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/开垦 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.
Which of the following, if true, most helps to account for the drop in reclamation costs described?Q：开采费用下降原因

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. 无关
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.使用需求减少和开采花费变化无关
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.
因为贵的不搞了，所以便宜了，make sense 选C
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.无关
E.     As compared to twenty years ago, a greater percentage of the coal mined in Balzania today comes from surface mines.没提及花费

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
大花店10%收入来源于种子sales→种子最popular
A：可能种子单纯贵罢了，很少的量就能搞到10%sales，而popular应该是看quantity多少的

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
各分公司avg pay↓→员工可能会跳槽
A：avg工资可能是扣的executives级别的，随便扣点就可以拉下来了，可能这些员工本来工资也低于avg

1. 政府要求开垦新的矿要pay=>如今开垦的成本比之前少了一半
原因-- 开矿的人少了
C
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
P：某种子最popular
C：该种子占了最大花店营收的10%
削弱-- 只有一个花店受欢迎吗？其他地方的花店也卖的好吗？花店总共卖多少花呢？（总数未知）
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

评价工资降低--公司员工会在别的地方找工作
削弱-- 虽然工资降低，但是别的地方工资也差不多

1. P: 巴尔扎尼亚政府对煤矿收填坑费，且复垦技术没有提升C: 费用仅为法律生效前费用一半
解释： A 加上复垦费用巴尔扎尼亚煤矿运营成本也比其他国家的低  B 煤炭燃料使用下降  C山区不再开采，因为填坑费用高 D 露天煤矿成本加上填坑费用后成本也比地下煤矿的低 E 和二年前相比露天煤矿出煤量占比更大
2. P: 最大花店收入的10%都来自于一个种子
C: 好多gardener觉得那个种子最popular
削弱： 最大花店买的种子类型少于十/有其他收入大于10%
3. P: 一公司在各个区域的各分公司的总体平均工资降低了
C：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
削弱： 各地均降薪且降薪后水平低于该公司各分公司水平

2.        美国花店

问：削弱
花店卖的花小于10种（小于始终意味着，每种花收入都大于10%）

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
其他地方的工资下降幅度比这个公司还大

问题不大35
