not talking about the same students in the two years being compared.
