今天看到一道GWD里逻辑题，和本月洛基JJ很像~和大家分享下哈

17挖金子v1挖金子，之前用一个C开头的东西，可是用这个东西会污染环境。做study还有弥补这个污染会导致挖金子的人的cost上升。现在发现了一种O，这个O很厉害，可以把金子一点一点吃进去，然后再一次吐出来，成一个大金子（囧）。用这个O可以省钱。问evaluate。
选项有C造成污染的可能性有多大，C要花多少钱，O是不是和C一样可以release到surrounding里。这题真的不会，磨蹭了好久最后随便选了一个。 By Q50 V35 710 chenys1990

V2 也看到了那个挖金子的狗狗，没仔细看，不剩多少时间了，提炼出个大概，最后问的是evaluate能不能achieve那个目标，题目说的好像找了个新方法在挖的过程中减少环境的污染，挖金子的人就都纷纷用这个方法来捞钱。我选的是金子用这个方法会不会被挖出来吧，好像是这个意思，大家审慎着看，千万别误导大家啊。 by 梦想守护者

上述这个是这个月JJ的一道题
下面是今天在做GWD时发现的一道很类似的题目

Because mining and refining nickels is costly, researchers have developed an alternative method for extracting nickels using Streptanthus polygaloides, a plant that absorbs and stores nickel from the soil as it grows. The researchers incinerated a crop of Streptanthus they grow in nickel-rich soil. By chemically extracting nickel form the ash, they produced 100 pounds of nickel per acre of land at a total cost per pound slightly above that of current mining.

Which of the following, if true, most strongly supports the conclusion that the use of Streptanthus to extract nickel will be commercially adopted?

A.The season in which the researchers grew Streptanthus was an unusually favorable one, with the right amount of precipitation to maximize the growth rate of Streptanthus.

B.Because lowering the concentration of nickel in the soil can make land much better for agriculture in general, a plot in which Streptanthus has been grown and harvested can be sold for substantially more than it cost

C.More air pollution is generated for each pound of nickel produced by extracting it from Streptanthus than is generated using conventional mining and refining

D.The land on which the researchers planted Streptanthus was unusually free of the various weeds that can compete with Streptanthus for water, nutrients, and sunlight.

E.It is extremely rare for soil to contain higher concentrations of nickel than the concentrations present in the researchers’ experimental plot.

B是正确选项，做的时候我还选了D， 后来再看清题目发现题目问的是“commercially adopted” 那么明显B更好了

      这个题的题目和JJ很像，但选项貌似有些不同， 请G友们谨慎参考~~
