还有一道逻辑：说是一个国家一开始用metal制造硬币 然后制造的面值比实际面值还要高，于是就打算换成用plastic制造，这样能大概只需要百分之多少的花费，反正意思就是能减少成本，结果有一个人称为A吧反对 说用plastic制造会容易被仿造
问题就比较奇怪了 如何来反对A增强国家这个制造币的方法的可行性
答案我就记这几个 A 一个是犯罪分子如果用plastic制造币花的时间比国家制造多了一倍
B few if any用metal造假币
C 什么什么 国家其实可以用一种便宜的金属造币能节省更多的成本貌似只需要60%的成本（这个数额比上面那个数额低）
D忘记了
E貌似也是一个五官选选
那么问题来了。。。考试的时候我觉得一个都不对 尴尬
请问是否是这道题：
Mayor: Migrating shorebirds stop at our beach just to feed on horseshoe-crab eggs, a phenomenon that attracts tourists. To bring more tourists, the town plans to undertake a beach reclamation project to double the area available to crabs for nesting.
Birdwatcher: Without a high density of crabs on a beach, migrating shorebirds will go hungry because shorebirds only eat eggs that a crab happens to uncover when it is digging its own nest.
Which of the following, if true, would provide the mayor with the strongest counter to the birdwatcher's objection?
A. Every year a certain percentage of crabs are caught by fishermen as bait for eel traps.
B. Horseshoe crabs are so prolific that given favorable circumstances their numbers increase rapidly.
C. On average, tourists who come to the town in order to watch birds spend more money there than tourists who come for other purposes.
D. The additional land made available by the reclamation project will give migrating shorebirds more space.
E. Some of the migrating shorebirds make only one stop during their migration from South America to Canada.
