-twice as much as 1981
-twice as many as 1981
-double the figure for 1981
-double what it was in 1981
-a number double that of 1981's
OA to follow. Please provide your reasons too.
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.
