Day 61
1.        政府挖煤
Twenty years ago, Balzania put in place regulations requiring operators of surface mines to pay for the reclamation of mined-out land. Since then, reclamation technology has not improved. Yet, the average reclamation cost for a surface coal mine being reclaimed today is only four dollars per ton of coal that the mine produced, less than half what it cost to reclaim surface mines in the years immediately after the regulations took effect.二十年前，B出台了规定要求煤老板开采描边的煤矿需要支付回收费用，然而那时候回收科技不太先进。然而平均回收费用在现在只要4美元每ton，比在当时规定当生效的时候的一半还少。
Which of the following, if true, most helps to account for the drop in reclamation costs described?

A.    Even after Balzania began requiring surface mine operators to pay reclamation costs, coal mines in Balzania continued to be less expensive to operate than coal mines in almost any other country.  即使在B要求支付回收费用后，开采煤矿依旧比其他国家便宜
B.    In the twenty years since the regulations took effect, the use of coal as a fuel has declined from the level it was at in the previous twenty years.
自从规定生效的二十年里，使用煤为燃料比之前二十年下降了
C.    Mine operators have generally ceased surface mining in the mountainous areas of Balzania because reclamation costs per ton of coal produced are particularly high for mines in such areas. 煤老板停止开采山地表面的煤矿因为回收费用在那个地区太高了
D.    Even after Balzania began requiring surface mine operators to pay reclamation costs, surface mines continued to produce coal at a lower total cost than underground mines. 即使在要求支付回收费用之后，开采表面煤矿依旧比地底煤矿更便宜
E.     As compared to twenty years ago, a greater percentage of the coal mined in Balzania today comes from surface mines. 跟二十年之前相比，更大比例的B煤矿来自于表面煤矿。我选E，表面煤矿比例更大了所以变便宜了

2.        美国花店
好多gardener都觉得一个什么种子是最popular的，因为一个最大的花店10%的收入都是靠卖那个种子赚的。
问：削弱
最热门不一定能赚最多钱，可能就是因为跟成本价差不多才热门的
有其他种子很稀有利润很高

3.        地方降薪
一公司在各个区域的各分公司的总体平均工资降低了，在某地区的该公司员工很可能会到别的地方找工作因为工资低于平均的工资。
问：削弱
总体平均工资降低了可能是有的地方上升了，有的地方下降，这个某地区不一定是下降的那个地区
