107. American productivity is declining in relation to Europe’s; the energy expended per unit of production in the United States is as much as twice that expended in West Germany.
(A) as much as twice that expended in West Germany
(B) as much as twice that of West Germany’s expenditure
(C) up to two times of West Germany’s expenditure
(D) up to two times what West Germans expended
(E) up to double the West German expenditure
这道题没看明白，twice 不是只能修饰数量词吗，另外，twice可以在as much as 后面吗？
如果不考虑比较物对称，up to two times of 对不对？
