106. (30167-!-item-!-188;#058&004112)

grams, is far less than

(B) more as a substitute for four quarters than the dollar bill because it weighs only 8.1 grams, far

(D) as a substitute for four quarters more than the dollar bill because its weight of only 8.1 grams is

(E) as a substitute more for four quarters rather than for the dollar bill because its weight, only 8.1

正确答案是C

谢谢大家的帮忙
