73、Officials at the United States Mint believe that the Sacagawea dollar coin will be used more as a substitute for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than four quarters, which weigh 5.67 grams each.
　　(A) more as a substitute for four quarters rather than for the dollar bill because its weight, only 8.1 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 lighter than
　　(C) as a substitute for four quarters more than for the dollar bill because it weighs only 8.1 grams, far less than
　　(D) as a substitute for four quarters more than the dollar bill because its weight of only 8.1 grams is far lighter than it is for
　　(E) as a substitute more for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than it is for
　　原文意思：
　　官员说一种钱被用于代替 four quarters 而不是 dollar bill 因为这种钱重 8.1 grams，少于 four quarters
　　题目分析：
　　读完 A 之后，感觉逻辑不同，more 是“更”的意思，而“rather than”是而不是的意思，这两个词汇放在一起逻辑上行不通。
　　B than 后面用 the dollar 而 more 后面用as a substitute for 一个加了介词一个没有加，不太好。
　　C 前面用 as than 后面用 for the dollar，比较对应，留着。
　　D than 后面没有介词，和前面的 for four quarters 无法对应，干掉。
　　E 又是 more 和 rather than 对应，干掉，而且后面那个 it is for 也挺恶心（发起者没变，不要再加代词了）
