In 1980 the United States exported twice as much of its national output of goods as they had in 1970.
(A) twice as much of its national output of goods as they had
(B) double the amount of their national output of goods as they did
(C) twice as much of its national output of goods as it did
(D) double the amount of its national output of goods as it has
(E) twice as much of their national output of goods as they had
I see C is the correct answer. But i am puzzled by "of its national output of goods" contruction. why add an"of" before the its national output? AND 1.Whether I can restructure the sentence as following: In 1980 the United States exported twice of its national output as much as it did in 1970. 2. is "twice of" in original sentence similar with handreds of/thousands of ? 3. AND I THINK: In 1980 the United States exported twice its national output as much as it did in 1970(&equal to:In 1980 the United States exported twice as much its national output as it did in 1970 ). NO "OF" is 100% correct?
Thanks!
